What is behind the drop in Coupang shares?

Coupang shares were listed among the holdings that weighed on performance in Baron Fifth Avenue Growth Fund’s second-quarter 2026 investor letter. According to the fund’s assessment, the stock fell 7.7% after the company issued weaker second-quarter guidance following its first-quarter results.

Although revenue came in line with expectations, pressure on margins stood out as the company continued to absorb the impact of capacity and supply-chain investments made before the 2025 data breach. That strain on profitability was compounded by a 624.7 billion won privacy fine imposed after the data breach investigation.

Another factor deepening weakness in the stock was the shift of short-term capital toward artificial intelligence and semiconductor companies. That rotation added to selling pressure in a stock already under strain from the fine and margin concerns.

What do the market figures show about the scale of the pressure?

At the close on August 31, 2026, Coupang shares were trading at $16.06. The company’s market value stood at $28.87 billion, while the stock had lost 4.29% over the past month and 43.47% over the past year.

  • 52-week trading range: $14.92-$34.08
  • Share of hedge fund portfolios: 97 funds at the end of the second quarter, up from 86 in the previous quarter

According to Baron Capital’s letter, the fund returned 24.6% in the second quarter; even so, Coupang was among the positions that reduced quarterly performance. The picture suggests that the broader market rebound has not fully erased company-specific risks.

What are investors watching now?

Membership recovery and Taiwan operations

Fund management continues to argue that the margin pressure is temporary. It also sees the privacy fine as removing one long-standing source of uncertainty, while the data breach is not viewed as pointing to a structural loss of market share.

One of the key indicators is the recovery in WOW Membership, the company’s paid subscription program. As of the end of April, about 80% of the membership decline seen after the data breach had been recovered, and returning subscribers were said to be approaching their previous spending levels. Investors will now be watching the trajectory of margins, market share gains in the core market and the impact of scaling in Taiwan on financial results.
