Sentiment seems to be turning more favorable toward these three stocks, and given new insider buying, shares may be ready to move back higher after losing ground in recent months.

Short selling is a helpful indicator for the market’s sentiment surrounding a stock. When shorting increases, investors are generally more bearish about the stock, and when it decreases, investors are generally more bullish.

We ran a screen on stocks trading near their 52-week lows, searching for those that have seen significant decreases in the number of shares shorted month-over-month. We also screened for those that have seen significant net insider buying over the last six months.

Based on those two factors, these three stocks could be on the cusp of turning back higher.
