Amer Sports Soars 11.51% To $41.48 On Technical Breakout Momentum

Amer Sports (AS) closed at $41.48 on August 22, 2025, surging 11.51% with a three-day cumulative gain of 16.06%. This robust rally follows a period of consolidation and establishes a new local high of $41.56. The technical landscape is assessed below using multiple methodologies.
Candlestick Theory
Recent candlestick patterns reveal a decisive bullish reversal. The August 19 hammer candle ($35 low, $37.33 close) signaled exhaustion near the $35 support after a 9% decline. This was followed by three consecutive bullish candles, culminating in an August 22 marubozu-like candle (open $37.81, close $41.48) with minimal upper shadow—indicating sustained buying pressure. Key resistance now rests at $41.56 (recent high), while $37.81 serves as immediate support. A confirmed close above $41.56 may extend the uptrend.
Moving Average Theory
The 50-day MA (currently near $37.50) crossed bullishly above the 100-day MA (~$36.80) in early August, confirming a medium-term trend reversal. The August 22 close ($41.48) decisively breached the 200-day MA (~$38.20), shifting this level to support. The current price holding above all three key MAs (50/100/200) signals strengthening bullish momentum. However, the sharp deviation from the 50-day MA (~9% gap) suggests potential near-term consolidation.
MACD & KDJ Indicators
The MACD (12,26,9) shows a bullish crossover in early August, with the histogram expanding positively since August 20—reinforcing upward momentum. KDJ indicators align: The %K (87) and %D (79) are near overbought territory but maintain upward trajectories, supporting continuation strength. Both oscillators lack bearish divergence, suggesting no immediate reversal pressure despite overbought readings. Confluence exists in their shared uptrend confirmation.
Bollinger Bands
Bollinger Bands (20-day) contracted sharply ahead of the August 20–22 breakout, reflecting volatility compression and pent-up energy. Price pierced the upper band ($39.50 approximation) on August 22, closing near its high—a sign of strong trend initiation. Band expansion now underway validates volatility resurgence. While technically overextended, the absence of reversal candles tempers bearish implications near-term.
Volume-Price Relationship
Volume surged 126% to 9.37M shares on August 22 versus the 20-day average (4.2M), decisively confirming the breakout’s legitimacy. This follows two sessions of declining volume during consolidation (August 20–21), highlighting accumulation before the breakout. Volume distribution shows accumulation near $35–37 support, providing a technical foundation for the rally.
Relative Strength Index (RSI)
The 14-day RSI spiked to 78 on August 22, entering overbought territory. Historically, RSI >80 (seen in May/June 2025 rallies) preceded brief pullbacks. However, strong volume and MACD momentum currently mitigate reversal risks. Traders should monitor for RSI divergence or rejection at the $41.56 resistance. The oversold reading of 31 on August 19 adds credibility to the recent reversal.
Fibonacci Retracement
Applying Fibonacci to the June 30 high ($40.21) and August 19 low ($35.00): The 61.8% retracement ($38.22) was breached as support-turned-resistance during the August 20–22 rally. The breakout above the 100% level ($40.21) projects upside toward 138.2% ($42.20). This aligns with volume-supported momentum, though exhaustion may emerge near $42.20–42.50.
Confluence and Divergence
Strong confluence exists: Moving average alignment, MACD/KDJ momentum confirmation, volume-backed breakout, and Fibonacci projection collectively endorse bullish momentum. No material divergences are evident. However, RSI overbought conditions and Bollinger Band extension advise caution if $41.56 resistance holds. Probabilistically, a close above $41.56 may target $42.20–42.50, while failure to hold $40.20 could signal consolidation toward $38.50.
