PubMatic, Inc. (PUBM Quick QuotePUBM - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, PUBM 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.

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.

PUBM has rallied 17.5% over the past four weeks, and the company is a Zacks Rank #2 (Buy) at the moment. This combination suggests PUBM could be on the verge of another move higher.
