It wasn’t long ago that China’s market was promoted as a big investment opportunity. The narrative revolved around capturing the country’s astounding growth. A booming economy and rapidly evolving stock market were fertile ground for investment opportunities.

China’s market remains in the spotlight today but for very different reasons. The central party hasn’t been bashful about meddling with some of the country’s publicly traded companies. Such circumstances aren’t new for emerging markets. Government actions have adversely affected stock performance in other emerging markets over the past decade, such as Russia and Brazil.

China’s stock market isn’t riskier than it was several years ago. Its government was always working behind the scenes to guide the country’s economic growth and spur its market higher. China’s central party was largely responsible for expanding its economy through a series of reforms that began in the late 1970s. Ever since, it has been loosening or tightening restrictions as it saw fit, with implications— both good and bad—for investors.

China’s invisible hand

There’s no denying China’s impressive growth over the past two decades. Its gross domestic product grew at slightly more than 13% per year over the two decades through 2020—almost 10 percentage points higher than the rate of US GDP growth over that same span. The Chinese stock market, while not the best-performing emerging market over that period, still ranked near the top.

The foundation for that explosive growth started taking shape in the late 1970s, when China’s central party embarked on a series of reforms to grow its economy and improve the lives of its citizens. It took measured actions over the ensuing decades to become a major player in the global economy, including privatizing some state-owned companies, joining the World Trade Organization, and more recently, expanding foreign investors’ access to China’s locally traded stocks on the Shenzhen and Shanghai exchanges.

Underneath that impressive effort was a rapidly shifting stock market that has come to resemble those of Western countries. Just ten years ago, oil drillers and major banks dominated China’s market. Today, companies operating in the technology, consumer discretionary, and communications sectors rank among its largest publicly traded firms.

Relatively strong performance and access to a growing pool of publicly traded stocks have pushed China’s market into a precarious position among its emerging-markets peers. It accounts for one third of many emerging-markets indexes and the exchange- traded funds that track them.

China’s looming weight in emerging-markets ETFs is a concern, but deteriorating diversification is only one of the risks it presents. While China’s central party has loosened restrictions to grow its economy, it can also tighten them in ways that harm investors. Several emerging markets, including China, are subject to political risk, or potentially adverse interference from their governments.

Ulterior motives

Government interference isn’t a new source of risk in emerging markets. Other recent examples include Russia’s mandated dividend payouts from its state owned companies, or Brazilian politicians that personally profited from bribes at state-owned energy giant Petrobras PBR.

Those cases are directly tied to state-owned companies, where the connection between government actions and company performance is more direct. Politicians who serve in executive roles or on boards of directors at state-owned firms may influence operations in ways that compromise earnings but benefit a country’s economy or its citizens.

China stocks

In a similar fashion, China’s government has not hesitated to meddle with domestic businesses to achieve its political ambitions. Late last year, the central party halted Ant Group’s IPO. A few months later, it mandated that several publicly traded education companies change their status to non-profit organizations. Neither event was good for investors, nor did they build confidence in China’s market. Ant Group wasn’t able to raise capital through the public market, and tutoring companies, such as Gaotu Techedu GOTU and TAL Education Group TAL, saw their prices decline by more than 80% over a few months.

While the potential for interference isn’t new, the scope has changed. Unlike the other examples from Russia and Brazil, the recent actions of China’s central party were aimed at private companies. That sends a big message by demonstrating that the government won’t limit its interference to state-owned enterprises. Some of these actions were also bolder than they had been historically. Ant Group’s stalled IPO was expected to be one of the largest on record.

Context matters

The market appears to have responded to the central party’s actions. Over the 12 months through September 2021, iShares MSCI China ETF MCHI fell 7.5%. Some of that decline was tied to stocks like GOTU and TAL. The rest was likely the market pricing in future actions that may affect other Chinese stocks. Despite China’s large position in the emerging- markets universe, investors were still better off in a broader emerging-markets ETF. IShares Core MSCI Emerging Markets ETF IEMG , which earns a Morningstar Analyst Rating of Bronze, gained almost 20% over the same period.

It also helps to consider China’s position in the global market. Chinese stocks account for just 4% of global market capitalisation and have a long way to go to catch up to the US market’s 59% stake. In the context of a globally diversified portfolio, risks specific to Chinese stocks remain relatively small.

Avoiding emerging markets altogether is a trivial alternative. Foreign developed-markets index funds don’t possess the political risks present in China and other emerging markets. They capture a majority of the available overseas market capitalisation, meaning they’re still a reasonable way to invest abroad. developed-markets index funds in the foreign large- blend category. Cutting emerging markets altogether eliminates any potential upside these markets offer. However, their advantages are already limited by their relatively smaller share of the global market.
