BOSTON ( TheStreet Ratings) -- The U.S. economy, while making strides since the Great Recession, slowed in the first quarter, and the job market and housing industry have worsened. Higher oil and food prices, Europe's debt woes and the earthquake in Japan piled on to the misery.Still, I wanted to find stocks that have been bucking the trend. Specifically, companies that are increasing profits at a fast rate. I screened top-rated stocks (as ranked by TheStreet Ratings' quantitative equity model) and looked for companies with growth in revenue, earnings and cash flow of at least 20% in the most recent quarter and with estimated growth of at least 20% in earnings per share over the next year. I also wanted companies with so-called high-quality earnings, meaning cash flow is greater than net income. If net income is greater than cash flow, it could be a sign that the company is manipulating profits or using aggressive accounting methods to make earnings look better than they may be. Here are the highest-rated stocks, according to the aforementioned metrics: Carbo Ceramics ( CRR) makes ceramic proppants, which are used in the hydraulic fracturing of natural gas and oil wells. Once a driller has "fractured" the sediment, it needs something to keep it "propped" for gases or liquids to flow more efficiently to the wellhead. Ceramic proppants offer an alternative to popular sand-based materials and have shown to greatly improve the production of oil and gas. Carbo Ceramics has been a big benefactor of exploration in the Eagle Ford and the Haynesville shale territories, setting records for proppant-sales volume in the recent quarter, with earnings and operating cash flow up 44% and 55%, respectively. Management is aggressively building for the future, with two projects that should increase proppant capacity to over 2.1 billion pounds per year, an increase of 35% over current production. Yet, after the stock has more than doubled in the past year, some investors are concerned Carbo Ceramics is overvalued. The stock trades at a premium to the industry (current price-to-earnings ratio of 36 and forward P/E of 23), but, given growth prospects and leadership position in a booming industry, I still think the stock offers a great secular growth opportunity. TheStreet Ratings has a "buy" with a $197 price target (34% potential upside) on shares of Carbo Ceramics.
