Latest / How Canadian Markets Work / Reading a Data Release Explained: Why Does Good News Crash the Market? | Canadian Investing
Transcript
- 0:00I want you to just take a slow, deep breath for
- 0:03a moment. Yeah, just let your shoulders drop.
- 0:06Exactly. We are going to step away from the noise
- 0:10today. Away from the flashing red and green numbers
- 0:13on the screens. Away from all the frantic shouting
- 0:16of those financial news anchors. Right. Instead,
- 0:20we're going to look at a really baffling paradox.
- 0:22Yeah. And I want you to imagine this. A highly
- 0:25anticipated jobs report is about to be released.
- 0:28The tension in the financial world is just, well,
- 0:30it's palpable at that moment. It really is. And
- 0:33then the numbers finally drop. Yeah. And they
- 0:36are fantastic. I mean, far, far better than anyone
- 0:38expected. So it looks like an absolute economic
- 0:41triumph for everyday people. Yeah. But the very
- 0:43moment that news drops, financial markets take
- 0:46a violent nosedive, the screen turns into just
- 0:49a sea of panic selling. It's wild to watch. It
- 0:51is. Why on earth would undeniably great news
- 0:54cause a massive market sell -off? It feels completely
- 0:56counterintuitive, right? It goes against literally
- 0:59every instinct we have about how good news should
- 1:01be received. Right. We expect applause for a
- 1:04strong economy. Exactly. And instead, the market
- 1:07treats prosperity as a threat. Welcome to our
- 1:10deep dive. Today we are taking a serene, unhurried
- 1:14walk through a fascinating stack of notes on
- 1:16how financial markets actually function. It's
- 1:19going to be a nice, quiet journey. Very quiet.
- 1:22Specifically, our mission is to look at how to
- 1:25read an economic data release. Our goal is to
- 1:28give you a shortcut to being genuinely well -informed.
- 1:31We want to teach you how to read economic data
- 1:34just like a professional. Yeah. So you never
- 1:36again find yourself misled by those sensational,
- 1:40breathless headlines. Because we really need
- 1:42to set the stage here, you know, by understanding
- 1:44a fundamental truth about the world of finance.
- 1:46And what's that? A number is never just a number.
- 1:49It's a story. And like any good story, it's wrapped
- 1:53in complex layers. Oh, definitely. Layers of
- 1:55expectations, quiet revisions and hidden compositions
- 1:58just waiting beneath the surface. Right. If you
- 2:01only read the headline, you are only reading
- 2:03the cover of the book. Okay, let's unpack this.
- 2:06Because to understand why markets can suddenly
- 2:09plummet on seemingly fantastic news, we first
- 2:12have to understand where the market actually
- 2:14lives. And it doesn't live in the present. it
- 2:18lives entirely in the future. That is so true.
- 2:20The future focus of the market changes the very
- 2:23definition of what constitutes news. Right, because
- 2:26before any significant economic data is released,
- 2:29whether that's inflation, employment, or GDP
- 2:32economists publish their forecasts. Yeah, a large
- 2:35group of them. And these individual forecasts
- 2:38are gathered together and aggregated into what
- 2:40we call a consensus expectation. The consensus
- 2:43expectation. Exactly. This consensus is what
- 2:46the collective of market believes is most likely
- 2:48to happen. And the market trades on that consensus
- 2:51well in advance. So let's say inflation is expected
- 2:54to come in at 3%. OK. And then the official release
- 2:57says it is exactly 3%. The market shouldn't move
- 3:00at all. Not a single inch. That information was
- 3:03already priced into every stock and bond. What's
- 3:06fascinating here is that in the financial markets,
- 3:08movement only comes from surprise. Surprise.
- 3:11Yeah. The expected outcome has already been bought
- 3:14and sold millions of times over before the data
- 3:17is ever published. The market was waiting to
- 3:19find out if its collective assumption was wrong,
- 3:21not if it was right. I love that. Think of it
- 3:25like watching a movie where someone has already
- 3:27told you all the spoilers. Oh, that's a great
- 3:29analogy. Right. You are sitting in the theater,
- 3:32eating your popcorn. If the movie ends exactly
- 3:35how the spoiler predicted, You don't gasp. No,
- 3:38you don't jump out of your seat. You just nod.
