Analyst ratings, especially from reputable firms like Wedbush, can significantly influence investor sentiment and stock prices. An Outperform rating suggests that the analyst believes IMNM will perform better than the market or its sector, which could lead to increased investor interest and a potential rise in the stock price in the short term. The announcement of a price target of $12, which is presumably higher than the current trading price, further underscores the analyst's bullish stance on the stock.
