Latest / Bull Market Conversations with Fexingo: Rallies, Momentum, and Riding Market Strength / Why Record Profit Margins Are Fueling This Bull Market
Transcript
- Lucas: So there's a chart that's been making the rounds this week, and it might be the single best explanation for why this bull market keeps grinding higher. Corporate profit margins are at the highest level on record. Not just for tech — across the entire S&P 500. Luna: I saw that. It's almost counterintuitive when you look at the GDP numbers. Real GDP growth slowed to one point five percent annualized in the latest quarter, but margins are still expanding. Lucas: Exactly. And that divergence is the story. Nominal GDP is actually still growing at a healthy clip — it's up to thirty-two point four trillion dollars. But real growth is being dragged down by the inflation adjustment. Companies are holding pricing power, and their input costs aren't rising as fast as they were a year ago. So you get this margin tailwind even as the economy cools. Luna: So the market is effectively rewarding companies that can protect profitability in a slower growth environment. That's why we're seeing the S&P up zero point four percent over the past week while the Dow is down half a percent. Lucas: Right. The Dow is heavy on industrial and cyclical names that are more sensitive to the real economy. The S&P is boosted by tech and other high-margin sectors. And the Russell 2000 is up one point five percent in five days — small caps are actually leading here, which is interesting because they're usually the first to feel a slowdown. Luna: Small caps with margin resilience? That's a powerful combination. It suggests the earnings picture isn't as fragile as the GDP print might suggest. Lucas: And that's the key insight. Wall Street analysts have been revising profit forecasts upward even as they trim GDP estimates. The market is pricing for margin persistence, not just top-line growth. That's why you see companies like Cloudflare up three point two percent over the past week while CrowdStrike is down two point nine percent — it's not about the sector, it's about who can sustain margins. Luna: So what's driving this margin expansion? Is it pricing power, cost cutting, or something else? Lucas: It's a mix, but I'd say the biggest factor is that companies have been through two years of inflation shock. They've learned how to run leaner. They've renegotiated supply contracts, they've automated more aggressively, and they've been disciplined about headcount. Now that input costs are stabilizing, all that efficiency falls straight to the bottom line. Luna: That's the 'higher for longer' narrative applied to margins, not rates. And it makes sense why the Fed can hold rates at three point six three percent without derailing the bull market. Lucas: Precisely. The Fed funds rate being flat at three point six three percent is actually a sign of stability. The market isn't pricing in aggressive cuts because it doesn't need them. As long as profits hold up, equities can tolerate a higher cost of capital. Luna: But there's a risk. If margins are at a record, the next move is usually mean reversion. What happens when pricing power fades? Lucas: That's the million-dollar question. And it's why you're seeing such a divergence in investor sentiment right now. Bill Ackman just bought Netflix again, saying it's won the streaming wars. He's betting on a company with subscription pricing power and expanding margins. On the other side, Steve Eisman is flagging an Achilles' heel in the AI boom — he's worried about the capex cycle and whether those investments will actually generate returns. Luna: So you have two very smart investors looking at the same market and coming to opposite conclusions. Lucas: And both can be right, because this bull market is increasingly selective. It's not a rising tide that lifts all boats. It's a market that rewards companies with demonstrated margin resilience and punishes those that can't deliver. Look at Shopify down zero point six percent over the past week while Palantir is up zero point eight percent — both are growth names, but the market is differentiating on profitability. Luna: That's a good point. So for the average investor, does this mean you should focus on quality metrics like return on equity and operating margin rather than chasing the hottest sector? Lucas: I think that's exactly right. In this phase of the bull market, the easy money from multiple expansion is behind us. The gains are coming from earnings growth, and specifically from margin expansion. If you're looking at a stock, ask yourself: can this company sustain its margins if growth slows to one percent? If the answer is yes, it's probably a better bet than a company that's already at peak efficiency. Luna: And that's why we're seeing small caps outperform this week. The Russell 2000 is up one point five percent, and