Hello, investors! I would like to ask you under what circumstances you are reassessing your investment thesis. Suppose the stock XYZ that you have in your portfolio has fallen significantly - you overbought. Then, for the next few months, it keeps falling - you overbought... When does the moment come for you when you tell yourself that you're not actually buying the dip anymore, but you're sinking more and more money?
Certainly when fundamentals change, there are poor results, margins fall and competitive advantage is lost. Simply put, when a company's fiancials deteriorate.
Results and management are very important. Unless the results are significantly worse and there is a reasonable CEO, I still buy.
If I don't like the political situation (China) then maybe the loss of competitive advantage (Intel), I find I have no better info than the market and the sector is opaque to me (pharma). There are many more reasons and I will probably end up with only one ETF later on from the few companies I have now:)
