WERN - Werner Enterprises, Inc. – The truckload freight services firm edged onto our ‘hot by options volume’ market scanner due to bearish trading in the June contract. Shares of WERN slipped 0.5% lower this afternoon to $20.22. One investor initiated a ratio put spread by purchasing 6,000 put options at the June 20 strike for 2.25 apiece, and by simultaneously selling 12,000 puts at the lower June 17.5 strike for 1.10 each. The net cost of the trade is reduced to just one nickel per contract. The trader is probably aiming to protect the value of a long position in shares of WERN through expiration. Downside protection will kick in if shares decline more than 27 cents from the current price given the effective breakeven point on the trade at $19.95.

MDVN - Medivation, Inc. – Long-term bearish activity in the June 2010 contract suggests one investor may be bulking up on downside protection in case shares of biopharmaceutical company, Medivation, Inc., continue to decline. The stock is currently trading less than 0.5% lower to stand at $26.51.

The net cost of the pessimistic play amounts to 5.93 per contract. The spread was most likely initiated by an investor holding a long position in the underlying shares. Putting on the protective stance shields the investor from losses beneath the breakeven point at $16.57. However, if the trader is in fact long the stock, he will suffer a 38% decline in the value of MDVN before downside protection kicks in at the breakeven price described. An alternate scenario is that the investor does not hold a long position in MDVN. If this is the case, the trader is uber-bearish and expects to garner profits from significant declines in Medivation through expiration in June.

GT - The Goodyear Tire & Rubber Co. – Option traders populated the November contract on GT with bullish plays this afternoon. Shares added more than 2.5% during the session to arrive at the current price of $17.83.
