The decrease in short interest for Rockwell Automation suggests that investors may be less bearish on the stock, which could lead to a short-term increase in its price.

However, the article also cautions that a decrease in short interest does not necessarily mean the stock price will rise, so while the sentiment is more bullish, the impact is not guaranteed.
