Stock price when the opinion was issued
Regulators have been threatening for several months to clamp down on the returns on these HISA ETFs. Some providers have tossed treasury bills into the mix. Any declines will be limited to only 20-30 basis points. So, he's holding onto his cash ETFs for now. No point in owning several of these, because they're all the same.
Important to note that it's not exactly the same as a high-interest savings account. No CDIC insurance, have to pay trading fees. Very stable price handle until there's a monthly distribution, based on Canadian overnight bank rates. Those distributions have come down as rates have started to decline.
At one point, superior to bonds. But now with yields coming down, money market funds such as ZMMK are very competitive. T-bill ETFs are also competitive.
Good place to park your money, and fees are low.
Not much different from a money market fund, except the quality of the underlying securities might be a bit higher in a MM fund.
