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.

Does following Suncoke Energy, Inc.’s insiders pay?

From August 9, 2011 to March 2, 2026, 22 insiders reported 37 open-market purchases and 28 sales not made under a pre-set plan in Suncoke Energy, Inc. Twelve months after each purchase was reported, the shares were −15.7% against the S&P 500 on average (median −6.1%), over 24 purchases with a full year of prices; 42% beat the index. After sales, the shares moved −5.0% against the index over 12 months (a negative figure means selling was the right call). Buying each purchase the day after it was reported, an equal amount each, held 12 months or until that insider reported a sale, would have turned $10,000 on August 10, 2011 into $20,409 by November 2, 2026, +4.8% a year. It held shares 72% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $51,437 (+11.4% a year), and held throughout $87,932 (+15.4%).

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 Suncoke Energy, Inc.

Months when 2 or more insiders became net buyers, or 3 or more net sellers, of Suncoke Energy, Inc. 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 the 7 buying crowds with six months of prices, it averaged −5.9% against the index. After 2 selling crowds, +4.9%. One company's history is too short to judge by; the test across every company is the better guide.
