From a technical perspective, Northrop Grumman (NOC) is looking like an interesting pick, as it just reached a key level of support. NOC recently overtook the 20-day moving average, and this 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. 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.
