Waiting until the last minute paid off recently for Gaylord Entertainment CFO Mark Fioravanti. The 50-year-old held off exercising more than 32,000 stock options he was granted in 2006 until Wednesday, when they were set to expire. By selling the resulting shares, Fioravanti booked a gain of about $580,000 — about 10 percent more than if he had made his move a week ago, before Gaylord (Ticker: GET) announced it had sidelined activist investor TRT Holdings with a stock buyback plan.
