KB Financial Group Stock Surges 9.29% to 80.14 Amid Strong Technical Momentum

KB Financial Group has demonstrated significant bullish momentum recently, with its stock price surging 9.29% on June 4, 2025, closing at 80.14 after reaching an intraday high of 80.33. This follows a 0.12% gain on June 3, resulting in a two-day rally of 9.42%. The analysis below examines key technical indicators to contextualize this movement and identify probable future price behavior.
Candlestick Theory
The June 4 session formed a robust bullish candle with minimal upper wick, closing near the daily high of 80.33, indicating strong buying conviction. This follows a bullish engulfing pattern emerging from June 2–3, where the 0.12% gain on June 3 fully consumed the prior session’s bearish body (-2.02%). Immediate resistance is evident at 80.33–80.50, a psychological barrier tested but not surpassed. Support rests at 78.25 (June 4 low), aligning with the June 3 swing high of 73.96. A decisive break above 80.50 could signal continuation toward 82.00, while failure to hold 78.25 may trigger profit-taking toward 75.14 (May 30 high).
Moving Average Theory
The 50-day, 100-day, and 200-day moving averages (MAs) exhibit a bullish alignment, with the price (80.14) trading well above all three. The 50-day MA (≈63.20) has recently crossed above the 100-day MA (≈60.80), confirming a bullish golden cross. This structure underscores a strong intermediate-term uptrend, further validated by the ascending 200-day MA (≈58.40). The widening gap between short and long-term MAs suggests accelerating momentum, though a pullback toward 76.00 (near the 50-day MA) could materialize as a mean-reversion opportunity if volatility increases.
MACD & KDJ Indicators
The MACD (12,26,9) shows a strengthening bullish crossover, with the histogram expanding above the zero line since late May, confirming upward momentum. Meanwhile, the KDJ oscillator (14,3,3) presents a nuanced signal: %K (89) and %D (85) have entered overbought territory (>80) following the surge. While this typically flags exhaustion risk, the maintained separation between %K and %D lines suggests ongoing momentum. Divergence is absent, but traders should monitor for %K reversals below %D as a warning of short-term consolidation. The MACD-KDJ confluence supports near-term bullishness, though overbought KDJ readings advise caution.
Bollinger Bands
Bollinger Bands (20-day, 2σ) highlight expanding volatility, with the June 4 close striking the upper band (≈80.30). This typically denotes strength but also overextension. Bandwidth has widened by 40% since May, signaling increased directional conviction. While prices hugging the upper band favor upside continuation, a mean-reversion move toward the 20-day SMA (≈73.50) remains plausible if volume fades. Sustained closes above the upper band are rare, suggesting a minor consolidation phase may precede further advances.
Volume-Price Relationship
Volume surged to 389,732 shares on June 4, more than double the 50-day average and significantly exceeding June 3’s 134,593. This validates the breakout, indicating institutional participation. Notably, the rally’s two-day volume profile (524,325 shares) dwarfs the preceding three sessions’ cumulative turnover (497,694), confirming accumulation. However, volume divergence emerged in late May when prices rose to 75.14 (May 30) on below-average volume, questioning sustainability. The current volume-backed surge appears more durable, but failure to maintain turnover >300,000 shares may weaken upward impetus.
Relative Strength Index
The 14-day RSI (≈78) entered overbought territory (>70) on June 4, reflecting extreme near-term bullishness. Historically, such levels preceded pullbacks in April and December 2024. Nonetheless, RSI can remain elevated in strong trends, and the absence of bearish divergence tempers reversal concerns. Probabilistically, while an RSI > 70 signals overheating, it does not preclude further gains if momentum persists. A dip below 70 would signal short-term cooling without invalidating the broader uptrend.
Fibonacci Retracement
Applying Fibonacci retracement to the swing low of 46.88 (April 8, 2025) and the June 4 high of 80.33 yields key levels: 38.2% (67.50), 50% (63.60), and 61.8% (59.70). The price has convincingly breached the 38.2% resistance (now support) during the June 2–4 rally. This level converges with the 100-day MA (≈60.80) and the Bollinger midline, creating a high-confidence support zone near 67.50–68.00. A pullback to this area would align with historical reactions to retracement supports and offer potential accumulation opportunities.
Confluence and Divergence Observations
Strong confluence exists between the 50-day MA, Fibonacci 38.2% level, and Bollinger midline near 67.50–68.00, solidifying this as critical support. Conversely, RSI and KDJ overbought signals diverge from MACD’s unwavering bullishness, hinting at short-term consolidation risk. Volume-backed price strength and moving average alignment favor bullish continuation, but indicator extremes and resistance at 80.33–80.50 suggest potential consolidation before further upside. A close above 80.50 on sustained volume could invalidate overbought concerns and target 83.00, whereas failure below 78.25 may test 75.14.
