- **新用户_gEOewT · 2026-07-22T07:34:22.000Z**: If there's anything you don't understand, the underlying stock closed down 0.3%, with a premium of over 1%. It's around -2.* now. None of the 2x stocks strictly maintain a 2x ratio.
- **JW的Targa梦 · 2026-07-22T06:21:46.000Z**: Down by two times, up by one time. Southern [Company] keeps the remaining one for itself.
