Track record of purchases

Not enough time has passed, or price data is missing, to measure these purchases yet.

Change in the stock price from the price paid to the closest weekly price about 1, 3 and 6 months later, from SEC fails-to-deliver data. 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.
