The Danger of Betting on One Winner
Hoxton Blog • The Danger of Betting on One Winner
For much of the past decade, investing looked remarkably straightforward. Buy American technology, stay invested, and let the market do the rest.
The biggest US technology companies dominated global markets, and anyone who spread their investments more widely often found themselves questioning whether diversification was really worth it.
So far in 2026, that story has quietly changed. It has not happened with the fanfare of a market crash or a dramatic headline, but the shift has been significant nonetheless. More importantly, it offers one of the clearest reminders of why diversification remains one of the most valuable principles in investing.
The message this week is a simple one. Putting all your money into one country, one sector, or one investment theme might feel like the right decision while it continues to outperform. The problem is that leadership never stays in the same place forever, and nobody knows exactly when it will change. Four charts help explain why.
The US Has Not Been the Best Place to Be
Let's start with how the world's major stock markets have performed so far this year.
Regional Equity Performance in 2026
The biggest surprise is not the performance of the United States. It is the strength of emerging markets, which have returned 22.1%, more than double the US return of 10%. Internationally developed markets have broadly kept pace with America, while Europe has quietly produced a respectable return of 7.1%.
If you invested solely in US shares this year, you have still achieved a positive outcome. But you also missed the strongest-performing region in the world. That is an important reminder that yesterday's winner does not automatically become tomorrow's winner.
This is not an argument for selling American investments. The US remains home to many of the world's highest-quality businesses, and it continues to play an important role in a well-diversified portfolio. The lesson is simply that no country leads forever, and trying to predict which market will outperform next is a difficult game to win consistently.
By owning a diversified global portfolio, you do not need to make that prediction. When leadership changes, as it inevitably does over time, you already have exposure to the regions that begin to outperform. Rather than trying to chase the next winner, you allow your portfolio to benefit wherever growth appears.
How Far Apart the Outcomes Can Be
Looking at countries tells part of the story. Looking across different types of investments tells us even more.
Asset Class Returns in 2026
The first thing that stands out is the sheer gap between the best and worst performers. US small companies have delivered a return of 23.2%, while Bitcoin has fallen 31.5%. That represents a difference of more than 50 percentage points in the same year, highlighting just how dramatically investment outcomes can differ depending on where you concentrate your money.
If your portfolio happened to be heavily invested in the wrong part of the market, your experience this year would look very different from the headlines celebrating record highs elsewhere. At the same time, the quieter parts of the investment world have been doing exactly what they are supposed to do. Bonds, cash and inflation-linked investments have delivered more modest returns, but they have also provided valuable stability while more volatile assets have experienced much larger swings.
This is exactly why diversification exists. It is not designed to ensure you own the very best-performing investment every year. Instead, it is designed to reduce the chances of owning the very worst one. Over the long-term, that consistency is often far more valuable than chasing whichever asset class happens to be attracting the most attention.
Diversification means accepting that you are unlikely to top the performance tables every single year. It also means you are far less likely to find yourself at the bottom of them. For most investors, that is a trade-off well worth making.
"Concentration can make you rich, but diversification keeps you rich. Only one of those is a plan."
Why the Tide Has Been Turning
So why has leadership changed this year? A large part of the answer comes down to valuations. After years of exceptional performance, US shares had become significantly more expensive than many other markets, while parts of Europe, the UK and emerging markets continued to trade at much lower valuations.
Source: Hoxton Wealth analysis based on published data from Goldman Sachs, STOXX and Siblis Research (forward P/E, mid-2026). For illustration only.
This chart shows how much investors are paying for each pound of expected company earnings across the major regions. US shares currently trade at around 22 times expected earnings, compared with roughly 16 times in Europe and around 13 times in the UK. That is a meaningful difference.
Paying a higher price for the same level of company profits can often leave less room for future gains. By contrast, markets that have been overlooked or undervalued may have greater potential to recover as investor sentiment improves. That is one of the reasons cheaper markets have enjoyed a stronger year so far.
None of this means US shares are suddenly poor investments, or that investors should rush to sell them in favour of Europe or emerging markets. That would simply be making the same mistake in reverse by chasing whichever market happens to have performed best most recently.
Instead, it reinforces the value of balance. A well-diversified portfolio includes exposure to the world's largest companies, but it also includes regions that may be temporarily out of favour. When market leadership changes, as it inevitably does, your portfolio is already positioned to benefit rather than having to react after the event.
What Diversification Actually Looks Like
It is easy to talk about diversification in theory, but what does it actually look like in practice? This final chart shows how a diversified portfolio builds its return, with each asset class making its own contribution to the overall result.
Hypothetical Returns of a Diversified Portfolio in 2026
No single investment does all the heavy lifting. US large companies contribute 2.97%, while US small companies add 2.32%. International developed markets and emerging markets contribute a further 2.46% between them, and even the quieter areas of the portfolio, including bonds, property, and commodities, all play their part.
When those contributions are combined, the portfolio delivers a total return of 9.35%. No single holding determines the outcome, and no single disappointment has the power to derail the entire portfolio. Each investment contributes something different, creating a more balanced and resilient result.
Compare that with the previous chart, where concentrating on just one investment could have produced either a gain of more than 23% or a loss of more than 31%. That is the difference between relying on a single prediction and building a portfolio that can perform across a range of different market conditions.
Diversification does not promise the highest return every year, and it is not designed to. Its purpose is to capture opportunities wherever they emerge while reducing the impact of any one investment falling out of favour. Over time, that steadier approach can make a remarkable difference to both returns and peace of mind.
Our Message This Week
It is always tempting to invest in yesterday's winner. After years of US technology leading global markets, it is understandable why many investors have come to believe that this is where all their money should remain.
This year provides a useful reminder that markets do not stand still. So far in 2026, the strongest returns have come from emerging markets and smaller companies rather than the household technology names that dominated the previous decade. Next year, the leadership could change again, just as it has many times before.
The reality is that nobody can consistently predict which country, sector, or asset class will outperform next. Successful investing has never been about getting every prediction right. It is about building a portfolio that does not rely on making perfect predictions in the first place.
That means owning a sensible mix of investments across different regions and different asset classes. When one part of the portfolio performs well, it helps offset the areas that are having a more challenging period. When leadership changes, as it inevitably will, you are already invested rather than trying to catch up.
Diversification is sometimes dismissed as boring because it rarely produces the single best-performing portfolio in any given year. In reality, it is one of the most powerful tools available to long-term investors. It replaces the uncertainty of trying to find the next big winner with the confidence that your portfolio is prepared for a wide range of possible outcomes.
Over a lifetime of investing, that is often the difference between a journey defined by sharp highs and painful lows and one built on steady progress towards your financial goals.
If this week's market moves have prompted you to think about whether your own portfolio is positioned for the years ahead rather than the headlines of today, we're here to help.