- 3:40Exactly. You only react if there's a sudden surprise
- 3:44twist that wasn't in the spoiler. Therefore,
- 3:47correctly predicting an economic number doesn't
- 3:49actually make you money. No, you have to correctly
- 3:51predict how the number will differ from what
- 3:54everyone else already assumes. Which is incredibly
- 3:56hard to do. It really is. And this helps explain
- 3:59why the common logic of the economy is doing
- 4:02well so stock should rise completely fails in
- 4:05practice. Right. Because if everyone already
- 4:07knows the economy is doing well, that optimism
- 4:10is already baked into the price of the stocks.
- 4:12You are paying a premium for yesterday's revelation.
- 4:14Which brings us back to our opening paradox.
- 4:17The good news is bad news trap. The classic trap.
- 4:21Yeah. How can a surprisingly strong jobs report
- 4:24a real twist in the movie caused the market to
- 4:28sell off? It comes down to the ripple effects.
- 4:31specifically regarding interest rates. The market
- 4:34isn't reacting to the jobs themselves. It's reacting
- 4:36to how the central bank will interpret those
- 4:39jobs. A surprisingly strong economic data release
- 4:43might signal to the central bank that the economy
- 4:45is running too hot. Right. And to prevent inflation
- 4:48from taking root, they might decide to hold interest
- 4:51rates higher for a longer period to cool things
- 4:53down. Exactly. I want to pause here. Because
- 4:56this is where the financial jargon usually gets
- 4:58incredibly dense. We often hear phrases like,
- 5:01uh, discounting future cash flows. Oh, yeah,
- 5:04that one always scares people off. It really
- 5:05does. Yeah. But let's look at it conceptually.
- 5:08Think of a stock as a promise of future payouts.
- 5:10Okay. If interest rates are high, you can get
- 5:13a great, perfectly safe return just by leaving
- 5:16your money in a bank or buying a government bond.
- 5:18Right, with basically zero risk. Exactly. So
- 5:21for a risky stock to be worth your money today,
- 5:25its price has to drop to make the potential reward
- 5:27attractive enough. High interest rates act like
- 5:30gravity on stock prices. Good news for the real
- 5:35economy like more jobs. higher wages triggers
- 5:38a fear of that gravity. That is the perfect way
- 5:41to visualize it. The gravity analogy works so
- 5:44well, the market is playing a game of anticipation.
- 5:47Right. It sees the good news, anticipates the
- 5:50central bank's heavy gravitational pull on rates,
- 5:53and sells the stock before that gravity can drag
- 5:56the price down. It's all about beating the gravity.
- 5:58So if the market is purely reacting to how a
- 6:01surprise compares to that spoiler, What happens
- 6:04when we discover that the spoiler they reacted
- 6:06to was completely wrong to begin with? Oh, well,
- 6:08that introduces us to the concept of phantom
- 6:11data. Phantom data? That sounds ominous. It kind
- 6:14of is. Most economic data you read in the headline
- 6:16is just an initial estimate. It's a rough first
- 6:18draft. Right. It's compiled very quickly based
- 6:20on incomplete survey responses and early data.
- 6:23So it's not absolute truth. It's just the best
- 6:26guess they have on that particular morning. Exactly.
- 6:29And as more complete information trickles in
- 6:31over the following weeks and months, the statistical
- 6:33agencies update their numbers. The revisions.
- 6:36The revisions. And they can be substantial. A
- 6:39month that is loudly and joyfully reported in
- 6:42the headlines as remarkably strong can be quietly
- 6:44revised to remarkably weak months later. When
- 6:48absolutely nobody is paying attention anymore.
- 6:50Precisely. The cameras are gone. Aye. Struggle
- 6:53to understand how a multi -trillion dollar market
- 6:55allows itself to be fooled like this I mean if
- 6:58these statistical agencies are constantly revising
- 7:01their numbers weeks later Why do Wall Street
- 7:04professionals still trade so violently on the
- 7:06first inaccurate draft? It's a great question.
- 7:09Shouldn't they know better than to bet billions
- 7:11on a rough draft? Oh, they absolutely know better.
