The uptrend can be attributable to strengthening demand in its core display solutions and lighting markets, targeted price actions, domestic manufacturing footprint, and robust order fulfillment capabilities.

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 LSI, the consensus EPS estimate for the quarter has been revised 6.3% higher over the last 30 days to the current level. And a positive trend in earnings estimate revision usually translates into price appreciation. So, make sure to keep an eye on LYTS going forward to see if this recent jump can turn into more strength down the road.
