The increase in short interest for Edwards Lifesciences suggests that investors may be expecting the stock price to decline. However, since the short interest is still below the peer group average, it may not be a strong bearish indicator. The short-term impact on the stock price is uncertain, as short interest is just one of many factors that can influence stock prices. Additionally, some investors may interpret high short interest as a contrarian indicator, potentially leading to a short squeeze if the stock price were to rise unexpectedly.
