Q: what are your current favorite Canadian proxies for the S&P500; and the Nasdaq

Q: I have made good profit by investing in these ETF's. Now as the S&P 500 begins to roll down, I see losing some of the gains made so far. Should I sell these ETF's and park the money in cash and wait for the S&P 500 to move up and then invest it back. Alternately , should I leave it invested in these two ETF's. This is part of my fixed income investment. Thanks for the excellent advice you guys have consistently provided.

Q: I'm looking for TFSA investment suggestion.
Possibly and all in one ETV to keep it simple but not necessarily.
Ideally more aggressive as I don't plan on touching it for a long time, possibly to even leave this as inheritance in my estate (I'm 60).
Any guidance you can provide is appreciated.
Thank you
