Investment Insight – Summer 2026
One of the recurring challenges in writing our quarterly commentary is that by the time it reaches publication, parts already feel dated. This feels especially pronounced today as the pace of change appears to be accelerating.
After the S&P 500 declined by roughly 10 percent by the end of March, it took just 11 trading sessions to fully recover — among the fastest recoveries on record. As one market observer noted, “for situation monitors, the whiplash is a thing to behold…for everyone else, they may not have even noticed.” More notable was the speed at which the narrative reversed. By late March, many big-tech valuations appeared more fairly valued; by late April, they again appeared stretched.
The increasing frequency of such rapid shifts raises a broader question: Does this reflect a changing market regime?
Part of the explanation may lie in how the investing landscape itself has evolved over recent decades. Information is now disseminated globally in seconds. Combined with trading automation and declining transaction costs, this has contributed to a significant increase in market activity. In the late 1980s, the New York Stock Exchange averaged around 500 million shares traded daily; by 2020, this figure had doubled to over one billion.1
Participation has also become democratized. Building a diversified portfolio once required meaningful capital. Today, internet access and low-cost, diversified products have lowered barriers to entry. In 1990, equity and investment fund units represented just six percent of Canadian household assets. In 2025, they accounted for over 25 percent.2 This has also influenced investor behaviour. The average holding period for a stock, once
spanning years, is now measured in months.
