It's my understanding the S&P is valued at 50 times earnings... a realistic/profitable number is 15 times earnings....
If you are talking about the 12 month trailing P/E of the S&P 500 index, WSJ has it at 18.12 as of 4/6/23, down from 25.57 a year ago.

I think that is because interest rates give people better risk-free alternatives to park their cash and because cash-burning growth companies that need to borrow money at higher rates are much riskier now. Companies that supply stuff that people need are still going to be fine.
