There's something horribly buggy about VMFXX going on (Money Market fund).
Looks like a good website, but I'd like VMFXX to represent how "money markets" would have done over these timelines!
VUSXX (Vanguard's "other" money market fund) is closer to what I expected, but seems to be missing all the dividends/interest rates entirely.

For money market funds, it could be that daily-dividends are something that your code wasn't expecting and is bugging out on?
- compumike 4y agoGood catch, thank you! I've investigated and it appears that the data comes in already completely buggy from my upstream data provider, https://eodhistoricaldata.com/ https://eodhistoricaldata.com/ . I will open a support ticket with them! In the meantime, perhaps you can use one of these symbols instead: https://totalrealreturns.com/s/MUB,BSV,SHY,VGSH,SCHO,FLTB https://totalrealreturns.com/s/MUB,BSV,SHY,VGSH,SCHO,FLTB
- dragontamer 4y agoI used BIL as my proxy for MMFs Even very conservative funds like SHY aren't quite like a MMF. BIL is very close though. We can see that SHY is negative for the year, while BIL (and "proper" MMFs like VMFXX / VUSXX / etc. etc.) are all positive / better than cash under a mattress. https://totalrealreturns.com/s/SHY,BIL,USDOLLAR https://totalrealreturns.com/s/SHY,BIL,USDOLLAR I'd argue that when most Bogleheads talk about "cash", they're talking about BIL and MMFs. Something between 0 months to 3-months of maturity. ----- I'd still like to see MMFs working of course. I'm sure there's a minor difference between BIL and VMFXX that I haven't though of... but BIL is the closest thing I can think of to a money-market fund.
- compumike 4y agoPerfect, thanks. Shorter duration like BIL makes sense. Ticket filed with upstream data provider... we'll see.
