Which Markets Will Move? US Policies Matter

What happened last week?

The S&P 500, Dow and Nasdaq gained 0.62%, 0.59% and 0.95%, on post-Fed rate cut momentum. The S&P 500 and Dow each made new all-time highs while the Nasdaq ended the week 2.83% below its July 10 high.

We’ve noted many times that today’s US presidential candidates of both parties have presided over historically large share price increases.

The annualized return for the S&P 500 over the course of the Trump/Pence administration was 16.4% while Biden/Harris has averaged 13.1% to date.

This can be credited significantly to the 10.9% annualized rise in S&P 500 earnings per share over the last eight years, not the person sitting in the White House.

Yet US Presidents do wield much power, and can change market expectations, particularly over the short term. The foreign policy and mix of domestic polices of Harris or Trump are more than enough to sway the expectations of global markets.

3 Things to Know

November Is too Close to Call

Polling data for the US election shows a tight race. The unusual qualities of the US electoral college make it fraught for investors to take a strong view of the outcome.

The close election makes it likely that the results on November 5 will cause certain asset prices to move significantly.

One of the clearest observations of the campaign period thus far is that non-US share prices can swing sharply with the prospects for Harris or Trump.

The discrete events that changed polling data and prediction market odds in favor of Harris or Trump drove significant equity market gains or losses in large regions of the world.

Why would this be the case? As we noted, share prices rose through the economic expansions of both administrations, though interrupted briefly by the pandemic shock late in the Trump administration.

Yet Trump’s tariff increases — mostly focused on China at the time — caused great volatility spikes, more so outside the US.

While it is true that US importers pay the customs duties (taxes) on imported goods, equity and foreign exchange markets can reduce the value of a foreign producer’s business. Tariffs change the economics of international trade.

The past 15 years have been one of unusually strong US outperformance on a sustained basis. US equity market capitalization has risen to a record 65% of the world measured in a historically strong US currency.

During the past century, it was rare for outperformance to persist more than a decade. With this outcome, investor portfolios throughout the world have become “US biased.”

US investors who favored their home market outperformed those who diversified across the world. But is this a risk for their portfolios going forward? At ever-higher levels, one would think so.

Trump or Harris? The Presidency Matters for Markets

To be clear, the US equity outperformance hasn’t been driven on some irrational bias and profits of US firms have outgrown non-US.

And as we showed last year, one can easily find examples of markets strongly rewarding any firm globally that outgrows peers.

A Danish drug maker was one of last year’s strongest equity market performers among global large caps, for example. Yet that was not true for Europe as a whole, as the region’s EPS gains lagged.

Critically, faster EPS growth rates for US firms are strongly embedded in expectations for the future. Therefore, outperformance from here requires raising that expectation further. The valuation of US shares is at a historically high premium to non-US shares.

So, will the US only outperform other regions? It’s possible that the US could gain further. Like 2018, a trade war shock might sink all markets, but the US less for a time.

As we have discussed, the strong growth performance for US technology shares in the decade to date is mostly behind US/Non-US valuation differences. China’s polices are largely behind its weakening corporate performance (see our September 14th CIO Bulletin). These combined boosts to US relative performance might fade.

While we believe it is unlikely, Harris has proposed a somewhat higher US corporate tax rate and other forms of higher capital taxation. A stronger regulatory hand could also restrain US equities at the margin.

We say this while overweight US equities, albeit expressed through segments with lower valuations than large cap US tech. There are no guarantees that the US election outcome and presidential policies will be the decisive factor that changes the relative return picture for US and non-US assets.

But at a record high for the US share of global markets, it is critical to keep an eye on what might change a powerful driver of portfolio performance.
