From a technical perspective, Becton Dickinson (BDX Quick QuoteBDX - Free Report) is looking like an interesting pick, as it just reached a key level of support. BDX recently overtook the 20-day moving average, and this suggests a short-term bullish trend.

The 20-day simple moving average is a well-liked trading tool because it provides a look back at a stock's price over a 20-day period. Additionally, short-term traders find this SMA very beneficial, as it smooths out short-term price trends and shows 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.

BDX could be on the verge of another rally after moving 8.4% higher over the last four weeks. Plus, the company is currently a Zacks Rank #3 (Hold) stock.

The bullish case solidifies once investors consider BDX's positive earnings estimate revisions. No estimate has gone lower in the past two months for the current fiscal year, compared to 2 higher, while the consensus estimate has increased too.

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