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

RMBS has rallied 13.1% over the past four weeks, and the company is a Zacks Rank #3 (Hold) at the moment. This combination suggests RMBS could be on the verge of another move higher.

Once investors consider RMBS's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 2 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

Investors may want to watch RMBS for more gains in the near future given the company's key technical level and positive earnings estimate revisions.
