Pure Storage Surges 15.16% as Bullish Technical Signals Align, RSI Nears Overbought Threshold

Candlestick Theory
Pure Storage (PSTG) has exhibited a robust bullish momentum over the past five sessions, marked by higher highs and higher lows, forming a classic "bullish trend continuation" pattern. Key support levels are identified at the recent low of $83.15 (Nov 25) and $80.135 (Nov 25), while resistance is clustered around $88.96 (Nov 28), the most recent closing high. The candlestick bodies during this rally show elongated bullish closes, suggesting strong buying pressure. However, a potential bearish reversal could emerge if the price fails to hold above $85.77 (Nov 26), a prior psychological threshold.

Moving Average Theory
Short-term moving averages (50-day, 100-day) have crossed above the 200-day MA, signaling a bullish "golden cross" trend. The 50-day MA currently sits at ~$83.50, while the 200-day MA is near $78.50, indicating a medium-term uptrend. The 20-day MA (~$86.50) further reinforces the short-term bullish bias, aligning with recent price action. Divergence may arise if the 50-day MA flattens or dips below the 100-day MA, which could signal weakening momentum.

MACD & KDJ Indicators
The MACD histogram has shown positive divergence, with the line rising above the signal line since mid-November, confirming the uptrend. The KDJ stochastic oscillator, however, indicates overbought conditions, with %K at ~85 and %D at ~82, nearing the 80 threshold. This suggests a potential pullback or consolidation phase, though the RSI (discussed below) and MACD may delay a reversal if buying pressure persists.
Bollinger Bands
Bollinger Bands have widened significantly since late November, reflecting increased volatility during the 15.16% rally. The price has remained near the upper band for three consecutive sessions, a common precursor to mean reversion. A break below the 20-day MA (~$86.50) could trigger a contraction phase, tightening the bands and signaling reduced volatility.
Volume-Price Relationship
Trading volume has surged during the rally, peaking at ~4.49M shares on Nov 24 and ~3.3M on Nov 28, validating the strength of the upward move. However, the recent volume spike on Nov 28 (2.55M) is lower than the Nov 24 level, hinting at potential exhaustion. If volume declines further while the price remains above $85.77, it may indicate unsustainable momentum.
Relative Strength Index (RSI)
The 14-day RSI stands at ~72, entering overbought territory. While this does not guarantee a reversal, it suggests caution. A close below 60 would reduce overbought concerns, but a sustained move above 75 could prolong the uptrend. Historical data shows RSI often reverts to the mid-60s during consolidation phases, implying a probable correction unless the stock breaks out above $90.
Confluence and Divergences
Confluence is evident in the alignment of bullish moving averages, MACD, and volume, all supporting continuation. However, divergences exist between the overbought RSI and KDJ indicators and the MACD, which still trend upward. This suggests a high-probability scenario of consolidation or a sharp pullback if the 20-day MA fails. Traders should monitor the $85.77 level for a decisive break, which could trigger a shift in sentiment.
