What happened — and what it teaches
The NASDAQ Composite entered March 2002 under the shadow of the tech bubble's collapse, as regulators moved to restore investor confidence. The Sarbanes-Oxley Act represented the most sweeping overhaul of corporate governance in decades, imposing new accountability standards on public companies. For market participants, the question was how this regulatory revolution would interact with an already fragile market structure.
Between March 15 and October 8, 2002, the NASDAQ Composite fell 39.6%, dropping from 1868.3 to 1129.22 over 144 trading sessions. The index experienced a maximum drawdown of 40.5% and saw individual sessions move as dramatically as 7.8%. Navigating this environment required participants to process regulatory developments against a backdrop of relentless selling pressure, with 25 decision points punctuating the decline—9 of which proved critical to outcomes.
This replay offers a rigorous test of decision-making under regulatory uncertainty. Participants must manage the psychological weight of a sustained drawdown while distinguishing between noise and signal in policy announcements. The episode demonstrates that regulatory change does not follow a linear path, and that disciplined position sizing and emotional control become survival tools when the market moves against you for months on end.
