Gronkowski's Winning Play: $69K Apple Stock Investment

NFL legend Rob Gronkowski made his best-ever investment by purchasing $69,000 worth of Apple stock in 2014 on the advice of his contractor. Initially unfamiliar with stocks, Gronkowski forgot about the investment, which more than tripled in value to $250,000 within two and a half years. He sold a portion and retained the rest, which has now grown to over $600,000. Despite his party-boy image, Gronkowski has been financially prudent, living off endorsement deals and investing wisely.
