By David Russell, reporter at OptionMonsterCOLUMBUS, Ohio ( TheStreet) -- Big Lots ( BIG) has been struggling to break a three-month downtrend, and one bear doubts that it will succeed. OptionMonster's tracking systems detected the purchase of 8,469 January 27.50 puts, mostly for $1.42, and the sale of an equal number of January 25 puts for about 82 cents. Volume was more than 61 times open interest in both strikes. The stock fell 3.83% to $33.39 on Friday, and is down 16% in the last three months. The discount retailer narrowly beat analysts' forecasts the last time it reported earnings on May 27. It also gapped lower on June 22 following a downgrade from JPMorgan, which cited insider selling. The shares attempted to rally back since, but appear to be hitting resistance at their 50-day moving average (red line on chart). Some chart-watchers may consider that as evidence the downward momentum is still in effect. Friday's option trade, known as a bearish put spread, is designed to leverage such a move to the downside. It cost a net 60 cents to implement and will generate a maximum profit of 317% if the stock closes at or below $25 on expiration. The transaction pushed overall options volume in the name to 29 times greater than average. Puts accounted for 98% of the activity. Russell had no positions in the stock mentioned.
