Google cut to 'sell'

You knew this was going to happen. I only regret I sold at $400, not $450

It had to happen one day. An analyst said Google (GOOG, news, msgs) is too expensive.
Scott Devitt, analyst at Stifel, Nicolaus, cut the search-engine company to "sell" from "hold." The fact is that when you purchase a stock, you purchase a business, and Google's cash flow over the next three to five year can't justify the current price, Devitt told CNBC's "Squawk Box."
And it was Yahoo's poor results that indicated the turning point for Google, he said.
"When dealing with a cult stock you have to deal with a change in sentiment," Devitt said. "Yahoo's missed number is a leading indicator for change in online advertising."
Shares of Google sank 3.1% in midday trading.
