Techie Tuesdays: Starbucks

by profsilver on November 4th, 2008

This is the second edition of Techie Tuesdays!Today’s stock is Starbucks.  I chose Starbucks because I have been spending a lot of time blogging from their comfy couches with a Vanilla Frappuccino.

This Tuesday, I would like to introduce the Bollinger Bands.  The bands provide two price lines on a chart, the upper band representing the high and the lower band representing the low. Techniques for using the bands vary from trader to trader, here are a couple of explanations from wikipedia: Some traders buy when price touches the lower Bollinger Band and exit when price touches the moving average in the center of the bands. Other traders buy when the price breaks above the upper Bollinger Band or sell when price falls below the lower Bollinger Band.

Take a look at this link for SBUX chart.

SBUX recently touched the higher band and promptly retreated.  At the current price, SBUX sits above the moving average and about 50 cents shy of the upper band. The distance between the bands is relatively large, indicating substantial volatility.

Looks like the bands offer no clear cut recommendation but, if you had been following the bands using either rule from wiki you should have sold.  If you followed the first rule, you would have sold once it crossed the moving average.  If you followed the second rule, you would have sold a few days ago when the stock touched the upper band.

TST Bollinger Recommendation: SELL

The Bollinger Bands typically use 20-day periods which many argue as too short to tell anything significant.  So for a short-term play, this may be a relevant conclusion.  I do not recommend using any of the technical analysis tools I highlight in isolation. 

And since I like SBUX so much (and prefer to opt for long term investments) I respectfully disagree :)
