Most investors skip the simplest piece of self-accountability available to them. They form a thesis, place a trade, and then let time blur the original reasoning into something vaguer and more flattering. Clare Flynn Levy, the former hedge fund manager who founded behavioral analytics firm Essentia Analytics, has a fix for that, and she shared it on a recent episode of the Afford Anything podcast.
Her prescription is almost embarrassingly simple. “When you make the decision, the thing that most people don’t do that they should really do is write down somewhere, I mean, even in your calendar,” she said. Write the thesis. Set a date. Come back and check honestly.
The 529 Trade That Looked Right and Played Out Wrong
Flynn Levy walked through a personal example that any parent saving for college will recognize. After the last election, she moved equity money into bonds in her kids’ 529 accounts, expecting inflation to hurt stocks. She gave the trade a nine-month calendar reminder with specific criteria for revisiting it.
The inflation call was correct. The market reaction defied the playbook. “I was wrong. There was inflation, but that didn’t affect the equity market, interestingly, in the end,” she admitted.
The data backs both halves of that statement. Headline PCE inflation, the Fed’s preferred gauge, ran at 3.5% year over year in March 2026, with core PCE at 3.2%. Both remain comfortably above the Fed’s 2% target. Services inflation has been sticky throughout, sitting at 3.38% year over year in the latest reading. Anyone who said inflation would prove durable was right.
Equities did not care. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY) has returned 29.61% over the past year and 31.44% since November 1, 2024. Bonds, meanwhile, sat on rising yields. The 10-year Treasury yield is at 4.56% as of May 22, 2026, up 0.26 percentage points over the past month, which means bond prices declined for holders of duration. Flynn Levy’s summary was direct: “I missed out on a huge further equity run by doing that. And the bond market hasn’t been particularly good.”
Why the Calendar Reminder Mattered
The discipline is what kept her from compounding the mistake. Because she had written down the thesis and committed to a review date, she could evaluate the position with fresh eyes. By documenting her reasoning, she avoided staying “wedded to the original decision” and could make a fresh choice based on new circumstances.
Consider what else happened during her holding window. The Fed began cutting in September 2025 and has lowered the upper bound of the fed funds target to 3.75% as of May 27, 2026, down from 4.5% a year earlier. Consumer sentiment, meanwhile, collapsed to 49.8 in April 2026, the lowest reading in the past 12 months and well into recessionary territory. The yield curve flattened from a 0.74% peak in February 2026 to 0.49% by May 26 without ever inverting. Every signal that would have screamed “be defensive” coexisted with one of the strongest equity rallies in years.
The 529 Wrinkle
The wrapper amplifies the cost of staying anchored. As the Afford Anything host pointed out, “Assuming that you want the child to go to college immediately after high school with no gap, then it’s an inflexible timeline, right? That, that’s a hard deadline at which point you start making withdrawals.”
Most taxable accounts forgive a bad macro call because time eventually bails you out. A 529 with a teenager attached runs on a fixed clock. Every quarter spent in the wrong asset class is a quarter you cannot recover before tuition bills arrive. The case for writing down the thesis is strongest exactly where the deadline is least negotiable.
The Takeaway
Flynn Levy’s framework works whether “somebody’s advising you” or you are managing the money yourself. Write the thesis. Pick a date. Show up on that date and grade your own work without flinching. You can find the full conversation on the Afford Anything podcast.
Conviction is cheap. Documented conviction with a review date attached is the one discipline that turns a wrong call into a recoverable one.
