> This is the definition of survivorship bias. There are a ton of tech stocks that you would have lost your shirt on had you invested in them just prior to the crash.

Which is why you buy an index, rather than try pick individual stocks.

Buy individual stocks in blue chip companies. The return is always better but if you do buy individual stocks, you have to actually pay attention to that individual company that you invested in does, in short continue to do your homework, in the current bubble, invest in the companies that have great fundamentals (revenue and actual profit) do not invest in those companies where the financials are terrible and have been terrible for years, yet they still command a high price, eventually the party ends.

Currently, there are three companies owned by the same person, the financials and their relative performance/competitiveness is not good despite the oversized hype in comparison to other blue chip companies. But many people have gotten great returns however, it is a don’t get caught holding the bag type of stocks Hint: The three companies are owned by same guy and has a cult like following.