- 7:13But they are bound by institutional mandates,
- 7:16algorithmic triggers, and just the sheer momentum
- 7:18of the herd. The herd mentality. Yeah. If an
- 7:21institutional manager knows the initial data
- 7:23is flawed and also knows that thousands of trading
- 7:26algorithms are about to buy based on that flawed
- 7:28data, they have to buy too just to ride the wave.
- 7:31Wow. So they are forced to trade the phantom
- 7:34data, because the illusion itself creates real
- 7:37market movement. Exactly. And here is the truly
- 7:40fascinating part for you, the individual reader.
- 7:44The revision to the old data is usually buried
- 7:46deep down in paragraph 6 of a news article. Right,
- 7:49while the flashy but highly inaccurate initial
- 7:52estimate for the new month gets all the bold
- 7:55font at the top of the page. You've got it. Wait,
- 7:58so to read the news correctly, you actually have
- 8:01to read it backward. You have to look at the
- 8:02quiet revision to last month before you even
- 8:05allow yourself to look at the headline for this
- 8:07month. Experienced professional readers operate
- 8:10exactly that way. Seriously. Seriously. The correction
- 8:13gets a fraction of the attention from the public,
- 8:16but it is often the most vital piece of the puzzle.
- 8:18Because it sets the actual baseline? Right. If
- 8:21you don't know where the baseline just moved
- 8:23to, the new number is completely devoid of context.
- 8:26OK, so once you accept that the baseline is constantly
- 8:28shifting and you finally allow yourself to look
- 8:30at the current number, our notes tell us you
- 8:33still cannot trust it. You really can't? Because
- 8:35the headline is an aggregate. It is a giant bucket
- 8:39holding a lot of different things, and aggregates
- 8:41hide all the interesting parts. This is the illusion
- 8:44of composition. The headline number is just the
- 8:47net sum of many moving parts, and those moving
- 8:50parts are frequently traveling in completely
- 8:53opposite directions. They can mask severe weaknesses
- 8:56with superficial strengths. Okay, let's slowly
- 8:58walk through a highly specific fictional scenario
- 9:02to really paint a picture of this. Imagine another
- 9:05jobs report. The consensus expectation, our spoiler,
- 9:09is that 15 ,000 jobs will be added. OK, 15 ,000.
- 9:12But the actual release comes out and says 40
- 9:15,000 jobs were added. A massive beat. Wow. Yeah,
- 9:19the headline writes itself, economy smashes expectations
- 9:21by 25 ,000 jobs. Exactly. It sounds like a massive
- 9:24victory on the surface. But let's look closer.
- 9:26Let's really look at it. We take a slow breath
- 9:28and read the composition of that number. We look
- 9:30inside the bucket. Right. And what do we see?
- 9:33Well, it turns out full -time employment actually
- 9:35fell by 10 ,000 jobs, but part -time employment
- 9:37rose by 50 ,000 jobs. Oh, so the net is a positive
- 9:4240 ,000, but the quality of the employment is
- 9:45visibly deteriorating. Yes. Reminds me of a company
- 9:48boasting that they made a million dollars in
- 9:51a single day. On the surface, it sounds like
- 9:53incredible business growth. It does. But if you
- 9:56look at the composition and realize they made
- 9:58that million dollars by selling their only factory
- 10:00to pay the rent, it's not actually growth at
- 10:03all. That's a perfect comparison. That's what
- 10:05happens when full -time stable jobs are quietly
- 10:08replaced by part -time precarious ones. The aggregate
- 10:11number goes up, but the foundation is cracking.
- 10:14And we also have to read backward. as we discussed.
- 10:17We look at last month's figure in this fictional
- 10:20release. Let's say originally it was reported
- 10:23as a solid positive 20 ,000 jobs, but buried
- 10:26in the notes it has just been revised down to
- 10:28a loss of 5 ,000 jobs. That is a 25 ,000 job
- 10:32downward swing to the past, which means the 25
- 10:35,000 job downward revision almost entirely cancels
- 10:38out the 25 ,000 job beat. of the current month.
- 10:41Exactly. The baseline sank right out from under
- 10:43us while we were busy celebrating the headline.
- 10:46Unbelievable. Now let's look at another detail
- 10:48in this release. The headline proudly states
- 10:51that the unemployment rate fell. That sounds
- 10:53fantastic. But we look at the composition again.
