Today, Value Line upgraded ACO's Timliness rating from 2 to 1. The rankings are now 1 for timeliness: 3 for safety: 1 for technical. While this is about as high as I have seen this stock, V L 1 ranked stocks can stay that way for some time. It also made today's IBD list of "20 stocks on the move" with over a 300% increase in daily volume. It ranked 4th on that list today.
VL also said ACO wasn't a good buy for the long term, although I don't agree. I never liked stop loss, but OLd Guy brings up another great reason not to use them: getting messed up on the open for the stock.
