Quidel (QDEL Quick QuoteQDEL - Free Report) is looking like an interesting pick from a technical perspective, as the company reached a key level of support. Recently, QDEL crossed above the 20-day moving average, suggesting 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.
