Historical option prices for this thinly-traded ticker. Live quotes are wide and stale — use where each contract actually traded plus its 30-day range to place a limit order. 89 contracts (avg 485 vol/day, 88 traded recently)

CAI averages only 485 option contracts/day, so quotes are thin and bid/ask spreads run wide. Use the last actually-traded price below to set a limit order rather than chasing the displayed ask. Most tradeable call: the $20.00 01-15 call last traded $8.60 on 10/07 (now $11.50/$15.00) — try a limit near $11.50. Also watch the $40.00 04-16 call last traded $3.60 on 10/12 (now $3.60/$5.20) — try a limit near $3.60; the $35.00 01-15 call last traded $3.55 on 09/28 (now $3.00/$4.50) — try a limit near $3.55. Most tradeable put: the $35.00 12-18 put last traded $7.00 on 10/05 (now $4.40/$7.40) — try a limit near $5.90.
