From a technical perspective, Monolithic Power (MPWR Quick QuoteMPWR - Free Report) is looking like an interesting pick, as it just reached a key level of support. MPWR recently overtook the 50-day moving average, and this suggests a short-term bullish trend.

The 50-day simple moving average, which is one of three major moving averages, is widely used by traders and analysts to establish support and resistance levels for a range of securities. Because it's the first sign of an up or down trend, the 50-day is considered to be more important.

MPWR could be on the verge of another rally after moving 15.1% higher over the last four weeks. Plus, the company is currently a Zacks Rank #3 (Hold) stock.

The bullish case solidifies once investors consider MPWR'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.
