From a technical perspective, Regeneron (REGN Quick QuoteREGN - Free Report) is looking like an interesting pick, as it just reached a key level of support. REGN recently overtook the 20-day moving average, and this suggests 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 REGN have been moving higher over the past four weeks, up 7.5%. Plus, the company is currently a Zacks Rank #3 (Hold) stock, suggesting that REGN could be poised for a continued surge.

Investors should think about putting REGN on their watchlist given the ultra-important technical indicator and positive move in earnings estimate revisions.
