Price is above the SMA20 (154.72), SMA50 (144.70), and SMA200 (108.75) on the daily chart, with RSI14 at 61.77 and a positive MACD histogram pointing to healthy upside momentum. The weekly chart is even more constructive, with price at 161.99 above the weekly SMA20 (118.99), SMA50 (100.91), and SMA200 (49.83), and weekly RSI at 69.44, confirming the longer-term trend.

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.

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.
