Impinj PI shares rallied 5.1% in the last trading session to close at $149.83. 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 24.3% loss over the past four weeks.

Impinj is benefiting from strength in the end-point IC product line, which is driving its momentum in retail apparel and general merchandise applications.

This provider of radio frequency identification products is expected to post quarterly earnings of $0.47 per share in its upcoming report, which represents a year-over-year change of +422.2%. Revenues are expected to be $92.8 million, up 31.4% 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 Impinj, 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 PI going forward to see if this recent jump can turn into more strength down the road.
