After reaching an important support level, NiSource (NI Quick QuoteNI - Free Report) could be a good stock pick from a technical perspective. NI surpassed resistance at the 200-day moving average, suggesting a long-term bullish trend.

The 200-day simple moving average is a useful tool for traders and analysts, establishing market trends for stocks, commodities, indexes, and other financial instruments over the long term. The marker moves higher or lower along with longer-term price moves, and serves as a support or resistance level.

NI could be on the verge of another rally after moving 5.4% higher over the last four weeks. Plus, the company is currently a Zacks Rank #2 (Buy) stock.
