Bottom line
DXCM Technical Analysis Summary
DXCM has surged after its second-quarter earnings release, and the daily chart is strongly bullish: price at 87.31 is above SMA20 (75.30), SMA50 (73.45), and SMA200 (67.85), MACD is accelerating, and volume is above average. The stock sits just below its 52-week high of 87.63. However, the daily RSI at 72.64 and a close above the upper Bollinger Band signal an extended move with pullback risk. The weekly chart confirms the recovery, with price above SMA20 (68.96) and SMA50 (68.53), but it remains about 10.5% below the declining SMA200 at 93.20. Key resistance is at 87.63, followed by 89.98. Support rests at 75.30 (SMA20) and 69.79 (20-day low). A weekly close above SMA200 would be the strongest confirmation of a long-term trend change.

Daily (August 3, 2026)
- Trend
- Bullish. Price at 87.31 is above SMA20 (75.30), SMA50 (73.45), and SMA200 (67.85). The SMA20 is above SMA50 above SMA200, a fully aligned short-term bullish stack, and the SMA200 is sloping upward, supporting the intermediate-term uptrend.
- Momentum
- Strong but overbought. RSI14 at 72.64 is above the 70 overbought threshold after the sharp rally. MACD at 2.23 with signal at 1.14 and a rising histogram of 1.10 shows accelerating bullish momentum, though the overbought RSI suggests the move is extended in the short term.
- Volatility
- Elevated. ATR14 at 3.26 (3.73% of price) reflects above-average daily movement. Bollinger Bands (67.61 to 82.99) are wide, and price is trading above the upper band, reflecting strong upward momentum and potential short-term overextension.
- Volume
- Above average. Latest volume of 9,190,000 is 180.7% of the 20-period average (5,084,850), confirming strong participation in the advance.
Assessment
The daily chart is strongly bullish after a post-earnings surge. Price at 87.31 is above all key moving averages and just below the 52-week high of 87.63. MACD is accelerating and volume is above average. However, RSI at 72.64 and a close above the upper Bollinger Band indicate an extended short-term move with pullback risk. Key resistance is the 52-week high at 87.63, followed by 89.98 on the weekly chart. Support rests at the SMA20 of 75.30 and the 20-day low of 69.79.
Weekly (July 27, 2026 week)
- Trend
- Mixed but improving. Price at 83.45 is above SMA20 (68.96) and SMA50 (68.53) but below SMA200 (93.20). The SMA200 is still sloping downward, confirming the long-term trend has not yet reversed, though the strong short-term recovery is narrowing the gap.
- Momentum
- Bullish. RSI14 at 64.86 is in healthy bullish territory, below the overbought threshold. MACD at 2.40 with signal at 1.05 and a rising histogram of 1.35 shows building bullish momentum on the weekly scale.
- Volatility
- Elevated. ATR14 at 6.07 (7.28% of price) reflects wide weekly ranges, typical of a stock in a strong recovery phase.
- Volume
- Above average. Weekly volume of 33,019,600 is 130.8% of the 20-week average (25,236,595), showing strong participation during the rally.
Assessment
The weekly chart shows a strong recovery within a still mixed long-term structure. The week ending July 31 gained 16.65%, pushing price above SMA20 (68.96) and SMA50 (68.53) and to the top of the 52-week range at 95.91%. MACD is rising and volume is above average. However, price remains about 10.5% below the declining SMA200 at 93.20. A sustained weekly close above SMA200 would be needed to confirm a long-term trend reversal. Until then, this is a strong recovery within a longer-term downtrend.
