Meanwhile short sellers have covered positions in Lindsay Corp, a previous most shorted stock. Short interest has declined to just under one quarter of shares outstanding on loan. While still remaining heavily shorted, the irrigation system provider's shares have fallen 4.7% year to date as its earnings have continued to deteriorate.

Short sellers have continued to build up positions in used car business Carmax. Short interest has climbed higher to 22.3% in the past 12 months while shares in the company have fallen by one third. Shorts continue to target the firm as growth falls short of expectations, despite the firm posting sales and earnings growth.
