- Lucas: You've done the math. You've saved 25 times your annual spending, you're going to withdraw four percent a year, you're golden. Except you might not be. Because the one variable nobody can control is the order in which your returns arrive. Luna: And that's the whole problem. sequence of returns risk. It's not about the average return over 30 years — it's about whether the bad returns hit early or late. Lucas: Exactly. If you retire right before a market crash and you're pulling four percent out every year, your portfolio can get decimated even if the market eventually recovers. You're selling shares when they're cheap, locking in losses. And the math shows that two retirees with identical average annual returns can have wildly different outcomes just because of timing. Luna: It's one of those things that sounds obvious once you hear it, but most people don't think about it when they're planning. They just assume a steady 7% a year and call it a day. Lucas: Right. And that assumption is dangerous. So let's be concrete. Let's take two hypothetical retirees — let's call them Alice and Bob. Both have a million-dollar portfolio. Both plan to withdraw $40,000 a year, adjusted for inflation. Both get the exact same sequence of returns over 30 years — 10 years of good returns, 10 years of mediocre returns, 10 years of bad returns. Luna: But they get them in different orders. Lucas: Exactly. Alice retires into a bull market. Her first 10 years are the good ones — say 15% annual returns. Then she gets 10 years of 5% returns, then 10 years of negative 5% returns. Bob retires into a bear market. He gets the bad returns first — negative 5% for the first 10 years. Then mediocre, then good. Luna: And the ending balances are not even close. Lucas: They're in completely different galaxies. Alice ends up with over two million dollars at the end of 30 years. Bob runs out of money in year 22. Same average return over the full period — I calculated it, both have an average annualized return of about 4.8% — but Bob is broke eight years before the end. Luna: And that's the thing. The average return didn't save him. It's the sequence. Lucas: And this is why, if our conversations about retirement math have made you think more carefully about your own plan, I want to mention something. We keep this show ad-free and independent, and the reason we can do that is listeners who find value in it and want to support it. It's not a big ask — a couple of dollars a month is genuinely what keeps these going. If that's something you've gotten out of the show, you can head over to buy me a coffee dot com slash fexingo. No pressure at all. Luna: Yeah, it really does make a difference. And it lets us keep diving into these topics without any sponsor interference. So thank you to anyone who's already done that. Lucas: Alright, back to the math. So Bob's case is the nightmare scenario. But it's also preventable. You don't have to just accept sequence risk. There are concrete strategies to hedge against it. Luna: What's the simplest one? Lucas: A cash buffer. You keep one to two years of living expenses in cash or very short-term bonds. When the market drops, you don't sell stocks — you spend from the cash buffer. You give the portfolio time to recover before you start selling again. The research shows that even a one-year cash buffer dramatically reduces failure rates. Luna: So you're essentially building a small moat around your portfolio. Lucas: Exactly. And you refill the buffer during good years. It's not complicated, but it requires discipline. The second strategy is flexible spending. Instead of mechanically withdrawing four percent every year regardless, you cut back in down years. Even a small reduction — say 10% less when the market is down 20% — has a huge impact on longevity. Luna: That's harder to do emotionally, though. Especially if you've already planned your lifestyle around a certain spending level. Lucas: No question. But it's worth it. There's a famous study by the folks at Morningstar — they looked at what they call a 'dynamic spending rule.' Basically, you increase spending with inflation except when the portfolio drops more than 10%, in which case you skip the inflation adjustment. That one tweak cut the failure rate by more than half. Luna: That's a pretty painless adjustment. You're still spending the same dollar amount — you just don't give yourself a raise that year. Lucas: Right. And the third big one is the bucket strategy. You divide your portfolio into three buckets. Bucket one is cash and short-term bonds — covers years one through three of withdrawals. Bucket two is intermediate bonds — years four through seven. Bucket three is stocks — everything beyond. You spend from bucket one, refill it from bucket two when it runs low, and only tap bucket three if necessary. It's a way of mentally and mechanically separating your short-term spending from your long-term growth. Luna: And that keeps you from panic-selling stocks when the market tanks, because you've already set aside the money you'll need for the next few years. Lucas: Exactly. And it works. The research from Wade Pfau and others shows that a bucket strategy can significantly improve withdrawal sustainability. But it's not perfect — you have to be disciplined about rebalancing, and you need to accept that the cash bucket drags down your overall returns. Luna: So it's a trade-off. You sacrifice some upside for safety. Lucas: Right. But in the context of sequence risk, that trade-off is almost always worth it. Because the alternative — running out of money at age 82 — is much worse. Luna: I want to go back to the cash buffer idea for a second. How big should it be? I've seen different numbers. Lucas: It depends on your risk tolerance and your withdrawal rate. For someone withdrawing 4%, one year of expenses — so $40,000 on a million-dollar portfolio — is a good starting point. Two years is more conservative. The thing to remember is that the buffer doesn't earn much, so you don't want it too big. But you also don't want it too small. Luna: And you refill it when the market is up. Lucas: Right. One approach is to set a threshold: when your portfolio is up more than 10% in a year, you take half the gain and add it to the cash buffer until it's back to the target. That's a simple rule that works. Luna: So it's almost like a mini version of rebalancing. Lucas: Exactly. And it ties into the broader idea of having a plan for sequence risk, not just hoping it doesn't happen to you. Luna: So if someone is listening and they're five years from retirement, what's the one thing you'd tell them to do today? Lucas: Start building that cash buffer. And think about your spending flexibility. Even if you don't think you'll ever cut spending, just knowing that you could if you had to is powerful. And run your numbers through a Monte Carlo simulator that explicitly models sequence risk. There are free ones online. Most people are shocked when they see the range of outcomes. Luna: It's sobering. But better to be sobered now than broke later. Lucas: Exactly. Sequence risk is the silent killer of early retirement plans. But it's also one of the most manageable risks if you know it's coming.
