Iridex (IRIX Quick QuoteIRIX - Free Report) shares soared 7.3% in the last trading session to close at $9.37. The move was backed by solid volume with far more shares changing hands than in a normal session. This compares to the stock's 13.8% gain over the past four weeks.

Iridex is riding on strong demand for Cyclo G6 Glaucoma Laser Systems, Cyclo G6 product and Retina product.

This medical laser company is expected to post quarterly loss of $0.15 per share in its upcoming report, which represents a year-over-year change of -25%. Revenues are expected to be $11.9 million, up 35.2% from the year-ago quarter.

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 Iridex, 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 IRIX going forward to see if this recent jump can turn into more strength down the road.
