Buffett has a long history of staying away from tech stocks. He looks for stocks with moats, paying dividends... It is his philosophy and he has an army of followers. It has been working well with low interest that forces investors to look for these stocks.

bought the falling IBM. He missed all the small high tech companies that
have been doing great. To his credit, he escaped the internet mirage.
I described his weaknesses and strengths in this blog.
