I think their point is that businesses at the top of the S&P500 are traded at sentiment and momentum based values that are pretty disconnected from a logical P/E, which is valid enough. The multiple happens to be 10x in Tesla's case, it's not 10x for all of them (in the case of Saudi Aramco it's probably less than 1x), but it's much less of an informed valuation than the sheer volume of trading would make you think.
