Trader buys 500 30-strike call options for $15 per contract. This $7500 investment gave that trader the right to buy 50,000 shares of Sodastream stock at $30 per share, but it was only trading at $29.50 and the contract expired in 1 day. Within 2 hours an unexpected announcement came that Sodastream was in talks with private investors to go private and the stock price shot up by $5 or $6, and the investor walked away with $250k. Not bad for a single day of trading (assuming it was a legit trade, which is a big assumption right now).
