After reaching an important support level, Sigma Lithium Corporation (SGML Quick QuoteSGML - Free Report) could be a good stock pick from a technical perspective. SGML surpassed resistance at the 50-day moving average, suggesting a short-term bullish trend.

The 50-day simple moving average is one of three major moving averages used by traders and analysts to determine support or resistance levels for a wide range of securities. But the 50-day is considered to be more important because it's the first marker of an up or down trend.

SGML has rallied 16.4% over the past four weeks, and the company is a Zacks Rank #3 (Hold) at the moment. This combination suggests SGML could be on the verge of another move higher.

Once investors consider SGML's positive earnings estimate revisions, the bullish case only solidifies. No estimate has gone lower in the past two months for the current fiscal year, compared to 1 higher, and the consensus estimate has increased as well.

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