description: "$XL2CSOPHYNIX(07709.HK)$SK Hynix - WI(SKHYV.US)Hynix's US ADR listing means we don't have to buy this 2x leverage product that's been skimming profits all along. Clear this garbage stock as soon as possible. Hynix's Korean underlying stock closed at 2,201,000 on Friday, down 26.3% from the high of 2,987,000. It needs to rise 36% to return to the high. However, this garbage stock was at 92.98 at 14:00 on Friday (corresponding to the Korean market close), with a high of 193.65. If the underlying stock rises 36%, it will only rise 72%, which would bring it to 92.98*1.72=159.9256. It needs to rise 108.3 points (corresponding to 54.2 points for the underlying stock) to return to the high. During the process of returning to the high, 🐶 the fund manager can skim a total of 108.3-72=36.3 points. All I can say is, clear it out as soon as possible. I've put up with you for a long time."

- **vvvip · 2026-07-11T01:11:24.000Z · 👍 3**: Um... don't all leveraged ETFs experience decay? It's not like only this one has it, right?
- **小熊内裤 · 2026-07-11T00:56:59.000Z**: A 2x increase in the primary uptrend is still much more than the underlying stock.
- **秋焰之心 · 2026-07-11T00:23:07.000Z · 👍 3**: First day trading stocks? The root cause of this loss lies in the change of base! Dropping from $10 to $5 is indeed a 50% decline, but the rise is calculated from a base of $5, requiring a 100% increase. Similarly, for a 2x long position, if the underlying stock falls by 2x, wouldn't it be wiped out
- **香港方总长线价值投资 · 2026-07-11T00:15:44.000Z · 👍 1**: Haha, buying and selling, you seem quite excited, but let me remind you, I'll teach you a math problem. For example:100 up 70=170, can it go up 70 points in one day?If it's a three-day one-sided rally, up 100 up 20+30+20💁 Let's calculate how much that is? No intention to argue, just a reminder.
  - **白宮股神唐納德** (2026-07-11T00:56:36.000Z): You're right, 1.1*1.15*1.1=1.3915, 1.2*1.3*1.2=1.872, it's indeed not a simple doubling effect. If we extend the time horizon, assuming the underlying stock returns to its high in 5 trading days, 1.05
  - **十七很牛** (2026-07-11T11:35:31.000Z): It's not the fund managers who are skimming; it's the people who amplified their gains in a one-sided market that took this money.
- **数字游民 · 2026-07-10T23:41:20.000Z · 👍 1**: The underlying stock rose 36%. Twice that isn't 72% unless it's a single-day gain.
  - **香港方总长线价值投资** (2026-07-11T00:18:33.000Z): Kind of cute
