This image, from Dr. John Hussman's weekly market analysis, suggests that this stock market bubble is just getting bigger and bigger. The Dow finished up 9 days in a row today, even though it was already at record highs. Of course, the nature of a bubble is that the vast majority of market participants don't recognize it as such. If they did, extreme prices wouldn't be moving from one extreme to even greater ones.
In the image, the red line is the calculation of a log-period bubble base on the formulas of Dr. Didier Sornette. This bubble matches his calculations perfectly. It is a flawless example of a financial bubble.
