How do you actually execute that without bleeding money though? TBH I haven't touched US ETFs in a few years after EU forbade me from trading them, so I'm not up-to-date on the most recent products.
I would sit on the cash, miss the first confirmation of a top (but of course take notice) then build shorts on short term spikes to the upside unless the market meaningfully reverts and negates the initial top.

You can scan mutual funds and you will find some 5 star safe ones giving 5%. Personally I will sell SPY 40% to 50% out of the money PUTs for one year from now. I will do this trade in 5 steps each with 3 weeks from each other.

Nexo is a registered financial institution. They provide asset secured lending with rates from 8% to 12%. You can also buy Bitcoin and sell futures against it. Returns range from 8-12%. Positions have to be managed based on big moves, but if you hedge properly, then futures sales against spot create a time-delayed arbitrage. Obviously, you need to pick the best crypto site. Binance is the most credible. You can do this on conventional markets, but it's much trickier because you can't hedge with spot Bitcoin against the future. This forces you to maintain two pools of capital, cutting returns in half.
