For every investor frozen at all-time highs and refusing to buy, BlackRock built a product with them in mind.
Buffer ETFs like the iShares Large Cap Max Buffer June ETF offer investors downside protection and modest upside exposure. The MAXJ ETF uses options to achieve its objective and must be held for the entire "outcome period", typically 1 year, to realize the full benefit of the fund's options. However, with the IVV appreciating considerably since June, I would recommend investors consider the SMAX ETF, which is closer to its hedge level with more upside appreciation room.
