description: "$XL2CSOPHYNIX(07709.HK) I saw some bros discussing the decay of this stock. We all know that leveraged ETFs have decay. Due to the recent huge volatility, its actual decay over the past seven trading days is roughly between 0.07% and 0.1% per day.$Direxion Daily Korea Bull 3x Shares ETF(KORU.US) Compared to the 2x Samsung ETF, the decay of this 3x ETF isn't just a superficial doubling, but an increase of about 3 times, which means an average daily decay of 0.25% to 0.3%."

- **重案组曹达华 · 2026-07-10T14:26:54.000Z**: If it surges sharply tonight, there's negative news on Sunday, and then short-sell double the long position in SK Hynix on Monday, only to see SK Hynix skyrocket again in US stocks on Monday night... that's terrifying.

- **素时听风 · 2026-07-10T14:19:04.000Z · 👍 1**: It's said that the decay of a 2x ETF is not as severe as the decay of options plus time erosion, but subjectively, options still feel more comfortable.

  - **巴菲Te北京分特** (2026-07-10T14:20:40.000Z): Hardware and software are like a seesaw; when hardware is strong, software becomes weak😂
  - **JimmyTang** (2026-07-10T14:27:40.000Z): Yeah, I mainly want to clear out my Microsoft January options. Microsoft feels very sluggish; if it doesn't rise, I'm done for.

  - **リムル** (2026-07-10T12:08:46.000Z): Even if SK Hynix returns to 3 million now, this price can't get back to 180, right?

  - **财富星软柿子** (2026-07-10T14:44:03.000Z): That's right, even without a single-sided wear-and-tear market, it's just back to 144, we must add to the position...

- **重案组曹达华 · 2026-07-10T09:48:46.000Z**: Okay, thanks for the info. One question: now that SK Hynix is listed in the US, will that cause everyone to buy the US-listed SK Hynix stock, with few buying the Hong Kong-listed South China 2x Long SK Hynix ETF, leading to reduced liquidity? No one to take over the position.
  - **巴菲Te北京分特** (2026-07-10T10:01:43.000Z): Don't ignore human nature😂, Micron has also had 2x all along.
