Daily (August 5, 2026)

Trend
Bullish. Price at 163.18 is above the SMA20 (154.72), the SMA50 (144.70), and the SMA200 (108.75). The moving averages are stacked in a rising alignment, with the SMA200 well below price reflecting the strong uptrend that built over the past year. Price is trading near the upper Bollinger Band, consistent with an established uptrend.
Momentum
Positive. RSI14 at 61.77 is above 50 and comfortably above the 60 level, showing strong but not yet overbought momentum. The MACD line at 3.60 is above the signal line at 3.36, and the histogram at 0.23 is positive, confirming upward momentum on the daily chart.
Volatility
Moderate. ATR14 at 8.48 equals 5.19% of price, reflecting meaningful but not extreme daily swings for a biotechnology name. Bollinger Bands (141.58 to 167.86) are reasonably wide, and price at 163.18 is trading near the upper band, consistent with the strong trend.
Volume

Assessment

The daily chart is bullish. Price sits above all major moving averages and near the upper Bollinger Band, RSI is above 60, and the MACD is positive. Key support is the SMA20 at 154.72, followed by the 20-period low at 140.86. Resistance is the 52-week and 20-period high at 176.58. A decisive close above 176.58 would extend the uptrend, while a close below the SMA20 zone would be the first warning sign of a pullback.

Volatility
Elevated. Weekly ATR14 at 15.89 equals 9.81% of price, reflecting wide weekly ranges in this high-growth diagnostics company. Bollinger Bands (59.13 to 178.85) are very wide, highlighting how far the stock has moved in both directions over the past five years.
Volume
Slightly above average. Latest weekly volume of 12,931,000 is 1.10 times the 20-week average (11,806,260), indicating healthy participation in the most recent completed week.
