Why is KORU risky?

I asked the AIs

Here is an objective summary of the current position of the domestic stock market along with the investment risks of KORU (Direxion Daily MSCI South Korea Bull 3X Shares) that you asked about.

• Sobering reasons why it feels like the Korean stock craze has ended

① Selective exit of global capital (Governance and Discount)
Foreigners and large institutional capital, regardless of whether Korean semiconductors are performing well or poorly, are pulling money out of markets with low shareholder return rates and insufficient legal and institutional protections—such as physical spin-offs and controlling shareholder-centric management—and moving it to the US, Japan, or stable bonds/gold.

② "Concentration in very few stocks" rather than an "Index Rise"
It is difficult to expect the entire domestic stock market to rise. Only a tiny fraction of large-cap stocks with tangible earnings or policy momentum—such as semiconductors, shipbuilding, defense, and value-up beneficiaries (financials/holding companies)—are surviving, while the polarization where the remaining small-and-medium caps are marginalized long-term is becoming entrenched.

• Investing in KORU (South Korea 3X Leveraged ETF), why is it extremely dangerous?

To put the conclusion first, KORU is an extremely high-risk product that requires significant caution not only for long-term investment but even for short-term trading.

🔴 Risk Factor 1: 'Negative Compounding (Vol Decay)' of 3X Leverage
Leveraged products track daily percentage changes at 3x.
In a market with severe up-and-down volatility (sideways movement and sharp swings) like the Korean stock market (MSCI Korea Index), holding 3x leverage for a long time will severely erode your principal even if the index returns to its starting point.

🔴 Risk Factor 2: Exchange Rate Risk (Dollar-denominated Product)
KORU is a USD-based product listed on the US stock market.
When the Korean stock market falls, the KRW/USD exchange rate usually surges (depreciation of the Korean Won).
The 3x loss from falling Korean stock prices combined with exchange rate fluctuations makes the actual perceived scale of loss far harsher than that of typical domestic 2x leverage.

🔴 Risk Factor 3: Korea Discount Trapped in a Range
An upward-trending index like the US S&P 500 or Nasdaq provides explosive returns when the timing of leverage is right, but the Korean stock market historically exhibits a long "Boxpi" (range-bound + KOSPI) characteristic.
In a sideways market rather than a trending rise, 3x leverage is a shortcut to having your account melt away.

• Guidance for dealing with the Korean market at this point

Refrain from betting on the overall index (ETF) or leverage (KORU): The scenario where the entire Korean stock market surges due to liquidity toward 3,000 or 3,500 as in the past has a low probability. Index leverage carries far too much loss risk.

Precise approach from a trading perspective: If trading the Korean market, rather than "holding long-term," the only valid strategy is to pick up blue-chip export stocks with dominant positions in the global supply chain (HBM/DRAM, defense, power equipment, etc.) at the bottom during sharp index drops and take profits through short-to-medium-term swings.

Main asset allocation into US/high-quality assets: From a risk management perspective, it is wise to keep the core pillar of your assets in US large caps, bonds, or infrastructure, which structurally trend upward and offer clear shareholder returns, while reducing exposure to the Korean market and approaching it selectively.

Let me speak objectively.

• Has the Korean stock craze ended?

The parabolic (explosive) rally phase is effectively over. It is not completely over, but its nature has changed significantly.

In the first half of 2026, the KOSPI showed the strongest rise globally. It nearly doubled compared to the beginning of the year, reaching 9,114 on a closing basis and intraday 9,385 in mid-June. The core drivers were the AI narrative centered on semiconductors (Samsung Electronics, SK Hynix) and leverage from domestic retail investors.

Since late June, a sharp correction began. Dropping over 25–30% from its peak, circuit breakers were repeatedly triggered, and volatility became extremely high. At the end of July, a strong rebound (+17% daily gain) occurred again, but this is closer to a sharp bounce in a high-volatility phase rather than a "resumption of the craze."

As of now (early August 2026), it remains significantly positive YTD, but relative to its peak, it is clearly in a correction phase. Market concentration (semiconductor weight) is extremely high, and accumulated leverage such as margin buying poses high risk for further volatility.

To summarize:
The "craze that felt like it would rise forever" is over, and we are currently in a high-risk, high-volatility phase. While the potential for further upside remains open, it is difficult to expect the same one-sided rally as before.

• Is investing in products like KORU dangerous?

It is extremely dangerous. It is particularly unsuitable for medium-to-long-term investment.

KORU is a daily 3x leveraged ETF. It is designed to track 3 times the daily return of the MSCI Korea Index.

Major risk factors:

Daily Reset + Compounding Effect: Because it resets daily to match its goal, during volatile periods when the index moves sideways or declines, the principal rapidly melts away. Long-term holdings often yield results far below the actual index gain.

Volatility Drag: If sharp ups and downs repeat like in the recent Korean market, losses can grow exponentially. In fact, during the sharp drop following the peak, KORU recorded a massive drawdown.

Structural Limitations: Leveraged ETFs are products designed for "short-term trading." Direxion itself explicitly states that it does not guarantee target returns for periods exceeding a single day. Leaving it unattended after buying carries a high probability of severe capital loss.

Costs and Tracking Error: Fees (around 1.3%) and additional costs arising from the use of derivatives occur.

In conclusion, KORU:

Is a tool that should only be considered when making a directional bet with strong short-term conviction.

Is unsuitable for average investors buying and holding simply because they feel "Korean stocks might go up."

Should be avoided unless you have the loss tolerance and readiness to monitor it daily.

Overall Opinion
The Korean market remains tied to semiconductor performance and the global AI cycle, so the potential for further upside has not completely vanished. However, the craze phase has passed, and we are now in a period where risk management is far more important.
3x leveraged products like KORU magnify that risk extremely. Being realistic, it is a product that is hard to recommend to most retail investors.
