Stock price when the opinion was issued
Invests in 0-3-month Canadian t-bills, so returns are guaranteed. The current 4.23% yield and the yield to maturity is 4.98%. The MER is only 11-15-points, so very low. Yields have to rise in the face of inflation, so that helps increase this yield. It holds cash in your portfolio during current volatility.
The more in money market you are, the safer it is because the time to maturity of holding assets is lower. So the shorter the duration, the safer. The more government, the safer, but also a lower yield.
For an enhanced money market yield, he really likes ZST.
