Seagate Technology Surges 17.01% on Six-Day Winning Streak as Golden Cross and Strong Volume Fuel Bullish Momentum

Seagate Technology (STX) has surged 3.66% in the most recent session, marking a six-day winning streak with a cumulative gain of 17.01%. The price action suggests a strong bullish momentum, with recent highs reaching $229.33 and key support levels identifiable at $195.99 and $193.04. Candlestick patterns indicate a potential continuation of the upward trend, though traders should monitor for bearish reversal signals at critical resistance levels.

Moving Average Theory

The 50-day, 100-day, and 200-day moving averages align to confirm a positive trend. The 50-day MA is positioned above the 200-day MA, a classic "golden cross" configuration, reinforcing the bullish bias. The 100-day MA acts as a dynamic support line, currently around $210–$215, which has been tested and held in recent sessions. A break above $229.33 could trigger further upward movement, but a pullback below the 100-day MA might signal a short-term consolidation phase.

MACD & KDJ Indicators

The MACD histogram has shown expanding positive divergence, aligning with the recent price surge, while the signal line remains above zero, indicating sustained momentum. The KDJ (Stochastic) oscillator, however, suggests overbought conditions, with the %K line approaching 80. This raises caution about a near-term pullback, particularly if the %D line fails to confirm the %K’s peak. Divergence between price and the KDJ could foreshadow a reversal, though the overall uptrend remains intact.

Bollinger Bands

The price has recently touched the upper Bollinger Band, a sign of heightened volatility and strong trend participation. The bands have been widening since late August, reflecting increased trading activity. A sustained break above the upper band would suggest continued bullish momentum, while a contraction in band width could signal a period of consolidation. The lower band, currently around $190–$195, remains a critical support zone.

Volume-Price Relationship

Trading volume has surged during the recent rally, with the most recent session’s volume (5.24 million shares) being notably higher than the 40-day average. This validates the strength of the uptrend. However, if volume begins to wane while the price continues to rise, it could indicate weakening conviction among buyers. Conversely, a sharp increase in volume during a pullback would suggest strong accumulation at lower levels.

Relative Strength Index (RSI)

The RSI has entered overbought territory (>70), a common occurrence during extended rallies. While this does not necessarily signal an immediate reversal, it highlights the need for caution. A close below 60 would reduce the overbought warning, but a failure to break above prior resistance (e.g., $230.82) might lead to a retest of key support levels. The RSI’s divergence from price action in late August provides a cautionary precedent for potential corrections.

Fibonacci Retracement

Key Fibonacci levels derived from the recent high ($229.33) and a significant low ($193.04) include 38.2% at $213.36 and 61.8% at $207.18. These levels may act as temporary support zones during a pullback. A breakdown below $207.18 could target the 78.6% retracement at $196.35, which coincides with prior support levels.

Backtest Hypothesis

The backtest strategy of buying Seagate Technology when RSI indicates overbought conditions (e.g., >70) and exiting upon a drop below this threshold yielded a 10.5% average annual return from 2022 to 2025, underperforming the S&P 500’s 14.3% gain. This suggests the strategy’s conservative exit rules may have limited exposure to broader market rallies. A refined approach might involve holding positions through overbought RSI conditions if confluence with moving averages and volume confirms trend strength, while using Fibonacci levels to manage risk during pullbacks.
