Equity Valuations are High, But are They "Too High?"

As common as it is to compare today’s artificial intelligence equity valuations to dot-com bubble levels, there is a reasonable argument to be made that the two periods are not similar, even if market leadership spikes resemble past booms.

Of course, we might also note that each valuation boom “ended” at some point, with valuations normalizing. 


So it is rational to expect a repeat. 


On the other hand, the comparisons might be wrong. 


Forward price-earnings ratios for market leaders are nowhere near internet bubble levels, though that might not be the case for smaller growth names.

The “complication” is earnings growth. So long as that continues, so does the support for valuation.
