<prompt> Human: Prime money fund has a return of 1.72 on SWVXX the investor shares. I know this is historical and subject to change, however does this seem to good to be true or is it safe to put a portion of savings into this account rather then let it sit? Edit: thanks for all the replies. I was trying make sure my thoughts for this short term saving growth were not off. Im very new to this. starting my resiidencyand using this money for a house purchase in the next 9 months  <response>: There are guaranteed safety vehicles like CD that offer 2 for 1 year period. So if you are looking for safety, find a FDIC bank that offers CDs with good rates.
