I despise target retirement age funds for exactly this reason and I have all my 401k funding in major index funds that I do not care about beyond that on a day to day basis.
The major target retirement date funds are just "funds of funds" that are distributed across stock and bond index funds in an age appropriate allocation. e.g. https://investor.vanguard.com/investment-products/mutual-fun... They're generally not actively managed funds chasing bubbles.
