Put / call positions from the 13F — totals include every disclosed option leg
| Type | Underlying | Notional value | Underlying shares |
|---|---|---|---|
| CALL · bullish | ECHOSTAR CORP-ASATS | $3.0M | 30K |
| PUT · bearish | AVIS BUDGET GROUP INCCAR | $1.2M | 8K |
| CALL · bullish | CAESARS ENTERTAINMENT INCCZR | $302K | 10K |
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.
