There is no such thing as risk in a diversified portfolio if you buy the bottom. What is the bottom. The bottom is your entry. Once you are in, you have 2 options, average down once or twice, or just go all in. All in doesn’t mean 100% of your capital. All in means 100% of the capital allocated for 1 stock in your diversified portfolio. Then don’t sell the thing. If it goes to zero, it goes to zero. Just don’t spend all your money on one thing no matter how good the potential or how undervalued the stock may be. When something is 99% down. You MUST go in with or without research. And don’t look at the stock. Ignore the short term volatility. If you are extremely confident in a stock that is 99% down, maybe invest 2000 instead of your usual 1000 allocation per stock. Now there is only one stock I am confident to put all my money in one basket. That stock is ZMM. But I am not all in ZMM. I buy some MMI, I buy some FGO, I buy some MRG etc. And I see you next year.
