Amtech Systems (ASYS Quick QuoteASYS - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, ASYS 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.

Over the past four weeks, ASYS has gained 11.2%. The company is currently ranked a Zacks Rank #1 (Strong Buy), another strong indication the stock could move even higher.

The bullish case solidifies once investors consider ASYS's positive earnings estimate revisions. No estimate has gone lower in the past two months for the current fiscal year, compared to 1 higher, while the consensus estimate has increased too.

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