South Korea’s iShares MSCI South Korea ETF (EWY) has advanced sharply on sustained AI-related demand for memory chips, with Samsung Electronics and SK Hynix driving the bulk of KOSPI gains that reached multiple all-time highs above 8,000 earlier in May before a 6.1% pullback on May 15. Year-to-date returns exceed 96% amid record inflows, elevated call-option open interest, and upward earnings revisions tied to hyperscaler capital spending, though May seasonality has historically produced flat-to-negative performance with only a 47% win rate. Recent record outflows of $409 million from EWY on May 7 and accelerating inflation data prompting Bank of Korea hawkish signals introduce near-term pressure on the won and equity valuations. Traders monitoring the week of May 18 will focus on export figures, business sentiment releases, and any shifts in U.S. dollar strength or global risk appetite that could determine whether EWY sustains momentum near recent highs around 193–194 or experiences consolidation.

Only prices achieved during the regular trading hours of the primary exchange on which the listed security trades (typically 9:30 AM – 4:00 PM ET) will be considered. Prices occurring during pre-market or after-hours trading will not qualify.
Prices will be used exactly as published by Pyth, without rounding.
In the event of a stock split, reverse stock split, or similar corporate action affecting the listed company during the listed time frame, this market will resolve based on split-adjusted prices as displayed on Pyth.
The target price will be adjusted proportionally to reflect any stock splits. Resolution will be based on the historical price data as shown on Pyth after any adjustments have been applied.
The resolution source for this market is Pyth — specifically, the South Korea ETF (EWY) "High" prices available at https://pythdata.app/explore/Equity.US.EWY%2FUSD, with the chart settings configured for 1-minute candles.
Historical 1-minute candles may be accessed by appending a Unix timestamp (seconds) to the Pyth chart URL using the "t=" parameter. Any timestamp within the listed market time frame may be used to view the relevant candle data (e.g., https://pythdata.app/explore/Equity.US.EWY%2FUSD?t=1773432000)
If the relevant Pyth data is unavailable due to a system outage, data failure, or other technical disruption that prevents verification of the required 1-minute candle data, the official daily high price published by the primary exchange on which the listed security trades will be used to determine whether the listed price was reached during the applicable trading session.
