THOUGHT
Please always keep your eye on the market as a whole. It is tough for any stock to go green in a falling market (except those with an inverse relationship).
Use all indicators that you can find! I mentioned this one (percent of S&P 500 stocks above their 50 day moving average) as it has been reliable for me, when the % is very high (over 90%), and combined with the market moving as much because of the dollar movement (which is extremely volatile right now) as because of fundamentals of the economy, it certainly looked like a downturn IMO.
How much and how long?????
