Starbucks has been going up since 2009 and is currently undergoing a correction. Earnings aren't until April 24th so there is a lot of time.
The dashed line is holding as resistance and once this is defeated expect the uptrend to continue.
Right now I would short as close to this line as possible and see where it takes us.
Just a note - but mark your idea a "SHORT" instead of a "LONG" to avoid any confusion. Also, SBUX just reported earnings that were pretty disappointing from my perspective especially when considering low coffee and sugar prices. Just my perspective. I agree with your short strategy around that $76-77 level. Nice idea. Good luck. Tim
