Investment Q&A

Q: I submit this question again since it did not seem to go through, sorry if is doubled .I intend to invest cash very progressively in 2025 ,since I consider as ''not totally impossible'' that (among other world factors ), the economic situation in Japan could lead to a sell-off of their US bonds , and have an impact on word economy and eventually on interest rates. On Yahoo finance website : YTD daily total return indicates : 0,97% for CASH,1,08% for PSA,and 0,77% for HSAV ! Does this means that lower NAVs counterbalance the yields after one year ? (but NAV looked relatively stable..).Once I can finally understand those numbers, I wish to choose the most efficient ETF in a non registered account if you could suggest one of the 3 ,considering all factors , as capital gain fiscal advantage of HSAV, VS total Yields and NAVs tendencies. Many thanks for your always very useful clarifications
