A University of Chicago study randomized hedge fund sell decisions and found random selling outperformed manager-selected selling by 150–200 basis points. Buys are analytical; sells are emotional — the solution is to make fewer decisions.
Where this was said

This chapter delivers the episode's most memorable statistical one-two punch. First, Ritholtz cites behavioral research showing roughly one-third of investors who panic-sold during a major market crash — he uses the 2008-09 57% decline as the reference — never re-entered equities. [1] — Barry Ritholtz "About one-third of investors who panic-sold during the 2008-09 market crash never returned to equities. A $1 million portfolio sold at the …" 13:57 The arithmetic is brutal: a million-dollar portfolio sold at the bottom exits at around $450K; the same portfolio held through the recovery would be worth roughly $4.5 million today. No money market rate comes close to competing with that compounding. Then Shaan Puri raises the hedge fund study, and Ritholtz goes deep on the Alex Imas University of Chicago research that randomized sell decisions. [2] — Barry Ritholtz "A University of Chicago study randomized hedge fund sell decisions and found random selling outperformed manager-selected selling by 150–20…" 15:05 The finding: randomly selling anything else in the portfolio outperformed the manager's deliberate choice by 150–200 basis points. The explanation is elegant — buys are spreadsheet-driven and rational; sells are always emotional. The solution, Ritholtz concludes, is not to get smarter about selling, but to make fewer decisions altogether.
About a third of investors who panic-sold during market crashes like 2008-09 never returned to equities, missing a 10x recovery over the following 15 years.
About one-third of investors who panic-sold during the 2008-09 market crash never returned to equities. A $1 million portfolio sold at the 57% bottom would have exited at ~$450K; staying put would have produced roughly $4.5 million today.
An investor who sold at the bottom of the 2008-09 57% crash and never re-entered would have exited with ~$450K; staying invested would have grown the same million to roughly $4.5 million.
A University of Chicago study found that randomly selling any other stock in a hedge fund manager's portfolio outperformed the manager's chosen sell by 150 to 200 basis points, proving sell decisions are driven by emotion.
Sam built Algrow, a SaaS for finding viral content formats, with zero coding experience using ChatGPT and Cursor. Six months later: 10,000 users, $14K/month in revenue.
Sam's first MVP threw an application error on its very first user — and he shipped it anyway. The core idea worked, and that was enough to validate the product and keep users coming back.
Sam joined Discord voice chats, muted himself, and silently screen-shared his product. Users in the chat started tagging him asking what the tool was. No pitch needed — curiosity did the selling.
Most founders post links in Discord and immediately get banned for self-promotion. Sam's approach was the opposite: build rapport, help people with the tool, let word of mouth do the work.
Find where your ICP lives. Listen before building. Validate with DMs and Loom recordings. Build in public with users inside your own Discord server. Turn early adopters into advocates with free access.
Instead of fearing the self-promo ban in large Discord servers, create your own private server for your product. You funnel in ideal customers and build a relationship that email can't replicate.
Algrow helps creators find and replicate viral video formats, starting at $25/month. It analyzes subscriber counts, average views, and trending formats — and can even generate the videos with AI.
After weeks of Sam silently screen-sharing in a Discord server, the server owner — unprompted — made a full YouTube promotional video about Algrow. Sam paid nothing and asked for nothing.
Producer Gus admits Discord never crossed his mind as a customer acquisition channel. Pat connects the insight to a broader lesson: match your distribution channel to where your actual customers live.
