Fluor (FLR) shares soared 7.6% in the last trading session to close at $17.21. The move was backed by solid volume with far more shares changing hands than in a normal session. This compares to the stock's 17.3% loss over the past four weeks.Shares of Fluor jumped probably due to increased optimism over the company's focus on new strategy, “Building a Better Future,” within which it has outlined four strategic priorities for driving shareholders’ value. Also, growth opportunities in renewable energy, gas-fired combined cycle generation and air emissions compliance projects for existing coal-fired power plants bode well.This engineering, construction and operations company is expected to post quarterly earnings of $0.10 per share in its upcoming report, which represents a year-over-year change of +162.5%. Revenues are expected to be $3.31 billion, down 19% 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 Fluor, 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 FLR going forward to see if this recent jump can turn into more strength down the road.The stock currently carries a Zacks Rank 3 (Hold).
