The Globe and Mail reports in its Saturday edition that the chatter is loud: Are we in a bubble? The Globe's Tim Shufelt writes that the S&P 500 is tracking toward a 30-per-cent increase on the year, while Canadian stocks are not far behind. The bears point to inflated U.S. stock valuations that invite comparisons to the dot-com bubble. The bulls counter that the stock boom is justified by soaring corporate profits at a time of profound technological change. There is a third camp -- agnostics. They answer the bubble question with a question of their own: Who cares? Not only is it a liberating mindset, it is also the right one for most investors saving for retirement to follow. From the Great Depression to Black Monday to COVID-19, our hapless investor is there to put his nest egg on the line the very day the market peaks, just before disaster strikes. How might things have turned out? Just fine, in all cases. From those precrash peaks to today, the S&P/TSX Composite Index posted average returns of 6 to 7 per cent a year, including dividends. In the case of the pandemic, the Toronto Stock Exchange has seen annualized gains of 11 per cent since the market hit its top in February, 2020. Stick with the program.
