Nah, just savvy traders taking profits ahead of the expected dip. They'll buy back in on the dip and either keep some profits or reload with a larger position. Either way, they won't be left behind. This peaked trading at about 100x revenues. Common play.... sell the spike, buy the dip. Personally I sell my highest price shares into a spike and keep my cheap ones as a core holding. I can churn profits and increase my position on the dips....did it a couple of times in 2016.
