Hecla Mining (HL Quick QuoteHL - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, HL broke through the 20-day moving average, which 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.

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.

Shares of HL have been moving higher over the past four weeks, up 6%. Plus, the company is currently a Zacks Rank #1 (Strong Buy) stock, suggesting that HL could be poised for a continued surge.

Once investors consider HL's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 2 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

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