From a technical perspective, Nvidia (NVDA Quick QuoteNVDA - Free Report) is looking like an interesting pick, as it just reached a key level of support. NVDA 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.

Over the past four weeks, NVDA has gained 5.8%. The company is currently ranked a Zacks Rank #2 (Buy), another strong indication the stock could move even higher.

Once investors consider NVDA's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 11 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

With a winning combination of earnings estimate revisions and hitting a key technical level, investors should keep their eye on NVDA for more gains in the near future.
