With the recent deep retrace, this presents a long setup opportunity with favorable risk/reward.
Using the recent 621 low as a stop, 805 would be an initial measured move trade target. Assuming an entry close to today's closing price, this would be close to a 4:1 trade. We think there is potential to ~ 910, which would be closer to 6.5:1. Trade setup is invalidated below 620.79
