Long term investment strategy (Buy, hold but don’t forget)

Hello Pragnesh
really insightful read. Something I’d like to improve upon are

1. Patience: Patience to hold the stocks / cos and wait for the thesis to play out
2. Behavioural Bias: Ability to hold stocks that are not performing well, instead of switching to the ones that are performing.

However It’s going to be hard to control these behavioural traits. I need to experience different things to build trust in them. On one side I see people using technofunda and investing in quality stocks that are moving up and making good returns with proper risk management. On the other side there are people like you who has guts/stomach to hold stock through downturn and get good returns on the other side.

I’d like to ask your opinion is this regard

1. Have you ever felt you could’ve made better returns by adding technicals to you fundamentals to improve buy or sell decisions ? Or do you just buy and just track them without worrying about what happens in next 3-5 years (your example of alkyl amines, Paushak ) ?
2. I feel all stocks are cyclical at varying degrees like shallo, deep etc. Even if the co. is not cyclical, the market is cyclical in terms of the valuation it assigns to a stock. Some stocks doesn’t give any return for next 5 years (alkyl could be one). So, how do you deal with these situation ? Don’t you sell a stock even if it goes to 100x P/E or 15-20x P/S ? Is there a acceptable level of this exuberance for you ?

Thanks
