A decrease in short interest typically suggests that investors are becoming more bullish on a stock, expecting its price to increase. For AEHR, this could mean a short-term positive impact on its stock price, especially since the decrease is significant. However, the fact that AEHR's short interest is still much higher than its peers' average indicates that there is still a considerable bearish sentiment, which might temper the potential upside. The confidence in this analysis is based on the reported data and the general market interpretation of short interest levels.
