Analyst upgrades typically have a positive impact on the stock price as they indicate a more favorable outlook for the company. In this case, Broadridge Financial Soln has been upgraded from Underperform to Peer Perform by Wolfe Research, which suggests that the analyst now believes the company's stock will perform in line with its peers, rather than underperforming. This could lead to increased investor confidence and a potential rise in the stock price in the short term.
