Rumors of Google's (NASDAQ: GOOG) interest in acquiring Twitter have been circulating for months, but the company's CEO says it probably won't happen anytime.

In an interview with Charlie Rose, Eric Schmidt said: "I shouldn't talk about specific acquisitions. We're unlikely to buy anything in the short term, partly because I think prices are still high. And it's unfortunate I think we're in the middle of a cycle. Google is generating a lot of cash. And so we keep that cash in extremely secure banks."

When the CEO of one of the most-watched companies on the planet accelerates his stock sales, people pay attention.

This is what is happening with Google, Inc. (NASDAQ: GOOG) CEO Eric Schmidt, who has sold $1.4 billion worth of stock in under three years with the search king. According to the San Jose Mercury News, "Between Wednesday and Friday, Schmidt filed a series of Form 4s disclosing that he sold 105,739 shares at prices ranging from $563.40 to $571.50 per share to collect $59,968,220."

Is this part of his normally scheduled portfolio divesting strategy, or is Schmidt cashing out before Google shares come crashing down? Although Schmidt, like many execs, sells shares on a scheduled filed with the SEC, we can't judge the guy for Google shares being near the $600 level at this point, right? Although Google shares may come crashing down to reasonable levels at some point, they do stand at over $582 today, within shouting distance of the ill-famed $600 price point. Is Google really worth that much? That question has been bandied about many times recently over the last year, and here we are.

When Schmidt signed on to lead the rag-tag Google team with founders Larry Page and Sergey Brin, he probably had no idea what would transpire. However, the behemoth now controls access to so much information it would boggle the average mind. In a world of instant gratification, Google serves up a tasty dish of information billions of times per day around the world, satisfying the needs of business, government and consumers alike.

For that kind of exponential growth in such a short time, perhaps Schmidt's leadership is worth the billion-plus in stock he's sold since 2005. Is he worth it? You decide.
