Europe is starting to buzz again, according to a report published today. A purchasing managers index (PMI) released by research company Markit came in at 51.7 for the euro zone, which was 0.8 higher than expected. Anything above 50 is positive, showing an expansion of activity. Last week, it was announced that European GDP grew 0.3% in the second quarter of 2013.

Meanwhile, a similar index in China also shows some good economic news for the world's most populous country. A PMI focusing on small and mid-sized Chinese companies compiled by HSBC came in at 50.1 for the month of July. China's official PMI, skewed towards larger and state-run companies is 50.3.
Blaze Tankersley, Senior Managing Direct at BayCrest Partners, believes there's one sector to buy into on improved European and Chinese data: oil service companies. "Oil is real and will respond to growth," writes Tankersley in his most recent report, "while copper, iron ore, and coal shares are not likely to do so in my opinion."
But is he right? And, if so, what names should an investor look at?
Drilling into the fundamentals for Talking Numbers is Steve Cortes, founder of Veracruz TJM. He looks at the oil companies in light of improved Chinese and European data to determine if they're a good buy.
