Emerging market funds are over-focused on East Asia – here's how to rebalance your portfolio

What exactly is an emerging market? You can debate all sorts of measures of economic development and levels of income as the cut-off point, but as far as the financial world is concerned, what matters most is whether the stock market is part of the MSCI Emerging Markets (EM) index or not.

The AI boom is starting to stretch this line of reasoning, as we have noted a few times in recent weeks. The performance of a handful of stocks that are integral to the semiconductor sector means the index is increasingly heavy in tech (now 43% of the total). It has almost 50% in two economies – Korea and Taiwan – that are clearly advanced, wealthy countries. Yet while AI has made this very obvious because of its impact on the index, the underlying point has been true for much longer. Korea and Taiwan are “emerging” under MSCI's market-access criteria, but they fully emerged in an economic sense a while ago.

Is China an emerging market?

You can go further. The third largest weight is China, at about 20%. China's GDP per capita in purchasing power parity (PPP) terms is still firmly in emerging market territory – it's about half of the UK's, for example – but this disguises enormous variation between the wealthier coastal provinces and those further inland. It is also by far the world's second-largest economy in nominal terms. To what extent can we view it as a traditional emerging market?

Note, too, that all these three countries – almost 70% of the index – are in East Asia. At this point, is the MSCI EM vastly different to the little-quoted MSCI AC Asia, which adds nearby Japan into the mix? The chart above suggests not.

A “true” emerging market ETF

The practical investor may be happy enough. After all, if returns are good, why split hairs about definitions? Yet it's important to understand where returns are coming from, how an end to the AI boom might change this, and what the options are if you want more traditional emerging market exposure.

I have previously mentioned Barings EMEA Opportunities (LSE: BEMO) and BlackRock Frontiers (LSE: BRFI). Both are interesting, but neither is broad (BEMO is Eastern Europe, Middle East and Africa, while BRFI excludes the eight largest emerging markets).

Instead, we could look at a relatively new exchange traded fund (ETF): WisdomTree True Emerging Markets (LSE: WEMP). This drops China, Korea and Taiwan, with India and Brazil as the largest positions. There is very little tech; you get a classic emerging-markets portfolio with more than 35% in financials.

To my mind, this goes too far for most investors as a standalone holding. It might be preferable to just cap exposure to the big three. Still, owning this alongside a conventional EM fund would be one way to get more balance in a portfolio.
