Facebook shares are down more than 10% since late October while the market is up. Arguably, Facebook is down because of slowing growth fears, the incoming administration’s hostility to West Coast tech companies, and renewed concerns (and lawsuits) over unfriendly shareholder voting rights. However, this one-trick-pony (online advertising) may still have a lot of room to run. So do the negatives justify the lower share price, or is now a great time to “buy low” just in time for Christmas!?
