From a technical perspective, VirTra, Inc. (VTSI Quick QuoteVTSI - Free Report) is looking like an interesting pick, as it just reached a key level of support. VTSI 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.

The 20-day moving average can show signals that are similar to other SMAs as well. 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.

VTSI could be on the verge of another rally after moving 8.8% higher over the last four weeks. Plus, the company is currently a Zacks Rank #1 (Strong Buy) stock.

Once investors consider VTSI's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 1 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 VTSI for more gains in the near future.
