Pro-Dex, Inc. (PDEX) shares soared 7.4% in the last trading session to close at $55.19. The move was backed by solid volume with far more shares changing hands than in a normal session. This compares to the stock's 49.8% gain over the past four weeks.

Earnings and revenue growth expectations certainly give a good sense of the potential strength in a stock, but empirical research shows that trends in earnings estimate revisions are strongly correlated with near-term stock price movements.

For ProDex, the consensus EPS estimate for the quarter has remained unchanged over the last 30 days. And a stock's price usually doesn't keep moving higher in the absence of any trend in earnings estimate revisions.
