Amer Sports Surges 3.35% Amid Volatile Week as Technical Analysis Flags Potential Consolidation After 5.41% Rally and 3.24% Drop

Amer Sports (AS) experienced a 3.35% increase in the most recent trading session, closing at ¥39.81 after a volatile week that included a 5.41% surge on February 9 and a 3.24% decline the following day. This price action suggests short-term momentum but also highlights potential consolidation. Below is a technical analysis using multiple frameworks to assess the stock’s near-term outlook.

Candlestick Theory

Recent candlestick patterns indicate mixed signals. A bullish engulfing pattern emerged on February 9 (5.41% gain), followed by a bearish harami on February 12 (3.24% drop), suggesting indecision. Key support levels are identified at ¥35.73 (February 5 close) and ¥34.06 (November 21 low), while resistance lies at ¥40.61 (February 12 high) and ¥41.31 (February 11 high). The price has tested the ¥38.18–39.9 range repeatedly, with a potential breakout above ¥40.61 likely to validate bullish momentum.

Moving Average Theory

Short-term moving averages (50-day at ~¥36.50, 100-day at ~¥34.80) are above the 200-day (~¥33.20), confirming an uptrend. However, the 50-day MA has flattened recently, indicating weakening momentum. The stock closed above its 50-day MA for the third consecutive session, suggesting buyers are entering, but the 200-day MA remains a critical baseline for trend sustainability. A break below ¥36.50 could trigger a retest of the 200-day MA.

MACD & KDJ Indicators

The MACD histogram turned positive on February 9, aligning with the bullish engulfing pattern, but has since contracted, signaling waning momentum. The KDJ oscillator shows stochastics at overbought levels (K=85, D=78), with a bearish crossover likely in the near term. This divergence between MACD contraction and overbought stochastics raises caution about a potential pullback.

Bollinger Bands

Volatility has expanded recently, with the 20-period Bollinger Bands widening to a range of ¥38.18–41.23. The price closed near the upper band on February 13, a classic overbought signal. If the bands contract, it may precede a breakout or breakdown; however, the current position near the upper band suggests a short-term correction is probable.

Volume-Price Relationship
Trading volume surged on February 9 (8.39M shares) during the 5.41% rally, validating the move. However, volume dropped on February 13 (3.34M shares) despite the 3.35% gain, indicating weakening conviction. A sustained increase in volume above 5M shares would be necessary to confirm a breakout above ¥40.61, while declining volume during rallies may signal exhaustion.

Relative Strength Index (RSI)

The 14-day RSI reached 68 on February 13, nearing overbought territory. While not yet at 70, this level suggests short-term overextension. A close below 50 would indicate bearish momentum, with potential support at 40–45. The RSI divergence with price (rising RSI vs. flattening price) implies caution, as overbought conditions often precede corrections.

Fibonacci Retracement

Applying Fibonacci levels from the recent high of ¥41.31 (February 11) to the low of ¥34.06 (November 21), key retracement levels at ¥38.21 (38.2%), ¥36.34 (50%), and ¥35.28 (61.8%) are critical. The current price of ¥39.81 is testing the 38.2% level, which could act as a magnet for buyers. A break above ¥41.31 would target ¥42.45 (extension level), but a failure to hold ¥38.21 may lead to a retest of ¥36.34.

Confluence and Divergences

Confluence exists between the 50-day MA and Fibonacci 38.2% level (~¥38.21), offering a key support zone. However, divergences between MACD contraction and overbought RSI/stochastics suggest caution. The volume-Price relationship also highlights weak confirmation during recent rallies, increasing the likelihood of a near-term pullback. While the uptrend remains intact, a consolidation phase below ¥40.61 is probable unless volume surges to validate higher prices.
