Since its highs 2 months ago, the price of Facebook has declined about 36%, which is almost 1/3 of its value.
This is surely not a good sign.
To make things worse, the probability of further decline is pretty high.
After forming a double top (it could also become a H&S instead if it forms a right shoulder), the price has also broken the neckline, which by most measures would put it strongly in bearish territory.
It will very likely have some sort of rebound soon, but I will be hesitant to buy for the long-term until winter is over.
