After reaching an important support level, Lam Research (LRCX Quick QuoteLRCX - Free Report) could be a good stock pick from a technical perspective. LRCX surpassed resistance at the 20-day moving average, suggesting a short-term bullish trend.

The 20-day simple moving average is a popular investing tool. Traders like this SMA because it offers a look back at a stock's price over a shorter period and helps smooth out price fluctuations. The 20-day can also show 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 LRCX have been moving higher over the past four weeks, up 6.4%. Plus, the company is currently a Zacks Rank #3 (Hold) stock, suggesting that LRCX could be poised for a continued surge.

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