BJ's Wholesale Club (BJ Quick QuoteBJ - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, BJ broke through the 20-day moving average, which suggests 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 BJ have been moving higher over the past four weeks, up 11.4%. Plus, the company is currently a Zacks Rank #1 (Strong Buy) stock, suggesting that BJ could be poised for a continued surge.

The bullish case only gets stronger once investors take into account BJ's positive earnings estimate revisions. There have been 7 revisions higher for the current fiscal year compared to none lower, and the consensus estimate has moved up as well.

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