Merck (MRK Quick QuoteMRK - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, MRK broke out above the 50-day moving average, suggesting a short-term bullish trend.

The 50-day simple moving average is a widely used technical indicator that helps determine support or resistance levels for different types of securities. It's one of three major moving averages, but takes precedent because it's the first sign of an up or down trend.

MRK has rallied 7.1% over the past four weeks, and the company is a Zacks Rank #3 (Hold) at the moment. This combination suggests MRK could be on the verge of another move higher.

Once investors consider MRK's positive earnings estimate revisions, the bullish case only solidifies. No estimate has gone lower in the past two months for the current fiscal year, compared to 5 higher, and the consensus estimate has increased as well.

With a winning combination of earnings estimate revisions and hitting a key technical level, investors should keep their eye on MRK for more gains in the near future.
