Long term historical performance is kind of useless in years after a huge move up or down in indexes, or during an economic recovery. I patterned my decisions since March 2020 based on what occurred 2009-2012. Strong commodities ( especially Copper ), strong CDN$, strong cyclicals like Cdn banks, strong TSX off the bottom. Two aspects that didn't repeat closely were IT was much stronger in 2020 then 2009/2010 and Gold/Silver miners ran up super strong and fast but then cratered for 7 months.
If you want to look at historical decisions since 1995, simply putting all your money in TD Bank stock was far better then owning QQQ. Nobody knew that in 1995 though.
