Bearish:

• $SPX - Bearish outlook on S&P 500 returns over the next decade, based on multiple factors including valuation, interest rates, profitability, and economic growth assumptions.

  • “Our conclusion is even if we don't include concentration, we just use some of the other variables I mentioned, valuation, interest rates, profitability, some economic growth assumptions, that would suggest your return profile in the next 10 years is likely to be below average.”

  • “I think that there's one bedrock math fact we know, and that is things that are expensive generally have low subsequent returns. So I would say based on the fact the US stock market is expensive today, that it's gonna have lower returns in the next 10 years compared to the previous 10 years.”

• $TECH - Bearish view on mega-cap tech stocks due to high valuations, with these stocks trading at a negative risk premium and high price-to-earnings ratios not seen in 20 years.

  • “If you look at these leading stocks, they trade today with a negative risk premium. We have not seen that at all for 20 years at 31 times earnings for these companies.”
