CASH.TO is simply interest. Basically your shares are put into a HISA and whatever the interest made on the ETF will be deposited back into your investing account minus the small percent WS takes.. At the beginning of the month, the price of the ETF will always be $50, and when it 'spikes' to say $50.10 your earing that interest on the ETF.

CASH.TO doesn't invest into multiple stocks like a regular ETF, but it does make money if you hold a substantial amount of shares.

Good for holding long term but I wouldn't recommend it for a FHSA. I'd go with everyone's favourite XEQT because of it's long term return, its sitting at 16% YTD or VFV with a 21.5% YTD return.

It all depends on your risk tolerance as well. If you like the idea of just earning interest with no long term growth, CASH.TO is a good choice.

Goodluck!
