Bullish options traders collected exponential profits in Activision Blizzard Inc. (ATVI - Get Report) , only one session after opening their positions.

On Monday, September 10, Investitute's tracking systems detected the purchase of 5,000 September $75 calls for $0.86 to $1.10 with shares at $73.91. This was clearly fresh buying, as volume was well above the strike's open interest of 2,662 contracts.

These investors likely wanted to game the shares of ATVI, playing for upside in the stock price while limiting their downside risk, should their analysis that the company's products outperform expectations with beta trials leading into the holiday season.

Those September $75 calls sold for $4.90 just before the closing bell Tuesday, more than five times their initial purchase price. The stock rose 7.56% at the same time, showing how quickly options can far outperform their underlying shares.

Long calls lock in the price where investors can buy a stock, letting them position for a rally at limited cost with the potential for significant leverage. They carry less risk than owning shares because the most that can be lost is the price of the options no matter how far the stock might fall.

Activision Blizzard jumped 7.06% to $79.50 on September 11. The game developer rallied after releasing a beta version of "Call of Duty: Black Ops 4" for the PlayStation featuring a "battle royale" mode designed to compete with the popularity of "Fortnite."
