Google's culture is fundamentally broken. I don't think it's possible for them to fix this. I'll probably take a short position on Google in the medium future.
Also, it can be really expensive to hold on to a short position for a long time so it might not be a good idea even if there were more substantial reasons to take one.
To me the real question is: what will come of these antitrust investigations into their targeted ad business?
That's the cash cow upon which their stock price is ultimately based. They've been able to get away with a lot of failures because ultimately advertising is such a huge business for them.
But if there's any move to break apart that business or regulate it in a way to create more competition in the market, to me that could be the thing that could start to undermine their share price.
