Mbia Inc insider trading
Every open-market purchase and sale by Mbia Inc's officers, directors and largest shareholders since November 4, 2021, and what the share price did next.
Does following Mbia Inc’s insiders pay?
From August 26, 2010 to August 28, 2025, 16 insiders reported 22 open-market purchases and 37 sales not made under a pre-set plan in Mbia Inc. Twelve months after each purchase was reported, the shares were +1.9% against the S&P 500 on average (median +4.9%), over 22 purchases with a full year of prices; 64% beat the index. After sales, the shares moved −10.3% 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 27, 2010 into $25,603 by November 2, 2026, +6.0% a year. It held shares 42% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $28,328 (+6.7% a year), and held throughout $94,254 (+14.9%).
