The Week
KORU.US tracked a brutal week for South Korean equities. Although weekly change and closing price for the ETF itself are not available from the provided data, the intraday picture shows wide swings: pre-market opened at $11.69 versus a prior close of $12.01, and the after-hours quote printed $10.51 late on Friday, with the latest price at $10.64. The pattern was a sharp gap-down, choppy selling, then a weak technical rebound. The S&P 500 slipped 1.95% this week, while the underlying Korean market fell far more, though a direct weekly comparison with the benchmark cannot be computed for this ETF.
ISHRS MSCI S Korea Capped This Week
The underlying ISHRS MSCI S Korea Capped (EWY.US) opened the week at $172.93, hit a high of $172.93 and a low of $149.71, and closed at $150.44, down 15.12% for the week with a 13.43% range. Day by day: Monday opened at $172.930 and closed at $170.110; Tuesday closed at $166.560 after a rebound from a lower open; Wednesday fell to $159.830; Thursday plunged to an intraday low of $149.710 before bouncing to close at $156.220; Friday faded again to close at $150.440. The series describes a grinding single-direction move lower, with the close well below the 20-day average of $179.341 and the 60-day average of $175.846.
Leverage & Decay
KORU.US is a 3x leveraged ETF, designed to replicate roughly three times the daily move of ISHRS MSCI S Korea Capped, not three times the weekly return. With the underlying down 15.12% on the week, a 3x product would not simply lose 45.36%, because daily rebalancing creates path dependence. If the underlying moved in one direction every day, the compounded result would approach three times the weekly loss, but this week alternated between sharp drops and intraday rebounds, especially on Tuesday and Thursday. That two-way chop erodes compounding returns and widens the gap versus a clean 3x multiple. Holding for longer periods does not equal three times the long-term return, and the drag rises when volatility spikes.
ISHRS MSCI S Korea Capped News
The underlying index endured one of the most violent stretches in recent Korean market history, with headlines clustering between 13 and 15 October. On Monday the KOSPI fell 3% to 6,427.08; Tuesday the drop widened to 5.1% and the exchange triggered a Sidecar halt; Thursday became the extreme session, with the index down more than 9% intraday and the Korea Exchange activating a circuit breaker that paused trading for 20 minutes, while financial regulators held an emergency meeting and pledged stability. Friday brought a rebound, with the KOSPI up 1.8% to 5,653.99 and as much as 3.0% earlier in the session. Across the week, AI-related selling dominated the narrative: JPMorgan warned that retail dip-buying was thin and buyback funds were fading, while Dan Ives argued Samsung and SK Hynix remain undervalued.
The Week Ahead
The macro calendar next week is light and US-focused: 19 October (Monday) brings the NAHB housing market index, with prior and forecast both at 32; 20 October (Tuesday) brings housing starts annualised at 1.305 forecast versus 1.275 prior, and building permits at 1.395 forecast versus 1.403 prior; 21 October (Wednesday) brings EIA weekly crude oil and Cushing inventory data. For KORU.US, the more important watch item is whether ISHRS MSCI S Korea Capped can stabilise after the crash, along with any follow-through from Korea’s promised emergency measures and the repair effort in AI-related heavyweights.
In Short
South Korea logged its worst week since the Lehman Brothers collapse of 2008, with EWY.US down 15.12% and multiple Sidecar and circuit-breaker halts during the week. AI-linked selling remains a key overhang: JPMorgan questioned the rebound setup, while Dan Ives defended valuations in Samsung and SK Hynix, and Korean authorities stressed that fundamentals stay sound and emergency tools are ready. The tension is between unresolved selling pressure and official stabilisation signals, compounded by the decay that a 3x leveraged product suffers in choppy markets. The next test is whether the Korean market can hold near its 200-day moving average and whether AI-related selling pressure finally thins out.
