For me it depends what the technicals are saying. If it broke some resistance and technicals suggest a long downturn and earnings are climbing and business managment is operating very well, i would buy. I think Warren Buffett would buy a company that has excellent earnings power, and at a good price, he will not buy something that he thinks is very expensive. he runs calculations (in his head without calculator) and determines a value, if that offers a margin of safety he would buy, if not he wouldnt. I dont follow technicals that much, but do look at the chart briefly before buying though, but without much analysis, just like to compare where the shareprice is compared to the earnings, i make my own chart overlaying earnings and dividends, this makes one see how the relationship between the shareprice and fundamental data is, that drives my decisions much more than anything technical... i only buy companies i really like, trust management 100% and believe there is potential over long term. i hope this helps.
