Since the weekend leaves time for research, I am will try to post multiple trading ideas based on order flow, vol or other unusual things I find. Today I found three that may be worth investigating. Symbol: RVSN Summary: $175 million technology firm. Company: Averages 319 options traded a day. Trade: 10,000 Jan 5 puts sold @ 0.10 on zero OI (all opening). Symbol: CVA Summary: $2.7 billion energy (energy from waste) company. Company: Averages 924 options traded a day. Trade: 5,000 Jun 15 and 17.5 puts. Marked as a spread - but looks to me like it's possibily a stupid (same sided - in this case, both purchases). Symbol: NANO Summary: $128 million technology company. Company: Averages 224 options traded a day. Trade: 2,000+ Jan 12.5 calls trade on low OI. The trades may actually be two sided.
