$CAT Short on deck

$CAT is coming into the short area of 86 bucks which is just below the 20 day moving average. I'm going to put a 1/2 position upon a pierce of the 20 day moving average at 86.16. Should it move higher to 87 I will add the second half.

Stop out wil be a close above the 50 day moving average. Downside target on this play is 83. There
