description: "$XL2CSOPHYNIX(07709.HK)$Micron Tech(MU.US)$Sandisk(SNDK.US)$NASDAQ Composite Index(.IXIC.US) Just saw SK Hynix at 59 in my watchlist, feels surreal. Started trading HK/US stocks in March, bought 4 lots at 30, then got halved to 17 due to the US-Iran thing, was totally stunned. It rose 50% the next day, thought there'd be more fighting, so I sold to break even. Then the memory sector kept rising, tried trading around 90, didn't hold. Went to space, didn't end well. Came back from space and memory was already 150-190, made some from buying low and selling high. Then in just over a week, it's at 59 now, really disorienting. Stock trading really grinds you down.My cost for SK Hynix is around 90+, thought it would definitely break even before, AI's main trend is unstoppable. But now I might leave when it rebounds, it's too emotionally draining. Finally, hope everyone makes money!"

  - **三思又三思** (2026-07-13T10:00:51.000Z): Although I want to leave, I'll go back if the main direction doesn't change.
  - **被包养的理查德** (2026-07-13T10:48:32.000Z): Bro, I'm also stuck with a cost of over 90, planning to get out as soon as I break even🥹
  - **三思又三思** (2026-07-13T10:49:37.000Z): This needs to consider your own position
- **美股才能财富自由 · 2026-07-13T09:31:37.000Z**: Buying the underlying stock is still acceptable, but buying leverage is just gambling. If the underlying stock drops 50%, you're finished.
  - **三思又三思** (2026-07-13T09:35:26.000Z): Actually, everyone is saying that the underlying stock is the best, and I fully agree. However, I don't think buying leverage is just being a gambling addict. Especially for SK Hynix, many people only
  - **美股才能财富自由** (2026-07-13T09:49:13.000Z): Leverage has wear and tear, and SK Hynix is still a cyclical stock.
  - **双双2026** (2026-07-13T09:52:37.000Z): Then US stocks shouldn't have the long call tool, are those who buy long calls all gamblers? Buying stocks is inherently gambling, so who is more noble than whom?
