Does following Transocean Ltd.’s insiders pay?
From March 3, 2010 to July 7, 2026, 22 insiders reported 58 open-market purchases and 24 sales not made under a pre-set plan in Transocean Ltd. Twelve months after each purchase was reported, the shares were −44.5% against the S&P 500 on average (median −61.5%), over 24 purchases with a full year of prices; 8% beat the index. After sales, the shares moved −45.7% 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 24, 2011 into $734 by November 2, 2026, −15.8% a year. It held shares 57% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $31,430 (+7.8% a year), and held throughout $83,621 (+15.0%).

Months when 2 or more insiders became net buyers, or 3 or more net sellers, of Transocean Ltd. 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.
