Consider adding to short positions on AZO around $158.15, AAP around $44.8 and ORLY around $38.11. Add more on spikes up

Auto parts stocks such as ORLY (O’Reilly Automotive), AAP (Advanced Auto Parts), and AZO (Auto Zone) have continued to levitate on the theory that consumers will continue to keep their old cars. This view does not square well with improving consumer sentiment numbers. Further, there is a very high probability that the federal government will start providing consumers vouchers of $3500 or $4500 to trade in their older low mileage cars for new high mileage cars. Passage of such a bill may be the trigger to start a down cycle in these stocks. Consider very lightly scaling in ORLY around $36.50, AAP around $41.50, and AZO around $159.00. Scale in as the stocks move higher or if they break down scale in using technical indicators.
