3/12 Roads not taken

I've chosen not to analyze seven stocks showing psar bull signals. Here's the list and the reasons why.

My underlying principle is that if the reason for the signal is known, then I'm not interested because it's already reflected in the price.

• AMLN, bear, news: FDA findings
• ABT, bear, analyst
• CLF, bull, analyst
• HPQ, bull, company forecast
• ATPG, bull, company forecast
• CYTX, bear, earnings
• CMC, bear, company forecast

Abbreviations:
psar - Parabolic Stop and Reverse
adx - Average Directional Index
pps - Person's Proprietary Signal
ma20 - 20-day moving average
macd - Moving Average Convergence-Divergence
mfi - Money Flow Index
sto - Fast Stochastic
