I guess that depends on what you are looking for. The point is, the predictive value for future returns is more important than a new market high. Today we are within the highest 5% of CAPE 10 valuations. Within that range the ten-year S&P 500 return would historically be about 2%. In other words, a purchase today, will only collect dividends between now and 2027. Likely between now and then the index will drop 50-60%.
I consider that much more important information than a new market high. It makes little real difference if the market moves higher and one does not sell. The poor portfolio return is already in the cards you hold.
