Sorry for the clumsy title. CECO is up 20% today; it's a bit above $35 now. The May 30 calls are up $4.25 to $5.30. What's surprising to me is that the volume on those calls is relatively low. OI is 3913, but volume today is only 344. The volume on the 35 calls (OI 1190) is 1487, 30 puts (OI 8318) is 1575, Jun 35 calls (OI 2412) is 1022. Volume on the stock is 8.5 million. My question is, can anything be read into the fact that options that have moved up in price by 400% are barely trading? Are holders complacent and expect the price to keep going up? (I suppose they could be exercising a bunch this evening).
