ATI Inc.
NYSEShort interest in ATI Inc. jumped 42.5% over the past week, reaching 3.76 million shares as of March 31. The surge marks a sharp reversal for the aerospace and defense stock, which has climbed 12% over the past month. Days to cover rose to 1.83, up from 1.43 in mid-March. This indicates short sellers would need nearly two full days of average trading volume to close their positions. The uptick suggests growing bearish sentiment despite the stock's recent price strength. Cost to borrow remains relatively low at 0.32%, though it has ticked up slightly over the past week. Utilization sits at just 0.08%, well below its 52-week high of 1.67%. The minimal utilization shows ample shares remain available to borrow, suggesting the recent short interest increase faces little supply constraint. Options sentiment tilts bullish. The put/call ratio of 0.43 sits below its 20-day average of 0.46, indicating call activity continues to outpace puts. The negative z-score of -1.07 confirms this below-average put buying relative to recent norms. ATI closed Monday at $158.95, down 3.1% on the day but up 12% over the past month. The company reports earnings next Tuesday, April 29. The timing of the short interest spike ahead of the earnings release may signal traders positioning for potential disappointment, though the stock's recent momentum suggests the market remains optimistic. The contrast between rising short interest and strong price performance sets up an interesting dynamic heading into the earnings print. This is not financial advice.
