Knight-Swift Transportation Holdings (KNX Quick QuoteKNX - Free Report) shares soared 5.1% in the last trading session to close at $49.72. The move was backed by solid volume with far more shares changing hands than in a normal session. This compares to the stock's 0.1% loss over the past four weeks.

The stock rose for the second consecutive day following its acquisition of Dothan, AL-based less-than-truckload ("LTL") carrier AAA Cooper Transportation for an enterprise value of $1.35 billion, which marks the company’s foray into the LTL market.

This trucking company is expected to post quarterly earnings of $0.87 per share in its upcoming report, which represents a year-over-year change of +52.6%. Revenues are expected to be $1.27 billion, up 19.7% 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 Knight-Swift, the consensus EPS estimate for the quarter has been revised 0.6% lower over the last 30 days to the current level. And a negative trend in earnings estimate revisions doesn't usually translate into price appreciation. So, make sure to keep an eye on KNX going forward to see if this recent jump can turn into more strength down the road.
