Bottom line

GRMN Technical Analysis Summary

GRMN shows a cautiously bullish picture. Price trades above SMA20 and SMA50 on both daily and weekly timeframes, with the SMA200 sloping upward confirming the long-term uptrend. RSI near 55 on both frames is neutral, suggesting neither overbought nor oversold conditions. The daily MACD histogram is positive and rising, signaling short-term bullish momentum. However, the weekly MACD histogram is negative, indicating a divergence between timeframes. Price sits at 65.7% of its 52-week range, leaving room for upside. Key support is at the 20-day low of 228.51 and the 60-day low of 223.55. Resistance is at the 52-week high of 273.32.

Comparing daily (2-year) and weekly (5-year) perspectives to identify aligned or conflicting signals.

Daily (July 13, 2026)

Trend
Bullish. Price at 243.61 is above SMA20 (238.73), SMA50 (237.29), and SMA200 (227.34). The SMA20 is above SMA50, confirming a short-term bullish alignment. The SMA200 is sloping upward, supporting the long-term uptrend.
Momentum
Neutral-Bullish. RSI14 at 55.73 is in neutral territory, showing neither overbought nor oversold conditions. Daily MACD line at 1.92 is above the signal line at 1.04 with a positive rising histogram of 0.88, indicating building bullish momentum.
Volatility
Moderate. ATR14 at 6.22 (2.55% of price) suggests an average daily movement of about 2.6%. Bollinger Bands (229.60 to 247.86) show price near the middle band, reflecting neutral volatility.
Volume
Below average. Latest volume of 532,900 is 58.3% of the 20-period average (914,180), indicating reduced participation.

Assessment

The daily chart shows a neutral to slightly bullish picture. Price holds above all key SMAs with a bullish alignment, and RSI at 55 provides room for movement in either direction. The rising daily MACD histogram is a positive sign. However, below-average volume raises questions about conviction. A move above the 20-day high of 250.34 would strengthen the bullish case.

Weekly (July 6, 2026 week)

Trend
Bullish. Price at 243.11 is above SMA20 (240.11), SMA50 (227.14), and SMA200 (161.44). The SMA200 is sloping strongly upward, confirming a mature long-term uptrend.
Momentum
Neutral. RSI14 at 55.42 is neutral. Weekly MACD line at 4.08 is below the signal line at 5.03 with a negative histogram of -0.95, indicating fading upside momentum on the weekly scale.
Volatility
Moderate. ATR14 at 14.09 (5.80% of price) reflects normal weekly ranges.
Volume
Below average. Weekly volume of 3,020,300 is 76.5% of the 20-week average (3,948,445).

Assessment

The weekly chart confirms a long-term uptrend with price above all key SMAs, especially the strongly rising SMA200. However, the negative MACD histogram is a cautionary signal that bullish momentum is fading on the weekly scale. The neutral RSI provides flexibility. The stock is at 65% of its 52-week range, not overextended. The divergence between daily (positive MACD) and weekly (negative MACD) suggests the current trend is intact but may face headwinds.
