Earnings are after the bell in Starbucks today and the stock is on an aging trend.
Personally, I don't like aging trends. They are like people, in that they are closer to dying the older they get.
I want the young bucks, and I want the ones that have only touched the trend-line two previous times. In the case of Starbucks (SBUX) it has tested the trend-line 6 times in the past and is sitting right on that rising support level. I'd have to consider myself a seller and not a buyer in this situation and if I were holding this stock, I'd simply dump this stock prior to earnings.
That doesn't mean it won't go higher, but I have to work with the information I have on hand, and I see a greater probability that this stock will react negatively to earnings and break the trend-line simply because of how mature the move higher has become.
Take it or leave it, but that would be my approach with Starbucks and its earnings after the bell today.
Here's the analysis on the SBUX chart:
