A trend line chart using log price to show that the S&P is still running pretty hot relative to historic trends. There are some good websites that use Mean Reversion Model, exponential fit, and inflation adjusted prices to show the same thing. I did a more visual analysis using trend lines. Hard to know how long price will stay at this level. The recent AI boom has really lifted prices from more moderate levels to very high. Hopefully the strong economy can hold the market up.
