Bottom line
ALGN Technical Analysis Summary
ALGN (Align Technology) trades at 173.27, below the short-term moving averages after giving back part of the recovery from the 122.00 low. The daily chart shows price at 173.27 under SMA20 (175.03) and SMA50 (174.15) but above SMA200 (167.15), so the pullback from the April high near 200.44 has turned the short-term structure corrective while the longer recovery above SMA200 remains intact. Daily RSI14 at 48.76 is neutral and the MACD histogram turned negative at -0.36, confirming that near-term momentum has stalled. The weekly chart also shows price at 169.16 below SMA20 (174.32) yet above SMA50 (161.86), and still far below SMA200 (228.60), reflecting the deep multi-year drawdown from the 2021 highs; the five-year return is about -74%. Weekly RSI at 48.12 is neutral and the weekly MACD histogram is negative. Key support rests at 164.74 (20-day low) and 151.58 (60-day low), while resistance sits at 187.96 (20-day high) and 190.97 (60-day high). A close back above SMA20 at 175.03 and a move through 187.96 would restore near-term bullish momentum; a breakdown below 164.74 would open the door to a deeper correction.

Daily (August 4, 2026)
- Trend
- Mixed with a corrective tone. Price at 173.27 trades below SMA20 (175.03, about 1.00% below) and SMA50 (174.15, about 0.51% below) but above SMA200 (167.15, about 3.66% above). The stock pulled back roughly 14% from the April high of 200.44, and the short-term averages no longer support price. The medium-term trend defined by SMA200 remains up, so the daily structure is a pullback inside a longer recovery rather than a new downtrend.
- Momentum
- Neutral with a soft bias. RSI14 at 48.76 sits just below the 50 midline, showing no clear directional conviction. The MACD line at -0.91 is below the signal line at -0.54 with a histogram of -0.36, a negative short-term reading that confirms momentum has cooled since the recent high. Both MACD lines below zero indicate the pullback has been in place for several weeks.
- Volatility
- Moderate. ATR14 at 7.47, about 4.31% of price, reflects normal daily ranges for this stock. Bollinger Bands (166.45 to 183.60) are moderately wide, and price at 173.27 sits below the middle band at 175.03, in the lower half of the bands after the recent decline.
- Volume
- Below average. Latest volume of 789,254 is about 83.5% of the 20-period average of 945,423. The pullback has unfolded on below-average participation, which suggests selling pressure is not aggressive.
Assessment
The daily structure is corrective within a longer recovery. Price is below SMA20 and SMA50, RSI is neutral, and the MACD histogram is negative, all consistent with a pause after the rally toward 200.44. The key levels to watch are support at the 20-day low of 164.74 and SMA200 at 167.15. A hold above these levels keeps the pullback orderly, while a close back above SMA20 at 175.03 would restore near-term bullish momentum.
Weekly (July 27, 2026 week)
- Trend
- Mixed. Price at 169.16 trades below SMA20 (174.32, about 2.96% below) but above SMA50 (161.86, about 4.51% above), while SMA200 at 228.60 remains about 26% overhead. The multi-year decline from the 2021 highs is reflected in the five-year return of about -74%. The recovery off the 122.00 low has been strong, but price has not reclaimed the long-term average.
- Momentum
- Neutral. Weekly RSI14 at 48.12 sits just below the 50 midline. The MACD line at 1.52 is below the signal line at 2.60 with a histogram of -1.08, a modestly negative reading, though both weekly MACD lines remain above zero, so the longer-term momentum has not turned structurally bearish.
- Volatility
- Elevated. Weekly ATR14 at 15.85, about 9.37% of price, reflects wide weekly ranges consistent with a stock that has been through a major repricing. The high ATR percentage warrants position sizing awareness.
- Volume
- Above average. The latest week volume of 6,746,600 is about 131.6% of the 20-week average of 5,126,250, indicating above-average participation during the recent weekly decline.
Assessment
The weekly chart shows a stock recovering from a deep drawdown but still far below its long-term average. Price is above SMA50 but below SMA20 and SMA200. Weekly RSI is neutral and the weekly MACD histogram is negative, so the bounce from the 122.00 low has stalled in recent weeks. A weekly close above SMA20 at 174.32 would improve the picture, while a drop below SMA50 at 161.86 would signal renewed weakness toward the 20-period low near 151.58.

Scenarios
ALGN Technical Scenarios
Conditions, invalidation triggers, and what to watch for each scenario.
Bullish
Trigger
ALGN reclaims and holds above SMA20 at 175.03, then breaks above the 20-day high at 187.96 and the 60-day high at 190.97. A return of daily RSI above 55 and a positive MACD histogram would confirm renewed upward momentum.
Invalidation
A close back below the 20-day low at 164.74 on above-average volume would signal that the correction is deepening.
What to watch
Daily RSI holding above 50; the MACD histogram crossing back above zero; volume expanding on any move through 187.96; price holding above SMA200 at 167.15.
Range-Bound
Trigger
Price consolidates between support at 164.74 and resistance near 187.96 to 190.97 while the market digests the recent pullback. Daily RSI oscillating between 40 and 60 with the MACD hugging its signal line would fit a pause.
Invalidation
A decisive break above 190.97 on strong volume, or a breakdown below 164.74 with expanding selling pressure.
What to watch
RSI staying in the 40 to 60 zone; the MACD histogram hovering near zero; volume staying below average; a clear higher low forming above the 20-day low.
Bearish
Trigger
Price breaks below the 20-day low at 164.74 and then the 60-day low at 151.58, opening the path toward the 52-week low at 122.00.
Invalidation
Price reclaims and holds above SMA50 at 174.15, re-establishing the recovery trend.
What to watch
Daily RSI falling below 40; the MACD histogram turning more negative; volume increasing on down days; price losing SMA200 at 167.15.
