Zoom Video Communications (ZM Quick QuoteZM - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, ZM crossed above the 20-day moving average, suggesting 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.

Shares of ZM have been moving higher over the past four weeks, up 10%. Plus, the company is currently a Zacks Rank #3 (Hold) stock, suggesting that ZM could be poised for a continued surge.

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 1 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.
