The increase in short interest for CVS Health suggests that investors are becoming more bearish on the stock. However, the fact that CVS's short interest is still below the peer group average might mitigate the negative impact. The short interest level also provides insight into market sentiment and potential volatility. Given these factors, the short-term impact on CVS's stock price could be negative, but the below-average short interest compared to peers suggests that the bearish sentiment is not as strong as it could be.
