KLA Stock Rises 13.17% Weekly On Seven Day Bullish Streak

KLA (KLAC) shares concluded the most recent session at $856.59, advancing 3.29% and extending gains to seven consecutive days for a cumulative 13.17% weekly return. This persistent upward momentum frames the technical context.
Candlestick Theory
KLA exhibits a strong bullish sequence with seven consecutive white candles, culminating in a long-bodied candle on June 10 that closed near its high ($857.16) after testing intraday support at $826.76. This pattern signals robust buying pressure. Key resistance is now established at the June 10 high of $857.16, while former resistance near $800 (tested May 13–15) transitions to primary support. A bearish reversal pattern is absent, though extended gains increase susceptibility to profit-taking near the all-time high.
Moving Average Theory
The moving average configuration remains decisively bullish, with the 50-day MA ($781) maintaining above the 100-day ($758) and 200-day ($715) averages. The June 10 close at $856.59 positions the price 9.7% above the 50-day MA, demonstrating accelerated short-term momentum. The ascending order of these averages—50 > 100 > 200—confirms a sustained intermediate-to-long-term uptrend. The 200-day MA’s upward slope since January reinforces structural support.
MACD & KDJ Indicators
The MACD histogram shows expanding positive momentum, with the MACD line solidly above its signal line since May 30. Concurrently, the KDJ oscillator entered overbought territory (K-value >80) during the seven-day rally. While this alignment typically denotes strong trend continuation, the KDJ’s persistent overbought condition for seven sessions signals latent exhaustion risk. No bearish divergence is evident, but extended overbought readings warrant monitoring for momentum inflection.
Bollinger Bands
Bollinger Bands have expanded sharply during the rally, reflecting heightened volatility. Price has consistently traded near the upper band since June 3, suggesting strong directional conviction. The June 10 close touched the upper band ($858), coinciding with the session’s high. Historically, such prolonged upper-band proximity preceded minor consolidations, though no contraction (squeeze) currently implies immediate reversal risk is limited.
Volume-Price Relationship
Volume surged 11% above the 30-day average during the June 10 advance, confirming bullish conviction. This follows above-average volume on May 12 (8.45% rally) and April 9 (17.31% surge), establishing a pattern of volume validation for breakout moves. No volume divergence exists, as pullbacks (e.g., May 30’s 2.21% decline on elevated volume) lacked accumulation, supporting the uptrend’s integrity.
Relative Strength Index (RSI)
The 14-day RSI reads 75, nearing overbought territory (70+). While similar levels preceded minor consolidations in February and April, the RSI’s upward trajectory since the May 30 low of 39 indicates strengthening momentum. Given sustained trend strength, current levels may persist before triggering significant reversal signals.
Fibonacci Retracement
Applying Fibonacci to the March 31 low ($679.80) and June 10 high ($857.16) reveals confluent support at the 23.6% retracement ($805). This aligns with the prior resistance-turned-support zone near $800. The 38.2% level ($790) overlaps with the 50-day MA and May consolidation, offering robust secondary support. No retracement signals are active, but these levels present strategic entry points during pullbacks.
