Choosing stocks for investing in a portfolio needs to be chosen wisely

"Choose your friends wisely, and also choose friends that you can trust."-Elyn Saks Choosing stocks for investing in a portfolio also needs to be chosen wisely. Recently, I came across two stocks that had no previous corporate governance issues but their pricing behavior made be suspicious and I exited those two stocks. Some time back SEBI chief had raised concern on froth in small and midcap stocks after that many stocks corrected but This particular stock from energy sector hit the lower circuit. Although most of the stocks had corrected at that point of time, the stock hitting the lower circuit raised questions in my mind. Another stock from pharma sector I noticed was hitting lower circuit on multiple days consecutively while the overall market was hitting all time high.  One more stock from Internet sector. Periodically it keeps appearing in the bulk deals and block deals report. I noticed that the buyer and seller happens to be from same family and it looked like it was an attempt to show high volume in the stock to attract buyers. I exited the stock.

I suspected operator game in the stocks and blacklisted the stocks and their parent/ sister concerns from my radar.
