Important Investment Lessons I Learned this Month for Banking Stocks

Long story short, I made a mistake by not entering into banking stocks 2 weeks ago. I have previously stated an entry strategy for Malaysian banking stocks here, and was in the opinion that they were undervalued and had the opportunity to go higher. This is probably the best thing that happened to help me learn about how to invest. I am really not interested in talking about investments I got right, cause there really is nothing to learn from it. I am more interested in the investments I got wrong.
