From a technical perspective, Twilio (TWLO Quick QuoteTWLO - Free Report) is looking like an interesting pick, as it just reached a key level of support. TWLO recently overtook the 20-day moving average, and this 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.

TWLO could be on the verge of another rally after moving 13.3% higher over the last four weeks. Plus, the company is currently a Zacks Rank #3 (Hold) stock.

The bullish case solidifies once investors consider TWLO's positive earnings estimate revisions. No estimate has gone lower in the past two months for the current fiscal year, compared to 8 higher, while the consensus estimate has increased too.

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