The answer is quite simple. Why do people make a mystery out of this.

If today you buy an orange for long term because you expect it to appreciate over time maybe years.

4 months later the market offers you 50% higher price.....wouldn't you take it instead of waiting ...? A bird at hand is worth 2 in the bushes.

When Buffett says if is long term means he is patient to wait for prices to move higher it make take years ...but if overnight it moves to overvalued prices he will sell.

The recent rally was a massive 50% deadcat bounce for TSMC. It is smart to take the money off the table and be done with it.

Don’t think Buffet will sell within one quarter for a fractional profit. It simply go against his life long philosophy. 
Likely the geopolitical risk has risen too much
