AppFolio (APPF Quick QuoteAPPF - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, APPF crossed above the 20-day moving average, suggesting a short-term bullish trend.

The 20-day simple moving average is a popular trading tool. It provides a look back at a stock's price over a 20-day period, and is beneficial to short-term traders since it smooths out price fluctuations and provides 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.

APPF has rallied 11.2% over the past four weeks, and the company is a Zacks Rank #1 (Strong Buy) at the moment. This combination suggests APPF could be on the verge of another move higher.

The bullish case only gets stronger once investors take into account APPF's positive earnings estimate revisions. There have been 4 revisions higher for the current fiscal year compared to none lower, and the consensus estimate has moved up as well.

Investors should think about putting APPF on their watchlist given the ultra-important technical indicator and positive move in earnings estimate revisions.
