Analyst ratings, especially from reputable firms like Cantor Fitzgerald, can significantly influence investor sentiment and stock prices in the short term. An Overweight rating suggests that the analyst believes the stock will outperform the average return of the stocks in the analyst's coverage universe. The announcement of a $100 price target, which is likely above the current trading price, indicates an expectation of strong upside potential, which could lead to increased investor interest and a rise in the stock price.
