No, you are wrong on both counts.
A company grows revenue and earnings quarter after quarter. The company becomes larger and more valuable. The stock price goes up. That's called fundamentals...
Put 500 stocks like that in an index... the index rises.
Perpetual downtrend???!!!
That makes zero sense.
How are old are you?
You are obviously trading bs stocks like Gamestop, or AMC.
I was using an example of your flawed math. You are wrong about the probabilities of price recovering from $5 to $10. I don't know why you are even talking about fundamentals as that has nothing to do with the discussion. You need to read the first post and understand what the discussion is about. It's not about portfolios, its not about fundamentals, its about a phenomenon called the traders fallacy.
