Last month, one of the highlights for me was watching my son compete at the Canoe Kayak Canadian National Championships at Mooney’s Bay here in Ottawa. For several days, more than 1,400 athletes and hundreds of volunteers took over the bay, creating an incredible atmosphere.

I was, of course, a proud dad. My son had a great week, coming away with two gold and three bronze medals. But what struck me most wasn’t just the results. It was seeing, up close, the enormous amount of work that had gone into getting every athlete to the start line.

Behind each race were countless early mornings, hours of training, setbacks, adjustments and incremental improvements — most of which happened well away from the excitement of competition day. The medals may be decided in a matter of minutes, but the preparation takes months and, in many cases, years.

There is a lesson in that which translates remarkably well to investing.

Markets tend to focus our attention on the “race day” moments — an interest-rate announcement, an election, a trade dispute, geopolitical conflict or a sudden move in the market. But successful investing is rarely determined by any one event. More often, it is the result of the less exciting work done beforehand: having a plan, remaining disciplined, making adjustments when necessary and staying focused on the longer-term objective.

With that in mind, this month I want to step back from the daily headlines and look at a few of the issues that I believe matter most for investors as we head into the fall.

Canada–U.S. Trade: Manageable for Now, but Worth Watching

Trade tensions between Canada and the United States continue to attract headlines. The direct economic impact of the latest tariffs appears manageable, particularly given that they currently affect only a relatively small portion of Canadian exports to the U.S.

The greater concern is what comes next.

A prolonged dispute could weaken the broader Canada–U.S. trading relationship and undermine some of the protections that have supported cross-border trade for decades. Retaliatory measures could broaden the number of industries affected, while uncertainty itself can weigh on business confidence, investment and employment.

For investors, therefore, the important question is not simply the economic impact of today’s tariffs, but whether the dispute escalates from here. A more significant deterioration could put additional pressure on the Canadian dollar and complicate the outlook for Canadian growth and interest rates.

And that brings us to another issue we are watching closely: the bond market.

Government Debt and the Return of the Bond Vigilantes

One of the more important — but perhaps less widely discussed — developments has been the pressure at the long end of global bond markets.

Long-term government yields have moved higher as investors increasingly focus on the size of government deficits, persistent inflation risks and the enormous amount of debt that governments will need to finance in the years ahead. Heavy corporate borrowing, including spending associated with the build-out of AI infrastructure, is adding further competition for capital.

This matters because long-term bond yields influence far more than bond portfolios. They affect mortgage rates, corporate borrowing costs, equity valuations and ultimately the price investors are willing to pay for future earnings.

I have expressed concern about long-duration government bonds for some time. After the difficult experience of 2022, some of those same pressures are beginning to re-emerge. At the same time, gold, silver and other hard assets have remained strong — a reminder that investors are increasingly looking for alternatives to traditional fixed-income assets as a source of portfolio diversification.

This does not mean abandoning bonds. It does, however, reinforce our preference for being selective about our exposure, which may require a few small changes to your portfolios and continuing to look beyond the traditional stock-and-bond portfolio for diversification.

So, Where Does That Leave Markets?

Despite these risks, the underlying economic and corporate backdrop remains reasonably supportive.

Economic growth has remained resilient and corporate earnings continue to be strong. In both Canada and the U.S., consumer spending and private-sector activity have generally held up better than many expected.

That combination has been positive for risk assets, and we remain constructive on equities.

But there is an important distinction between a good economic backdrop and an inexpensive stock market.

Certain areas in the IT sectors have already priced in a considerable amount of good news. Expectations for corporate earnings are high, particularly in the U.S., which means the next stage of the market advance may become more dependent on companies actually delivering those earnings.

In other words, the fundamentals remain supportive — but the margin for disappointment has narrowed.

What Could Go Wrong?

There are several risks we are watching.

Valuations remain elevated in parts of the market. Energy prices continue to be volatile. Questions surrounding the enormous capital being committed to artificial intelligence are unlikely to disappear. And rising long-term bond yields could become an increasingly important headwind if they continue moving higher.

Perhaps most importantly, market expectations themselves have become demanding.

When investors are already expecting strong economic growth, robust corporate profits and a supportive interest-rate environment, it becomes harder for markets to be positively surprised. That doesn’t necessarily mean a major correction is coming, but it does argue for greater selectivity.

It may also create an opportunity for market leadership to broaden. If earnings growth continues to expand beyond a relatively small number of very large companies, areas such as quality companies outside the mega-cap technology names, could become increasingly attractive.

The Bottom Line

Our overall view remains constructive, but measured.

The economic backdrop remains supportive, corporate profitability is strong and we continue to favour equities. At the same time, elevated valuations, government debt, trade uncertainty and pressure on long-term bond yields argue against becoming complacent.

For portfolios, that means continuing to emphasize quality, diversification and discipline rather than chasing whichever part of the market happens to be performing best today.

Which brings me back to Mooney’s Bay.

Watching those athletes compete was a reminder that success rarely comes from reacting to every development along the way. It comes from preparation, consistency and having the discipline to stick with a well-designed plan — while still being willing to make adjustments when conditions change.

I think much the same can be said about investing.
