Not yet but they're working on it. Today, the NYSE has moved the issue a great step forward with a proposal to the SEC which if approved, would allow you to see real-time, last-sale prices across all Google properties including Google Finance, Personalized Google, Mobile, and of course, Google.com.

What's really important is getting free, easy and fast access to real-time quotes so you know how the market or your company is doing now, not as of twenty minutes ago.

As a result, we've worked with the SEC, the New York Stock Exchange (NYSE) and our D.C. trade association, NetCoalition, to find a way to bring stock data to Google users in a way that benefits users and is practical for all parties. We have encouraged the SEC to ensure that this data can be made available to our users at fair and reasonable rates, and applaud their recent efforts to review this issue.

You'll have free, easy and fast access to real-time prices from NYSE on Google.
