Your falling for the same trap as most novice investors - past performance has no predictive value of future performance.

In fact, high performing equities if anything tend to fall and regress to the mean.

Ok, honest question. Have you ever looked at the S&P, say over 50 years? Just simple yes or no.

Yes, have you?

It’s pretty clear high performing company don’t maintain it.

I'm talking about the index.

No, you haven't.

Because if you did, you woulnd't be looking at an exponential and saying "but but but it reverts!!!!"

Please give me an example of a company that has consistently produced annual return higher than the SP500 average over 50+ years (hell, 20+ years).

The answer is there are none. Company tend to have stretches of very high returns, followed by flat or decreasing periods.

So what most people do - buy a stock that has already gone up a lot, are basically buying high and selling low.
