From a technical perspective, Synaptics (SYNA Quick QuoteSYNA - Free Report) is looking like an interesting pick, as it just reached a key level of support. SYNA recently overtook the 20-day moving average, and this suggests a short-term bullish trend.

The 20-day simple moving average is a popular investing tool. Traders like this SMA because it offers a look back at a stock's price over a shorter period and helps smooth out price fluctuations. The 20-day can also show 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 SYNA have been moving higher over the past four weeks, up 22.1%. Plus, the company is currently a Zacks Rank #1 (Strong Buy) stock, suggesting that SYNA could be poised for a continued surge.

The bullish case only gets stronger once investors take into account SYNA'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 SYNA on their watchlist given the ultra-important technical indicator and positive move in earnings estimate revisions.
