Nvidia's Scary Valuation Is No Reason to Head Overseas

With US valuations ostensibly high compared to global peers, many investors are asking themselves if now is the time to dip their toes into international equities. They’re asking the wrong question. It’s better to focus instead on optimal sector allocation. After all, international stocks are mostly just a means of diluting one’s exposure to technology companies.

In fact, the entire narrative about “relatively expensive” US stocks is a bit misleading. The S&P 500 trades at about 20 times forward earnings, versus about 14 times for all other developed markets. The US index looks expensive principally because it has the largest weightings in tech (Nvidia Corp., Microsoft Corp., etc.) and communication services (Meta Platforms Inc., Alphabet Inc., etc.) by a wide margin. Those categories make up about 38% of the S&P 500, and just about 13% for the rest of the developed world. In America, as in other countries, investors have been willing to pay up for the potential, however uncertain, that strong growth in those sectors will continue.

Overweighting Tech

Investing in Japan’s broad equity indexes, on the other hand, translates to a heavy concentration in the industrial sector; for Europe, it’s financials and consumer discretionary; while Australia has more than half of its index weight in financials and materials.

Looking back at history, it’s understandable that investors have come to think about diversification in geographic terms. US stocks have trounced the rest of the world for about 15 years, and there’s a temptation to believe that secular trends must necessarily die of old age. Past periods of US outperformance (1989-1992; 1995-1999) have been considerably shorter and have tended to be followed by underperformance (1993-1994; 2000; 2002-2008).

Yet the growth of global trade and the emergence of multinational giants have made decisions about “country allocation” less relevant than they were in the past, and fast-moving markets tend to zap away any cross-border relative-value arbitrage opportunities as fast as they can appear.
