From insiders' Form 4 filings with the SEC: open-market purchases and sales only (awards, option exercises and shares withheld for tax are excluded), combined to one line per insider per day. "Plan" marks trades the filing says were made under a pre-set Rule 10b5-1 trading plan, which are scheduled in advance. Price changes run from the close on the trade date; hover a figure for the change relative to the S&P 500. Past moves don't predict future ones.

Moves are the shares’ return including dividends minus the S&P 500’s, from the close on the first trading day after each report; the number of trades with a finished 12-month window is in brackets. Green means the trade went the insider’s way (a purchase ahead of the index, a sale followed by the shares trailing it). A trade reported both by a director or officer and by a fund or company they are linked to counts once here, under the person. Purchases count only where the share price actually traded was at least $5. These figures describe what the shares did, not why anyone traded. Insiders across all companies.

When several insiders traded Data I/o Corp

Months when 2 or more insiders became net buyers, or 3 or more net sellers, of Data I/o Corp in reports dated in the 91 days before the month end, and how the stock did against the S&P 500 from that month end. After 1 selling crowd, −49.2%. One company's history is too short to judge by; the test across every company is the better guide.

Month	Crowd	3 months on, vs S&P 500	6 months	12 months
November 30, 2017	5 selling	−38.2%	−49.2%	−67.8%
