From a technical perspective, ABB is looking like an interesting pick, as it just reached a key level of support. ABB recently overtook the 20-day moving average, and this suggests a short-term bullish trend.

The 20-day simple moving average is a well-liked trading tool because it provides a look back at a stock's price over a 20-day period. Additionally, short-term traders find this SMA very beneficial, as it smooths out short-term price trends and shows 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.

Over the past four weeks, ABB has gained 5%. The company is currently ranked a Zacks Rank #3 (Hold), another strong indication the stock could move even higher.

Once investors consider ABB's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 3 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

Given this move in earnings estimate revisions and the positive technical factor, investors may want to keep their eye on ABB for more gains in the near future.
