Apple - one year chartRecently went under the 200SMA which was cause for concern. However, it bounced back over it rather quickly with volume remaining somewhat normal (minus earnings day). That's 3 occasions of approaching support at 180. If it was to dip below it, I would consider a stop loss around 175-177.50. If it can climb over the 187 range with up average volume, I think this thing can run.
