just a glitch... or something serious?

After trading in an uptrend channel for 6 months, McDonalds ($MCD) not only broke down of the aforementioned channel, but also from its 50 daily moving average. All this happened on heavy volume, 2.3 times the average daily volume, also known as ADV. The RSI hinted on a bearish divergence for more than a month now. It will be interesting to see the follow through in the coming days.
