Zoom Video Communications (ZM Quick QuoteZM - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, ZM broke through the 20-day moving average, which suggests a short-term bullish trend.

A well-liked tool among traders, the 20-day simple moving average offers a look back at a stock's price over a 20-day period. This is very beneficial to short-term traders, as it smooths out short-term price trends and gives more trend reversal signals than longer-term moving averages.

The 20-day moving average can show signals that are similar to other SMAs as well. 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, ZM has gained 16.4%. The company is currently ranked a Zacks Rank #3 (Hold), another strong indication the stock could move even higher.

The bullish case solidifies once investors consider ZM's positive earnings estimate revisions. No estimate has gone lower in the past two months for the current fiscal year, compared to 10 higher, while the consensus estimate has increased too.

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