Given what's been happening in the tech industry and the economy at large, I now keep a 1-year emergency fund in a money-market fund at 4% (Fidelity SPAXX). I'm probably losing out on some growth (SP500 grew 11% over the past year, despite the massive drop in April 2025), but at least I have liquidity in case I get laid off.
That's the kind of game I feel I have to play these days.
