THE COUCH'S $10,000, DAY BY DAY, REAL DAILY DATA
January 1965. The go-go funds are buying glamour stocks and turning them over every few months. Conglomerates are the hot idea. The market is at a record and the managers running it are on magazine covers.
Then 1966. Inflation picks up, the Fed tightens, credit gets scarce, and the market drops 20% by Oct 7, 1966. Two years after it sat down, the couch has $10,119, a return of +1.2%. Plain T-bills earned +9.0%. For once the boring option beat the boring option.
This is a flat window with a scare at the end. The kind of market where everybody trading feels clever, and the scoreboard says a tie.
Player figures cover every game whose window started in 1965, not only the exact hand above, and come from the run export of October 31, 2026. A win counts as SKILL only if it beats 90% of 1,000 monkeys replaying the same window with the same trade count and the same time in the market. Across the thirty windows in this archive players beat the couch 39.2% of the time, because these are the famous years. Across the whole ledger the couch wins 62% of 120,800 games.
47.5% of 1,514 players beat the couch, about a coin flip, with 6.8% passing the monkey audit. In a market that goes nowhere, cash costs almost nothing, so timers lose little and win a lot of close calls. That is not skill showing up. That is the price of being wrong dropping to zero.
