I think times have changed. When the automotive industry falters, the assets won’t be worth anything near “book value”.
A very wealthy (now retired) investment banker once told me: “The stock market over-reacts, but is right about the general direction”.
Growth potential, margins and inflation drive stock prices.
I don’t see how tech could be anything but a winner. If anything, Corona has accelerated the need for digitization and buying patterns change.
Buffet did horribly during the crisis. He admittedly undervalued Tech and invested in Airlines - big regrets.
I do not think a lot of industries will go back to the way things were. Why travel in planes if you can do zoom meetings? Why your own car when you can work from home?
Personally, I would rather be worried about the real estate market and office buildings folding in value...
