Schlumberger (SLB Quick QuoteSLB - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, SLB crossed above the 20-day moving average, suggesting a short-term bullish trend.

The 20-day simple moving average is a popular trading tool. It provides a look back at a stock's price over a 20-day period, and is beneficial to short-term traders since it smooths out price fluctuations and provides more trend reversal signals than longer-term moving averages.

Similar to other SMAs, if a stock's price moves above the 20-day, the trend is considered positive, while price falling below the moving average can signal a downward trend.

Shares of SLB have been moving higher over the past four weeks, up 9.1%. Plus, the company is currently a Zacks Rank #2 (Buy) stock, suggesting that SLB could be poised for a continued surge.

Looking at SLB's earnings estimate revisions, investors will be even more convinced of the bullish uptrend. There have been 11 revisions higher for the current fiscal year compared to none lower, and the consensus estimate has moved up as well.

Given this move in earnings estimate revisions and the positive technical factor, investors may want to keep their eye on SLB for more gains in the near future.
