Agree it takes time to digest 2017 run-up. But the correct advice is not to be patient, but to cut and run while you are ahead (or have anything left) - we know what happened to paper millionaires in the dotcom bubble on "concept" stocks like pets.com, even better known names with credible business like qcom that rose like crazy in 1999. This store of bubble is worse than a dotcom.
Swing traders should be very happy now. Let's say they shorted on 15 nov at 5600. Now price is 3950, ie 30% profit in 1 week.
