Presenting the chart of AAPL: the stock, which has surged from $240 to $292 in less than a month, has done so without violating the 2 Std Dev upward channel once! In other words, nobody but programs which are designed to trade within the traditional technical upward channel of +/- 2 Std Devs are doing the trading in AAPL. And now that your confidence in a rational, non-binary market has returned, please buy, buy, buy. And pray none of these machines has a short circuit, and/or nobody decides to use the Stuxnet virus on the NYSE.
As for those carbon based lifeforms who are looking at this chart and are concerned by the increasing parabolic blowoff, which soon mean the stock will have to travel backward in time to rise as fast, one may say they have a good reason to be quite terrified.
