Put / call positions from the 13F — totals include every disclosed option leg
| Type | Underlying | Notional value | Underlying shares |
|---|---|---|---|
| PUT · bearish | INVESCO QQQ TRUST SERIES 1QQQ | $808.1M | 1.4M |
| CALL · bullish | ROBLOX CORP -CLASS ARBLX | $56.6M | 1.0M |

13F filers disclose option positions at the market value of the underlying the contracts reference, not the premium paid. A put is a bearish bet (it gains if the stock falls); a call is bullish. “Underlying shares” is the share count the contracts control, not a share holding. These legs are excluded from the equity book, weighting, concentration and sector figures above.
