[Analysis: SK Hynix ADR Premium Over Korean Shares Once Reached 51%, Reflecting Overheated AI Chip Trading] BlockBeats News, July 26, according to The Wall Street Journal, SK Hynix's ADRs listed in the U.S. this month have consistently shown a high premium compared to its Korean-listed shares. Each ADR represents 0.1 shares of the Seoul-listed stock and can be easily converted into Korean shares. However, over the past two weeks, the premium relative to Korean shares has fluctuated between 16% and 51%, reaching 29% as of Friday. U.S. investors have been willing to pay a higher premium to trade SK Hynix shares directly in New York rather than seeking brokers capable of trading Korean stocks. This reflects not only the U.S. market's willingness to pay higher prices for chip stocks overall but also a particular enthusiasm for memory stocks, further highlighting the current AI trading frenzy. Typically, when there is a significant price discrepancy between dual-listed stocks, arbitrageurs buy shares in the lower-priced market, convert them, and sell them in the higher-priced market. However, while SK Hynix ADRs can be converted into Korean shares, regulatory restrictions make it difficult to convert Korean shares back into ADRs, and such operations cannot be conducted without the company's approval. As a result, hedge funds are unable to engage in risk-free arbitrage, and if the premium continues to widen, shorting ADRs could lead to significant losses. Some of the premium is justifiable, including factors such as Korea's stock transaction tax, lower trading and custody costs in the U.S., reduced currency management needs for U.S. investors due to dollar-denominated pricing, and the greater tax efficiency of ADRs in U.S. ETFs. However, these factors typically account for only a few percentage points of the premium. By comparison, TSMC's ADRs had an average premium of 3.2% from 2010 to 2020, which has risen to an average of 15% since the launch of ChatGPT in 2022. The high premium of SK Hynix ADRs indicates that the U.S. market's demand for AI chips and memory stocks is significantly higher than that of the Korean market. In the future, if investors shift to the lower-priced Korean shares, the company issues more ADRs, or market enthusiasm wanes, the premium may narrow. If the narrowing occurs through an increase in Korean stock prices, ADR investors will be minimally affected. However, if it results from a decline in U.S. ADR prices or a simultaneous drop in chip stocks in both markets, holders may face losses. [Original Article Link]
