Vingroup Shares See 1,000% Surge Amid Vietnam's Market Expansion

Vietnam's Vingroup JSC Surges 1,000% in 2025, Raising Valuation Concerns

Unexplained gains in Vietnam's biggest stock have confounded seasoned analysts and set off a frenzy among retail traders, raising doubts about how long the rally can last. Vingroup JSC, a conglomerate backed by billionaire Pham Nhat Vuong, has seen its stock price surge 1,000% from the start of 2025 to its peak just two weeks ago, making it the biggest company within frontier markets and one of the most expensive across Asia.

The company's blistering rally has pushed its valuation to new heights, surpassing regional heavyweights Singapore Telecommunications Ltd. and JD.com Inc., as well as any Indonesian company. Vingroup now accounts for about one-third of the benchmark VN Index and trades at 70 times forward earnings, compared to 12 times for the broader market. This significant premium has raised concerns among global money managers, who question whether earnings growth can keep pace with valuations that now stand in sharp contrast to peers.

Analysts point to a mix of aggressive retail buying, improving prospects at key subsidiaries, and optimism ahead of an imminent market upgrade by FTSE Russell as drivers of the rally. However, they remain wary, citing concerns that Vingroup's rapid ascent and outsized weighting in the market risks distorting Southeast Asia's best-performing market over the past year.

Passive investors will also have to grapple with an inflated benchmark constituent when Vietnam is upgraded to emerging-market status in September. The key question now is whether the company's fundamentals can justify its current scale. For earnings to keep pace, Vingroup is relying heavily on Vinhomes JSC, which posted net income of 25.6 trillion dong ($1.1 billion) in the first quarter, roughly ten times higher than a year earlier.

The company's growth has been fueled by a combination of factors, including its diversified business portfolio, which spans electric vehicles, transport, real estate, hospitality, and tourism. However, its reliance on Vinhomes JSC and VinFast Auto Ltd., which has posted significant losses, raises concerns about the sustainability of its growth.

Market positioning also suggests that caution is visible, with foreigners offloading $2.7 billion of local equities so far this year, nearing the $3.3 billion outflow from Indonesia, where markets are grappling with uncertainty over a potential MSCI Inc. market downgrade. Leverage may also have played a role, with margin loans hitting a record 407 trillion dong in the first quarter, according to Fiingroup.

Despite these concerns, some market watchers remain optimistic about the stock's prospects. Nguyen Anh Duc, head of institutional brokerage at SBB Securities, believes that technical flows and long-duration growth expectations may continue to support the stock price in the near-to-medium term. However, others caution that any shift in sentiment could quickly reverse the momentum that propelled Vingroup to dizzying new heights.

The rally's durability may ultimately hinge on whether fundamentals can catch up with inflows, analysts say. With valuations stretched, any shift in sentiment could have significant implications for the stock price.
