Investment in MRF

Hello everyone, I have recently ( 6 months ago) started stock market trading, and had a pretty decent run, never suffering from a loss. That changed recently when the market crashed, and now it's a buying opportunity. Recently out of curiosity I bought 1stock of MRF. Now it's giving me a 3k loss. Should I invest more in it? Maybe one more stock? I'm hoping people who have been in this game for longer can help me out with it, as I do not have much knowledge about the stock. Here is some information I know 1. Company delivered ROE of 12.46% in year ending Mar 31, 2024 outperforming its 5 year avg. of 8.75%. 2. Stock gave a 3 year return of 63.29% as compared to Nifty 100 which gave a return of 36.45%. (as of last trading session)