- 10:57Let's take a moment to understand the math behind
- 10:59the unemployment rate. It's important math to
- 11:02know. It isn't just the number of jobless people
- 11:04divided by the total population, is it? No. It
- 11:06only counts people who are actively looking for
- 11:08work. Right. So if a million people get so discouraged
- 11:11by a bad economy that they simply give up and
- 11:14stop looking for a job, they are erased from
- 11:17the equation entirely. They just vanish from
- 11:19the math. The math formula shrinks. The unemployment
- 11:22rate drops, even though not a single person actually
- 11:25got hired. In our fictional scenario, the rate
- 11:28fell only because the participation rate fell.
- 11:31It is a mechanical mathematical improvement masking
- 11:33a deep human discouragement. It's quite sad when
- 11:36you think about it that way. It is. And finally,
- 11:39if we look at the last detail in this release,
- 11:42we see that wage growth came in below expectations.
- 11:45Meaning people are taking home less extra pay
- 11:48than anticipated. Exactly. Their purchasing power
- 11:51is shrinking. So what does this all mean? Well,
- 11:54the headline boldly screamed an economic boom.
- 11:58But the composition, the quiet details underneath,
- 12:01reveals a weakening labor market. Yeah. Full
- 12:04-time jobs are bleeding away. The past was much
- 12:07worse than we thought. People are giving up the
- 12:09search for work entirely, and wages are softening.
- 12:12The aggregate lied, but the composition told
- 12:14the truth. And every single one of those details
- 12:17was in the exact same release. freely available
- 12:20to the public at the exact same moment This completely
- 12:23explains the wild chaotic nature of the market
- 12:26in the immediate aftermath of a data release
- 12:28The first few minutes are fiercely noisy Algorithmic
- 12:32trading bots might cause the market to plummet
- 12:34on the strong headline, assuming interest rates
- 12:36will rise. And then the market might completely
- 12:39reverse direction 10 or 15 minutes later as the
- 12:42human professionals actually sit down, read the
- 12:45composition, realize the economy is actually
- 12:47softening, and change their view on what the
- 12:50central bank will actually do. It's a roller
- 12:52coaster. Reacting immediately is clearly a terrible
- 12:56idea for anyone but a highly specialized high
- 12:58-frequency trader. Completely terrible. So now
- 13:02that we know the treacherous traps of expectations,
- 13:05the ghosts of revisions, and the illusions of
- 13:08aggregates. How do we practically apply this
- 13:10to our lives? Yeah. How do you, the listener,
- 13:13use this without feeling entirely overwhelmed
- 13:16by the sheer volume of data? Because it is overwhelming.
- 13:19It is. But we can outline a very practical, very
- 13:22deliberate defense plan. It consists of four
- 13:25steps, and it takes roughly three minutes per
- 13:28data release. Only three minutes. Just three.
- 13:30You don't need a degree in economics to do this.
- 13:32you just need patience. Okay, I love that. Step
- 13:35one, find the consensus expectation before you
- 13:38read the number. Right, because if you don't
- 13:40know what the spoiler was, you have no way of
- 13:42knowing if the movie actually had a twist. Exactly.
- 13:44You have to know what the collective market expected
- 13:47to understand if the news is truly news. Step
- 13:50two, read the revision to the prior period first.
- 13:53The backwards reading. Yes. Before you look at
- 13:55the shiny new number, look at how history was
- 13:58just rewritten in the footnotes. Understand where
- 14:01your baseline currently sits so you aren't comparing
- 14:04today's reality to a yesterday that never existed.
- 14:07That is so crucial. Step three, read the composition.
- 14:11Don't stop at the aggregate bucket. Look inside
- 14:13the bucket. Yeah. Is the job growth full -time
- 14:17or part -time? Or, you know, if we were looking
- 14:19at inflation, is it core inflation, which tracks
- 14:23the underlying persistent trend of prices? Or
- 14:26is it just a volatile headline number driven
- 14:28entirely by a temporary spike in gasoline prices
- 14:31that will reverse next week? Beautifully put.
- 14:34And step four, go directly to the raw source.
