From a long term perspective the stock is overvalued.
The stock hasn't realized the potential of ecommerce business & the potential that the platform has in creating an ecosystem for the digital world. Tesla is what Facebook should be but the hype in the streets always churns out the dirt creating an illusion of value. The real value/(money) is always silent, backstage working at doing something more valuable disrupting the world.
This perspective is purely based on the real value that lies in the potential of Facebook, be it there great hostile takeovers (like Instagram, WhatsApp) or creating a global platform for providing business opportunities.
