How is alpha calculated?
Alpha measures how much a trade outperformed the S&P 500 over the same holding period. For each politician, we show their dollar-weighted alpha—larger positions count more. A politician with +404% alpha on NVDA means their NVDA trades, weighted by size, beat the market by 404 percentage points.
What does the win rate mean?
Win rate is the percentage of trades that beat the S&P 500. Note that win rate treats all trades equally—a $5K trade counts the same as a $5M trade. This is why some traders show high alpha but moderate win rates (big wins, small losses) or low alpha but high win rates (consistent small wins).