those companies have more room for margin improvement than the mega-caps. Lucas: Exactly. Large-cap tech has already been optimized to death. The margin expansion story is now playing out in mid-caps and small-caps where there's still operational leverage. That's a meaningful rotation, and it's one of the reasons the breadth of this bull market is broader than people think. Luna: So if margins are the new king, what should we be watching as a warning sign? Lucas: The first thing is wage growth. If labor costs start accelerating faster than productivity, margins will compress. The second is input costs — commodity prices, shipping costs, anything that hits the cost side. And the third is the tone of earnings calls. If management teams start talking about needing to reinvest more or compete on price, that's a red flag. Luna: And what about the AI angle? Eisman's concern is that the capex cycle is going to destroy margins before we see the payoff. Lucas: That's a real risk, especially for companies building massive data centers. The depreciation alone can eat into margins for years. But the flip side is that AI is also creating efficiencies — automating customer service, optimizing supply chains, writing code. So it's a double-edged sword. The companies that figure out how to use AI to cut costs will see margins expand even further. The ones that just pour money into capex without a clear ROI will get hurt. Luna: It's like the early internet all over again. Some companies spent billions on fiber and never made a dime. Others figured out how to use the web to sell products more efficiently. Lucas: Right. And that's the lens I'd use for any stock right now: is this company using technology to improve its margins, or is it just spending to keep up? The market is paying a premium for the former and discounting the latter. That's why you see Cloudflare up three point two percent — they're seen as a company that can monetize its network efficiently — while CrowdStrike, a great company but one with high sales costs, is down two point nine percent. Luna: So the bottom line is: margins are the new multiple. The market is willing to pay up for companies that can prove they can hold or expand profitability. Lucas: And that's the most useful takeaway for listeners. When you're evaluating a stock, don't just look at revenue growth. Look at the trajectory of operating margin over the last four quarters. If it's expanding, that's a signal that the company has pricing power and cost discipline. If it's contracting, even a strong top line won't save you in this market. Luna: That's a practical metric anyone can check. I think that's the kind of insight that makes this show worth supporting. Lucas: Absolutely. If our money conversations have helped you think about investing differently — whether it's understanding margins or just asking better questions about a stock — and you want to keep the show free and independent, you can support us at buy me a coffee dot com slash fexingo. It's an easy way to keep the conversation going. Luna: And every bit helps, honestly. But back to margins — I want to dig into one more thing. How do you actually spot a company that's early in margin expansion versus one that's already maxed out? Lucas: Good question. Look for companies that have recently invested in automation or digitization and are just starting to see the payoff. Typically you'll see revenue growth slowing slightly, but operating income growing faster. That's the sweet spot. Also, check the free cash flow margin — if it's improving faster than the operating margin, that's a sign of working capital efficiency, which is another underappreciated lever. Luna: So it's not just about the income statement, but the cash flow statement too. Lucas: Exactly. And that's what separates the durable margin stories from the one-hit wonders. In this bull market, cash flow is king. The S&P can keep hitting new highs as long as companies are converting earnings into cash. And with margins at record levels, that cash generation is fueling buybacks, dividends, and reinvestment — all of which support higher stock prices. Luna: It's a virtuous cycle. And as long as the Fed stays put and inflation doesn't spike again, it can keep going. Lucas: Right. The risk would be a sudden spike in input costs or a wage shock that catches CFOs off guard. But for now, the evidence is on the side of the bulls. The GDP data might be soft, but the profit data is strong. And in a market that's increasingly selective, that's the signal to follow. Luna: So the next time you see a headline about slowing GDP, remember that what really matters is what companies earn per share — and right now, margins are telling you the bull market still has legs. Lucas: Couldn't have said it better. That's the takeaway for today. Keep an eye on margins, keep an eye on cash flow, and you'll be better positioned than most.
