What happened — and what it teaches
The S&P 500 entered the final chapter of the dot-com era with technology stocks commanding extraordinary valuations and traditional metrics stretched to historic extremes. Between October 1999 and May 2000, this 142-day replay captures a market that had already surged dramatically but faced mounting questions about sustainability. Twenty-five decision points—nine deemed critical—force participants to navigate a period where momentum and mania coexisted with emerging skepticism.
The index moved from 1281.91 to 1447.8, representing a 12.9% gain over the data span. However, this aggregate gain obscures significant turbulence: a maximum drawdown of 11.2% tested conviction, while the largest single-day swing of 5.8% demonstrated how quickly sentiment could reverse. The period straddled the turn of the decade, covering both the late 1990s boom and the opening months of what would prove to be a transformative—though not yet evident—2000.
This replay trains participants to recognize that during bubble phases, the distinction between skill and fortunate timing blurs dangerously. Managing risk during an 11.2% drawdown requires discipline distinct from ordinary trend-following. The nine critical decision points are designed to expose psychological vulnerabilities: the tendency to overstay positions, to confuse correlation with conviction, and to underestimate tail risks that feel remote until they materialize. Success in this environment demands adherence to process over outcome, making the AI coach's retrospective analysis as valuable as the trading decisions themselves.
