From a technical perspective, Schlumberger (SLB Quick QuoteSLB - Free Report) is looking like an interesting pick, as it just reached a key level of support. SLB recently overtook the 50-day moving average, and this suggests a short-term bullish trend.

The 50-day simple moving average, which is one of three major moving averages, is widely used by traders and analysts to establish support and resistance levels for a range of securities. Because it's the first sign of an up or down trend, the 50-day is considered to be more important.

Over the past four weeks, SLB has gained 15%. The company is currently ranked a Zacks Rank #2 (Buy), another strong indication the stock could move even higher.
