After reaching an important support level, Helmerich & Payne (HP Quick QuoteHP - Free Report) could be a good stock pick from a technical perspective. HP 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.

Similar to other SMAs, if a stock's price moves above the 20-day, the trend is considered positive, while price falling below the moving average can signal a downward trend.

HP has rallied 10.5% over the past four weeks, and the company is a Zacks Rank #2 (Buy) at the moment. This combination suggests HP could be on the verge of another move higher.

Once investors consider HP's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 3 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

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