S&P 500 Megaphone Pattern - 50 Percent Potential Dip

I am bullish long term but wouldn't be surprised if we had a correction that rivals 2020, 2008, & 2000. Looks like a megaphone pattern. Currently, I am sitting about 50% cash, ready to deploy on the correction. If you disagree then ask yourself why big players like Warren Buffett or Dr. Burry are selling large positions or in Michael Burry's situation, putting a $500M short on Tesla? Let's hope I am wrong but I have to be honest with myself considering we are in a phase of euphoria and the FED is just fanning the flame with their MMP. What are your thoughts? Am I the only one that sees this?