- 14:37Skip the news articles. Yes. If you are in Canada,
- 14:40go to Statistics Canada's website. If you are
- 14:42in the United States, go to the Bureau of Labor
- 14:44Statistics, read the actual release. Because
- 14:46the summary you read on a financial news site
- 14:48or a blog was likely written in 20 minutes by
- 14:50a rushed journalist. A journalist who was under
- 14:52immense pressure to file a story the very second
- 14:55the data dropped. Right. The original source
- 14:58is free. It is calm and it contains all the necessary
- 15:01nuance without the panic. Taking those three
- 15:04minutes changes you from a reactive consumer
- 15:07of news into an informed reader of data. It really
- 15:10does. But even with this defense plan, our notes
- 15:14highlight four major complications, four subtle
- 15:17traps hidden in the data itself that we need
- 15:20to gently untangle. These are the statistical
- 15:22quirks that can distort reality even when you're
- 15:25reading carefully. So what's the first trap?
- 15:28The first trap is seasonal adjustment. Oh, right.
- 15:31Because raw economic data is enormously seasonal.
- 15:34For example, retail hiring naturally spikes every
- 15:37December for the holidays. Right. Everyone needs
- 15:39extra help for the shopping season. Exactly.
- 15:42If statisticians didn't adjust for that, every
- 15:44December would look like an unprecedented economic
- 15:47boom. And every January when those temporary
- 15:49workers are let go would look like a severe depression.
- 15:52So statisticians use mathematical models to smooth
- 15:55this out, allowing us to see the true underlying
- 15:58trend beneath the seasonal noise. They do. The
- 16:01trap, however, is that these adjustments are
- 16:03merely historical models. They rely on the assumption
- 16:06that human behavior repeats itself reliably.
- 16:09Which it usually does until it doesn't. Precisely.
- 16:12When human behavioral patterns dramatically shift,
- 16:15like they did globally in the year 2020 during
- 16:17the pandemic, those historical models can violently
- 16:21distort reality. Because they're trying to smooth
- 16:23out seasonal patterns that simply no longer exist
- 16:25in the modern world. Exactly. Wow. OK, trap number
- 16:28two is single month noise, something we touched
- 16:31on earlier regarding the phantom data. A lot
- 16:34of this data comes from surveys. And surveys
- 16:36have inherent sampling errors. I mean, you are
- 16:39trying to measure the employment status of over
- 16:42150 million people by calling a few thousand
- 16:45households. It's an incredibly difficult task.
- 16:48And a single month release might show a massive
- 16:50unexpected jump or drop, but it might just be
- 16:53statistical noise. Just a quirk of who happened
- 16:56to answer the phone that week. Exactly. This
- 16:58is why looking at three month or six month rolling
- 17:00averages is vastly more informative than obsessing
- 17:03over a single month's fluctuation. The long term
- 17:06trend reveals the truth. The single data point
- 17:09is often a statistical liar. Very well said.
- 17:13OK. Trap number three is something called base
- 17:16effects. Yes, base effects. This one is incredibly
- 17:20important when we talk about inflation. Most
- 17:22gated is reported as year over year. We compare
- 17:25the price of a basket of goods today to the price
- 17:28of that exact same basket exactly 12 months ago.
- 17:32That rolling 12 month window is usually a very
- 17:35reliable way to measure price pressures. But
- 17:38it becomes deceptive if something highly unusual
- 17:40happened exactly one year ago. Let's walk through
- 17:42the math of a base effect to make it concrete.
- 17:45OK, let's do it. Imagine a geopolitical shock
- 17:47causes oil prices to spike to an unprecedented
- 17:50$150 a barrel last March. Right. And because
- 17:54oil is in everything, inflation for that month
- 17:56looks absolutely massive. Exactly. But let's
- 17:59say by this March, oil has settled back down
- 18:01to normal $80 a barrel. When the year over year
- 18:04inflation number is calculated today, it compares
- 18:06today's normal prices to last year's extreme
- 18:09spike. Oh, I see. The math will show a massive
- 18:12plunge in inflation. Yes. A politician might
- 18:16point to that plunge and declare that the cost
- 18:18of living crisis is solved. But the reality is,
- 18:20prices today didn't suddenly become cheap. No.
