$MSOS call prices light up

Bullish option traders are scoring big gains in calls on the AdvisorShares Pure US Cannabis ETF (MSOS) today.

On Apr. 12, Market Rebellion’s Unusual Option Activity Service found that 9,000 Weekly $10 calls, expiring May 10, were bought for $0.60 with shares at $8.71. This was clearly fresh buying, as open interest in the contract was just 359 before the activity appeared.

Those calls have changed hands for as much as $2.00 this session, a 233.33% return, while the stock rose 24.91% in the same time frame, illustrating the kind of leverage that can be achieved with options.

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.

MSOS was last up by 20.95% at $10.91 this afternoon.
