Pro-Dex, Inc. (PDEX) shares rallied 23% in the last trading session to close at $57.78. This move can be attributable to notable volume with a higher number of shares being traded than in a typical session. This compares to the stock's 12.6% loss over the past four weeks.

The sharp upsurge in PDEX shares can be attributed to positive market sentiment surrounding its strong recent financial performance and sustained strength in its business model. The company has shown impressive growth, with past six months return of more than 200%. Investors seem to be optimistic about ProDex’s strong fundamentals and revenue growth, which have been consistent and also likely to reflect in the upcoming results as well.

This company is expected to post quarterly earnings of $0.38 per share in its upcoming report, which represents a year-over-year change of +171.4%. Revenues are expected to be $13.8 million, up 9.6% from the year-ago quarter.

While earnings and revenue growth expectations are important in evaluating the potential strength in a stock, empirical research shows a strong correlation between trends in earnings estimate revisions and 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. So, make sure to keep an eye on PDEX going forward to see if this recent jump can turn into more strength down the road.
