changing sweep accounts

My E*Trade account is currently earning a measly 0.01% interest (in the E*Trade Financial Extended Insurance Sweep Deposit Account).

However I see you can change the sweep account to HTSXX (JPMorgan 100% US Treasury Securities Money Market Fund) which is currently earning a whipping 0.50%.

Here's how to change your sweep account at E*Trade.

In the very top menu on the broker’s website, select ‘Customer Service’. On the next page, click on ‘Self Service’ and then select ‘Change / Update Uninvested Cash Option’ under ‘Cash Management (Deposits, Transfers and Withdrawals)’. Doing so will produce a new page with a drop-down menu of the available core position options. Select the one you want and follow the prompts.

For Schwab customers, I've noticed on their statements that SWVXX (Schwab Value Advantage Money Fund) is now yielding higher than Schwab Cash Reserves (0.90% to 0.67%).  You can't set it up as a sweep account (as far as I know), but you can transfer back and forth from Cash Reserves to SWVXX.  So that's what I've started to do.

For Fidelity customers, earlier this year (2/13/17) I noticed that my CASH in my Fidelity account was getting 0.01% while my Fidelity Government Cash Reserves (FDRXX) in my IRA was getting 0.27%.  (Looking back it had been at 0.01% as recently as February 2016).

I wasn't able to switch my non-IRA account to FDRXX, the options I saw were SPAXX (Fidelity Government Money Market) and FZFXX (Fidelity Treasury Money Market).  Morningstar reported that FZFXX was yielding 0.16% while SPAXX was yielding 0.20%, so I switched it to SPAXX.

[5/18/18 - Looking back at my log on 2/13/17 -- To change the sweep account, go to positions, and click on the current sweep vehicle.  From there you're presented a button to "Change Core Position."  If only it was this easy at the other brokerages.]

Looking at Morningstar, FDRXX is yielding 0.74%, SPAXX is yielding 0.68%, and FZFXX is yielding 0.69%.  I'll stick with SPAXX for now.

I sure wish E*Trade had told me about this months ago.  I had to find out myself.  I looked because both Schwab and Fidelity were giving me much higher rates than E*Trade and TD Ameritrade.  So far I haven't found a good option for TD Ameritrade cash.  So currently I'm sweeping excess cash to Ally Bank savings (currently paying 1.25%).  The disadvantage is that it takes like 3 days for the transaction to complete.
