From a technical perspective, Heico Corporation (HEI Quick QuoteHEI - Free Report) is looking like an interesting pick, as it just reached a key level of support. HEI 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.

HEI could be on the verge of another rally after moving 8.2% higher over the last four weeks. Plus, the company is currently a Zacks Rank #1 (Strong Buy) stock.

The bullish case only gets stronger once investors take into account HEI's positive earnings estimate revisions. There have been 5 revisions higher for the current fiscal year compared to none lower, and the consensus estimate has moved up as well.

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