Shares of the company practically doubled to approximately 634,000 from the daily average of around 330,000.

Early this month, STAA announced second-quarter earnings per share of 2 cents, which beat the Zacks Consensus Estimate by 100%. (Of course, you could also say that it topped by a penny.) Revenue jumped 19% to $16.3 million.

The big star of the quarter was its Visian ICL product, which is an implantable lens used to correct myopia through refractive surgery. Sales of Visian ICLs were up 41%.

The quarter was so solid that STAA decided to raise its 2011 outlook. As a result, two of four covering analysts raised their estimates in the past 30 days for the year. The Zacks Consensus Estimate has improved by a penny in that time, or more than 16.5%.

The Zacks Consensus Estimate for 2012 has been loitering at 14 cents for months now, but that still suggests year-over-year profit growth of 100%.

PROS Holdings, Inc. (PRO - Snapshot Report) was close behind on Wednesday with a gain of 7.33%, as this management software solutions company also announced a solid quarter in early August.

Earnings per share of 5 cents reversed a year-ago loss and also topped the Zacks Consensus Estimate by 25%. Total revenue increased 33% to $23.8 million.

As for 2012, the Zacks Consensus Estimate has increased 14.3% to 24 cents per share. At the moment, analysts are expecting profit growth of 50% for next year over this year.

Rocky Brands, Inc. (RCKY - Snapshot Report) has watched all the analysts covering its stock raise estimates in the past 30 days. Sure, there are only 2 analysts covering this footwear and apparel company for 2011 and 2012 each, but that's still a positive development.

RCKY has been on a roll. It has put together 8 consecutive quarters with profit that not only improved on a year-over-year basis, but also beat the Zacks Consensus Estimate. It's most recent report from late July is the catalyst for the upward momentum in earnings estimates.

And on Wednesday it became a top-performing Zacks #1 Rank with shares that gained nearly 5.7%.

The second quarter saw earnings per share of 30 cents surpass the Zacks Consensus Estimate by 50%. Net sales declined slightly year over year to $52.3 million due to reduced sales under military contracts.

The company attributes its bottom line growth to increased operating efficiencies, higher gross margins and a reduction in interest expense. Looking forward, RCKY believes it is positioned to drive future earnings through the top line in its wholesale and retail segments.

In addition to all this, the company was recently featured as an Aggressive Growth Stock of the Day on Zacks.com.

The Zacks Consensus Estimate for this year has moved 7% higher in the past month to $1.52 per share. Meanwhile, the Zacks Consensus Estimate for 2012 is up 6.2% to $1.71, which is also 12.5% better than what's currently expected for 2011.
