Cash is now paying a higher yield in interest than the stock market does in earnings:

The fact that cash now provides a better return on investment suggests a significant change in market dynamics in terms of risk vs. reward. When cash is paying a higher yield than stocks, it means that investors are willing to accept a lower return on their investment in order to have access to their money more quickly. This can be a sign that investors are becoming fearful of a stock market crash.