- 18:23The bizarre anomaly from 12 months ago simply
- 18:26fell out of the back of the rolling window. Wow.
- 18:28So the strange number you're seeing today...
- 18:30is actually being caused by the ghost of the
- 18:33past, not by anything structural happening in
- 18:36the economy right now. Exactly. It's a mathematical
- 18:38illusion. Here's where it gets really interesting.
- 18:41The final trap is a linguistic trap, as much
- 18:44as a mathematical one. It is the trick of changes
- 18:48in rates of change. This is a remarkably subtle
- 18:51manipulation. But it is incredibly powerful because
- 18:54it preys on our desire for good news. I think
- 18:57we all just want to hear that things are getting
- 18:59better. We do. Imagine a situation that is actively
- 19:01getting worse. Let's say a government deficit
- 19:05is growing larger every single year. The hole
- 19:07is getting deeper and the debt is piling up.
- 19:09Okay. But this year, the deficit grew by a slightly
- 19:13smaller amount than it grew last year. It is
- 19:16still growing. You are still digging the hole
- 19:18deeper. But a skilled communicator will deliberately
- 19:22weaponize the phrasing and announce the deficit
- 19:26grew more slowly. It's so sneaky. They take a
- 19:30negative reality, the fact that the hole is getting
- 19:32deeper, and frame the second derivative, the
- 19:35rate of change, to make a worsening situation
- 19:38sound like an absolute improvement. It exploits
- 19:41the cognitive load of the listener. It really
- 19:43does. Processing a slowing rate of deterioration
- 19:46requires a lot more mental effort than simply
- 19:49hearing the word slowing and assuming it means
- 19:51improving. It sounds like a victory when in reality
- 19:54it is just a slightly less aggressive defeat.
- 19:57It is a brilliant, entirely factual, and totally
- 19:59misleading way to communicate. Politicians, pundits,
- 20:02and corporate executives on every side of every
- 20:05argument use that exact trick. deliberately because
- 20:08they rely on the fact that most people do not
- 20:10take those three minutes to read the composition
- 20:12and understand the math exactly they rely on
- 20:15the emotional impact of the aggregate headline
- 20:17which brings us to the end of our quiet walk
- 20:19through the data it's been quite a journey let's
- 20:21slowly gather up the core message here economic
- 20:25data is not an absolute unvarnished truth handed
- 20:28down from on high no it is a rough messy first
- 20:32draft of history constantly subject to revision
- 20:34and reinterpretation The headline you see flashing
- 20:37across the screen in bright red or green is almost
- 20:41without fail the least informative part of the
- 20:44entire release. True. Actionable insight only
- 20:46comes from understanding the expectations that
- 20:48were already priced into the market. And acknowledging
- 20:50the quiet revisions to the past. Yes. And bravely
- 20:53looking inside the bucket to read the composition
- 20:55of the numbers. It requires a little bit of time
- 20:58and a little bit of stillness. Just three minutes.
- 21:00And if we connect this to the bigger picture.
- 21:02It leads to a rather profound thought to leave
- 21:05you with today. We live in a modern financial
- 21:08world dominated by algorithmic trading bots.
- 21:11These are vast server farms programmed to scan
- 21:14economic data releases and execute massive multi
- 21:18-million dollar trades based on aggregate headlines
- 21:20in mere microseconds. They're infinitely faster
- 21:23than we could ever hope to be. If you try to
- 21:26compete on speed, you will lose every single
- 21:28time. But perhaps the human inability to react
- 21:31that fast is actually a superpower. I love that
- 21:33idea. If the algorithms are ruthlessly programmed
- 21:36to trade the noisy, unrevised, and deeply flawed
- 21:40aggregate headline in a fraction of a second,
- 21:43well then, taking three minutes to sit quietly,
- 21:46breathe, and calmly read the composition might
- 21:48just be the greatest structural advantage a human
- 21:51investor has left in the market today. Our slowness
- 21:53really is our edge. Taking the time to wait for
- 21:56the movie's real ending rather than reacting
- 21:58blindly to the spoiler is how you actually understand
- 22:01the story. Thank you so much for joining us on
- 22:04this deep dive. We hope you feel a little more
- 22:06grounded and a little more prepared for the next
- 22:07time the numbers flash across your screen.
