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

The 20-day simple moving average is a well-liked trading tool because it provides a look back at a stock's price over a 20-day period. Additionally, short-term traders find this SMA very beneficial, as it smooths out short-term price trends and shows more trend reversal signals than longer-term moving averages.

Similar to other SMAs, if a stock's price moves above the 20-day, the trend is considered positive, while price falling below the moving average can signal a downward trend.

IAG has rallied 36.4% over the past four weeks, and the company is a Zacks Rank #1 (Strong Buy) at the moment. This combination suggests IAG could be on the verge of another move higher.

Once investors consider IAG's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 5 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

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