After years of U.S. stocks besting international markets (and more of the same so far in 2022), investing internationally seems to have a bad rap among many U.S. investors. We explore and debunk three “myths” to show why we think international stocks should hold a place in most long-term portfolios.

Myth #1: Global diversification doesn't work anymore. 

It’s no secret that U.S. stocks have had the upper hand on international markets for years —since around the start of the prior decade. To date, 2022 has been no different. The combined effect of U.S. stocks’ better performance and the strength of the US dollar drove the disappointing performance of international stocks. After what might feel like a very long period of U.S. market dominance, it’s fair for investors to wonder why they should bother investing both at home and abroad. To illustrate the value of global diversification at work, in Figure 1, we present rolling three-year returns for U.S., non-U.S. (developed and emerging), and global stocks from December 1990 through October 2022.

The dotted line represents global stocks. Whether U.S. or non-U.S. stocks have outperformed over any period, global stocks are always somewhere in the middle —neither the highest nor the lowest. This highlights the benefit of diversification for those that invest across global markets. Investors may avoid some potential downside in exchange for giving up some potential upside.

In my first faculty job at NYU, I taught an Intro Marketing class to a few sections of undergrads. Even though I was about 12 years older than the students, I still felt quite young – I was only 32, after all! Plus, it seemed like my students and I were more or less on the same page … that is, right up until I had one of my first office hours appointments. As I was writing some emails and listening to a Spotify playlist, a student walked in and suddenly exclaimed, “Wow, this is not the same sort of music that my parents listen to!”

“Obviously, it’s not the same music,” I thought, “her parents are probably about 20 years older than me; there’s no way she can think I’m that old.” But of course, that’s exactly what she thought.

Shortly thereafter marked the first time I looked in the mirror and asked myself, “Am I … getting old?”

It was also the first time that I started thinking earnestly, not just about my age but about how my age might affect my choices, especially my financial ones (I’m a business school professor, after all).

It isn’t a financial service and shouldn’t be regulated as one. Laws on gambling are more relevant.

Before FTX crashed, crypto lobbyists and many politicians were complaining loudly that crypto trading was being unfairly denied full participation in banking and finance by overly cautious regulators. We should thank our lucky stars that somebody showed good sense.

Granted, crypto trading looks a lot like the forms of finance we’re all familiar with. It’s made up of things called “exchanges,” “brokers,” “lenders,” “deposits” and “hedge funds.” The financial press breathlessly reports their every move. Crypto also carries the special mystique of the blockchain, which has let traders treat critics as anti-innovation Luddites.

Yet in the most crucial respect, the crypto marketplace isn’t at all like traditional finance. Finance and financial services exist for a purpose that crypto trading lacks. As a Nobel Prize-winning economist Robert Shiller once wrote, “Finance is not about making money per se . . .it exists to support other goals—those of society.”

Cognitive biases can lead investors astray, but here's what you can do to overcome them.

Humans like to think of themselves as rational, and economists have historically modeled the markets with the assumption that people will act rationally. Instead, investors tend to react to market movements with a range of biases, from overconfidence to costly loss-aversion bias.

Behavioral finance, pioneered by Daniel Kahneman and Amos Tversky, challenged the steadfast belief that markets are driven by classical economic theory.

This past year was marked with pronounced emotional moments where investors went from feeling like it was 1929 in March 2020, to feeling like they were experiencing the 1999 market euphoria in January 2021.

One of the most important things you can do as an investor is to understand ingrained psychological biases. Being aware of these biases can help prevent poor decision-making during emotionally charged moments. Here are three biases to be aware of and how to combat them:

• Overconfidence bias
• Loss aversion
• Confirmation bias
