    S&P 500 Hits 7,800; Shiller PE Reaches 42, Highest Since Dotcom

    Question

    S&P 500 Hits 7,800; Shiller PE Reaches 42, Highest Since Dotcom

    Direct answer

    With the S&P 500 at 7,800 and a Shiller PE of 42, the market is pricing in a 'perfect' economic outcome. The comparison to the dotcom era is stark, as both periods were driven by transformative technology hype. However, current tech leaders are significantly more profitable than their 2000s counterparts, which may justify a higher floor.
