It's possible we see this target met during , so being long is the natural thing to do here.
Fundamental valuation isn't good for FB here, it's expensive, considering yield and free cash flow yield metrics, as well as price to sale ratio to name a few.
If you hold shares you can sell them at higher prices soon, perhaps swap them for a company with better growth prospects like the ones I posted recently.
The scale deformed my chart when publishing...this is how it should look. (strange, probably an error)
