I'm always on the lookout for unusual option trades. At the start of this year I was the first to spot highly unusual PUT action for $LNCO, for example. It also ended up being a $20-plus million profit for the buyer of those PUTs, for what it's worth. Check ou the $LNCO PUT post here: http://www.optionmillionaires.com/2013/lnco-line-enormous-and-unusual-option-bet-highlighted-months-ago-hits-paydirt/
And how about $LEAP wireless calls? $13k was turned into over $1 million! http://www.optionmillionaires.com/2013/leap-suspicious-13k-trade-could-net-over-1-million-when-the-market-opens-on-monday/
While I try to post the most unusual trades on the blog here at optionmillionaires.com, our forum is where you'll find most of the unusual option trades, volume, activity, etc. I don't post every single unusual trade, or volume, but just the ones I think are meaningful. Take $SXC, for example. On September 11th, 2013 I pointed out some unusual call buying in $SXC (Suncoke Energy). The stock has been on a tear ever since and has posted 17 consecutive positive closes. That's like a 30-game hitting streak in MLB or a 15 game winning streak in the NBA.
Additionally, the calls are up over 500% since then. Simply put, the unusual call buying was a great indicator of where the stock was headed going forward. Here's the link to my $SXC post in the forum: http://www.optionmillionaires.com/forum/showthread.php/564-Sxc Helpfully, you can also find my unusual trades, volume, and posts in the forum at optionmillionaires.com as well: http://www.optionmillionaires.com/forum/
