In my early investing days, I did all the wrong things. I bought what I knew (AAPL). I bought and held. The one good thing I did was inadvertently average down. When my AAPL went down, I said “I still believe in the stock” and bought some more. Then I forgot about it.
One day I noticed that AAPL was trading at $500. With splits over the years, my basis was about $9. Even a blind squirrel finds a nut, now and then.
