No one can accurately predict a stock market crash — this is the most realistic answer.

Experts have been calling for a crash for several years, but the S&P 500 still continues to hit new highs, even though P/E and CAPE valuations are already high.
A crash is essentially unpredictable and usually results from unexpected events.
Instead of fantasizing about timing the top, it's better to focus on long-term diversified investing and adopt an irregular TP (Take Profit) strategy, taking profits in stages, locking in some gains, and managing risks well.
The market remains irrational for a period often much longer than we expect!📈
