NEW YORK -- Tyson Foods ( TSN) pulled back on Friday after a big rally, and the momentum bulls jumped on board. OptionMonster's tracking programs detected the purchase of about 4,100 April 24 calls for 45 cents and 50 cents. Volume slightly exceeded previous open interest at the strike, indicating that new money was put to work on the long side. Calls lock in the price where investors can buy shares in the meat and poultry company. That will give them significant leverage to the upside if it bounces in the next two weeks, but the contracts will lose most of their value if it doesn't. Tyson shares fell 2.71% to $24.03 on Friday. The stock is up 24% so far this year and is trying to hold support around its February peaks near $24. Earnings are due on May 6 -- after the April options expire -- so the trader is purely betting on a quick bounce. The activity pushed total option volume in the name to six times greater than average in the session. Russell has no positions in TSN.
