Change in the stock price from the price paid to the closest weekly price about 1 week, 1 month, 3 months, 6 months and 1 year later, from SEC fails-to-deliver data. "Vs. S&P 500" subtracts the change in the SPY ETF over the same weeks. Dividends are not included, and purchases with a possible stock split in between are skipped. Past results do not predict future ones. How we measure this

Names come from the filings. Different people can share a name, so we group trades by the SEC's reporting-owner number (CIK) instead.
