Moody's stock has been performing well, with increases in the current session, over the past month, and over the past year. However, its lower P/E ratio compared to the industry average could suggest that the stock is undervalued, which could be a positive for potential investors. On the other hand, it could also indicate that shareholders do not expect the stock to perform better in the future, which could be a negative. Therefore, the impact on the stock price in the short term is neutral.
