The reduction in price target by Keybanc suggests that while the analyst remains positive on Sitio Royalties' prospects (hence the Overweight rating), there are factors that may limit the stock's upside potential in the short term. This could be due to a variety of reasons such as market conditions, company performance, or industry trends. Investors may interpret the lower price target as a sign of reduced growth expectations, which could negatively impact the stock price in the short term.
