Brendan Byrnes: Hey, Fools, I'm Brendan Byrnes, and I'm joined today by our tech and telecom analyst for Fool.com, Andrew Tonner.

Andrew, we recently saw Eric Schmidt selling a bunch of his Google (GOOGL 10.22%) stake; I think a third or up to 40%. What does this mean? Do you think this is any kind of sign that investors can take when looking at Google, or do you think it's more of a diversification play? Insiders can sell for a number of reasons.

Andrew Tonner: Right, exactly. That was actually the big discussion around all of this. Is this a sign that Eric Schmidt now is moving away from Google? Has he given up faith in the company, or is it just a diversifying his assets sort of play?

From what we can tell, the base of the storyline is here: He's trying to diversify his assets. He has $6.7 billion of his $7.5 billion net worth tied up in Google shares right now. As he transitions away from a more active day-to-day role at the company -- he plays that statesman role now, almost -- I think it makes perfect sense.

It's not necessarily a sign that he is giving up on the company, again, because he's retaining a massive absolute dollar stake, even though his percentage ownership will be substantially diminished.

You saw the market react negatively to this, and maybe short-term selling pressure could force the stock down, but the real storyline for someone looking at Google shouldn't be Eric Schmidt selling his stake. It should be that Google is a company that's performing extremely well right now. They knocked it out of the park with their most recent quarterly earnings and -- the one thing that all investors are looking for -- we saw stabilization of cost per click, quarter over quarter.

That's been the big red flag that people have been anchoring on, because we've seen an absolute explosion of searches on mobile devices. Android is just absolutely dominating the overall market share there, but again with those ads not being as profitable, it's been a real red flag and an overhang for Google investors.

We saw that stabilize. Now, we'll want to see stability for a few quarters, or even improvement, but seeing that number I think investors really anchored on, that maybe we've reached a bottom with Google and its advertising rates on mobile.

You see a company that's very cheaply priced, at about 13 times enterprise value to EBITDA because it carries so much cash on its balance sheet. Google, a company clicking on all cylinders. I think the Eric Schmidt stock sale is really just noise.

The more important thing is to focus on the real investment storyline here, which is a company that's performing beautifully today.

Brendan: Real quick. Do you see it as a better value than maybe a cheaper, by-the-book stock, like a Microsoft or an HP, maybe a turnaround play? Do you see their mobile footprint really taking hold there?

Andrew: Yeah, I absolutely do. If you contrast Google, who's really positioning itself to succeed in the mobile future with Android -- they're taking these losses up front so they can succeed -- you contrast that to the old guard at the tech giants, the Microsofts and HPs, and they're the ones that are really struggling.

They're all grasping to break into this space in one way or another. Microsoft's obviously launched its Surface. Now it has Windows, an operating system that can actually operate on a mobile device, but at the same time we're not seeing a lot of traction out of it.

You're seeing that from even some of the mobile plays as well. Nokia (NOK 0.28%) and Research In Motion (BB 1.80%)(now BlackBerry).The smartphone revolution wasn't necessarily a complete out of the blue for them, and they failed to react. Now they're reaping the consequences, really making a concerted effort to break back in, but I think it's going to be really challenging with Google and Apple (AAPL -0.35%) basically holding the de facto market share there.

Brendan: Right. Charlie Munger, what did he say, "Google has the widest moat out of any company I've ever seen"?

Andrew: Yeah, exactly. "I wouldn't want to go up against them." If you gave them the equivalent of Google's market cap, how could you disrupt that? They're such a well-entrenched wide-moat company, you've got to love them as a long-term play.

Brendan: Great. Andrew Tonner, thank you for your time.
