Based on a large options trade in the Financial Select Sector SPDR ETF (XLF), it appears  a well-capitalized trader believes that financial stocks may move sideways for the remainder of the year.  The trader possibly sold a 5,000-lot strangle in January XLF options.  A strangle involves selling a call above and a put below the current price of the stock. The position is profitable if the stock ends up between the call and the put at expiration time.
