>e.g. sitting in cash

I read somewhere (but didn't do my own research) Schwab's business model these days, maybe others, is making money off idle customer cash, now that they don't charge trading commissions. They may not want customers to buy anything.

With interest rates up so much, I would guess it is even more lucrative?

With VMRXX giving a YTD compound yield of 5.41% ( https://investor.vanguard.com/investment-products/mutual-fun... ), I've actually been happy to have parked a bunch of cash and not touched it.

It isn't going to compound though, at least that's what long term rates imply.
