After reaching an important support level, Tenaris S.A. (TS Quick QuoteTS - Free Report) could be a good stock pick from a technical perspective. TS surpassed resistance at the 20-day moving average, suggesting 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.

TS has rallied 6.7% over the past four weeks, and the company is a Zacks Rank #1 (Strong Buy) at the moment. This combination suggests TS could be on the verge of another move higher.

The bullish case solidifies once investors consider TS's positive earnings estimate revisions. No estimate has gone lower in the past two months for the current fiscal year, compared to 5 higher, while the consensus estimate has increased too.

With a winning combination of earnings estimate revisions and hitting a key technical level, investors should keep their eye on TS for more gains in the near future.
