Facebook (FB) has had half a Trillion dollars scalped from its value recently, as noted in the following article.
CEO Mark Zuckberg, himself, has been a seller, not a buyer, for several years, as shown here.
FB is approaching its 'Chaos Zone,' which begins around the 200 level, as shown on the following monthly chart.
A drop and hold below that level could send it plunging to 120, or lower in short order.
Or, we may see it whipsaw within that zone for some time before this stock and its social media platform, either recover, or fizzle into obsolescence.
At the moment, the sellers are firmly in control on this timeframe...favouring the fizzle scenario.
