Has a U.S. Exceptionalism Theme Left Global Portfolios Exposed to Concentration Risk? (ACPM The Observer)

Stephen Jenkins wrote an article for ACPM's The Observer magazine discussing why investors may want to consider re-balancing away from an over-exposed U.S. stock market.

The Home Country Bias Series

While auto original equipment manufacturers and suppliers have been at the center of discussions, other major industries are also feeling the effects of tariffs. In this installment of The Home Country Bias, we will look into the U.S. agriculture sector – and on multiple fronts.

A Resemblance to the 1966-1982 Sideways Market

1966-1982 was a period of high inflation and weak economic growth: in short, stagflation. More recently, during the four years since rates bottomed and subsequently rose from the lows in the summer of 2020, the market has delivered a stealth value recovery in major markets outside of the U.S. (the U.S. market is distorted by the Magnificent 7 stocks). This seems reminiscent of the early stages of the 1966-1982 period.

It’s challenging to measure the full impact of Trump’s statements on the Canadian stock market with any accuracy. Protectionist policies will likely be front and center for the new U.S. administration, and as their largest trading partner, Canada will be a focus.

Increased Market Risk Warrants Defensive Tilt

Today, the S&P 500 Index and the MSCI World Index are increasingly concentrated on a small group of U.S.-based technology related stocks. Looking back at market history, we believe that risk has increased in portfolios benchmarked to these indices, since expectations on these stocks are high and so too are their valuation multiples, setting up for disappointing future returns.

The Great Divide: Public or Private Equity?

Over the last four years, equity markets have seen a stealth value bull market. However, despite this outperformance, value managers have not yet seen large asset allocations being directed to this turnaround story. One of the possible drivers of the lack of interest, is the fascination with private equity (PE). Warren Buffett at his 2019 AGM commented, “We have seen a number of proposals from PE funds where the returns are really not calculated in a manner that I would regard as honest. If I were running a pension fund, I would be very careful about what was being offered to me.” An audacious quote, even from Warren, and an idea investors might be mindful of as they make asset allocation decisions.
