After reaching an important support level, Tactile Systems Technology (TCMD Quick QuoteTCMD - Free Report) could be a good stock pick from a technical perspective. TCMD surpassed resistance at the 20-day moving average, suggesting 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.

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.

Over the past four weeks, TCMD has gained 11.7%. The company is currently ranked a Zacks Rank #2 (Buy), another strong indication the stock could move even higher.

The bullish case solidifies once investors consider TCMD's positive earnings estimate revisions. No estimate has gone lower in the past two months for the current fiscal year, compared to 1 higher, while the consensus estimate has increased too.

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