THE COUCH'S $10,000, DAY BY DAY, REAL DAILY DATA
October 1997. Asian currencies are collapsing. On October 27 the market falls so fast the exchanges halt trading. The next day it has one of its best days in years.
August 1998. Russia defaults. Long-Term Capital Management, a hedge fund run by Nobel laureates, loses almost everything and the Fed organizes a rescue. The market drops 19% by Aug 31, 1998. Every one of these headlines sounded like the start of the next 1929.
None of them were. The couch held through all of it and finished the window with $13,892, +38.9%. The dot-com bubble was still ahead.
Player figures cover every game whose window started in 1997, 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.
16.0% of 1,460 players beat the couch, among the worst human results in the archive. The median player finished -11.1% behind. Two real panics in two years and both were buying opportunities. This window does not punish fear. It punishes acting on it.
