Each row links to its Form 4. Since trade compares the stock’s move from the close on the trade date (or the next trading day) to its latest close with the S&P 500 over the same days, adjusted for splits and excluding dividends. It describes the stock, not what the trader made: we don’t know their purchase price, position size or later sales. A dash means the trade isn’t matched to a listed stock, or there is no closing price after it yet.
When several people report on the same filing, we list it under the first one named, so trades by someone usually listed second may be missing here. Information, not investment advice: see the disclaimer.
