Option Block 337: Looking Back on the Flash Crash

Trading Block:  Options traders were preparing for 10% swings of Tesla before week's end based on a straddle. On Wednesday, volume in Twitter options increased fivefold, all but erasing value in a series of bullish contracts. ICE reports record Q1 profit. After its June IPO, Euronext plans to be listed on three of its exchanges. May 6 marks the fourth anniversary and it's a reminder that not much has changed. 

Odd Block: Put sellers in BBEP, call spreads trade in Cameco Corp., calls trade in DLX, closing put seller in FTR.

Strategy Block: Calendars vs. verticals, part deux. 

• Comment from Erik Ruehr re: Mike Tosaw’s survey. I say vertical spreads are better now. Thanks for the show.


• Comment from Tom S.: In response to Uncle Mike’s survey: In general, I’d say vertical spreads trade much better now.


• Comment from LJO: Put me down in the plus column for verticals.

Around the Block: Some earnings left: CSCO, TTWO, CBOE, GRPN. Macro, macro, macro, 10-year, 30-year, the Fed. Will social media/tech stocks hold up?
