Analysis

4d ago

This market shows extreme illiquidity with only $2,634.86 open interest and zero 24-hour volume, making the 39¢ price potentially unreliable for serious positioning. The 105.3% implied yield on the Yes side combined with 218% realized volatility and a 2.12 vol ratio suggests significant uncertainty and possible mispricing, though the thin liquidity limits confidence in that assessment. The price has declined 13% over seven days (44¢ to 38¢) with 566 days to expiry, indicating either deteriorating odds for Shortsleeve or natural decay in a low-information environment where info arrives at only 0.6 events per hour.
