Q: I asked this question on June 1, 2025 but did not get an answer so I am asking again.

What is the difference in underlining risks between ZST and high interest saving ETFs like CASH and HSAV?
What is the difference in yield between them?
I have about $100k in cash to park for 1 year ish so I am looking for a bit of yield during this time.

Q: I’m thinking of switching my cash from CASH and HSAV to ZST. The reason is ZST now has a higher yield than CASH and HSAV (3%+ versus 2.6-2.7%)The intended duration is about 1 year.
What are the risks associated with ZST? Is ZST riskier than CASH and HSAV?

Q: Is TDB8160 as good as these others? What is the advantage or disadvantage to the others, and is one more liquid/safer than the other? Thank you!
