From a technical perspective, Steel Dynamics (STLD Quick QuoteSTLD - Free Report) is looking like an interesting pick, as it just reached a key level of support. STLD 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.

Like other SMAs, if a stock's price is moving above the 20-day, the trend is considered positive. When the price falls below the moving average, it can signal a downward trend.

STLD has rallied 9.2% over the past four weeks, and the company is a Zacks Rank #1 (Strong Buy) at the moment. This combination suggests STLD could be on the verge of another move higher.

Once investors consider STLD's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 4 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

Investors may want to watch STLD for more gains in the near future given the company's key technical level and positive earnings estimate revisions.
