Blackstone Group (BX) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, BX 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 BX have been moving higher over the past four weeks, up 5.5%. Plus, the company is currently a Zacks Rank #2 (Buy) stock, suggesting that BX could be poised for a continued surge.Looking at BX's earnings estimate revisions, investors will be even more convinced of the bullish uptrend.
