$SOFI calls trade up

SoFi (SOFI) rose sharply today, rewarding upside call positions opened two weeks ago.

On Apr. 17, Market Rebellion’s Unusual Option Activity Service found that 70,000 May $13 calls were bought for $0.35 to $0.42 with shares at $10.95. This was clearly fresh buying, as open interest in the contract was just 7,584 before the activity appeared.

Those calls have traded for as much as $1.87 today, a 345.24% gain, while the stock rose 32.24% in the same time frame, a large move but nothing like that of its options on a relative basis.

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.

SOFI was last at $13.44, up 1.86% on the session.
