Vertiv Stock Rises 7.37% in Three Days as Technicals Signal Bullish Momentum

Vertiv Holdings (VRT) concluded the most recent session with a 3.80% gain at $134.23, marking its third consecutive daily advance and a 7.37% rise over this period. This upward momentum provides context for the following technical assessment.
Candlestick Theory
The current three-day rally forms a bullish "Three White Soldiers" pattern, characterized by consecutive higher closes with minimal lower wicks—particularly evident in the August 28 session, where the price held near the high of $134.93 after testing support at $131.17. This signals robust buying pressure. Key resistance is established at $135.78 (August 18 high), while the $131.17–$129.31 zone (August 27–28 lows) now acts as immediate support. A close above $135.78 would confirm bullish continuation potential.
Moving Average Theory
Vertiv trades well above its primary moving averages, with the 50-day MA at $125.42, 100-day MA at $118.73, and 200-day MA at $105.18. The ascending alignment of these MAs (50 > 100 > 200) confirms a sustained uptrend. Recent bounces off the 50-day MA in late July 2025 (supporting a rally from $120.72 to $134.23) demonstrate its reliability as dynamic support. Such configuration signals strong intermediate-term bullish momentum.
MACD & KDJ Indicators
The MACD (12,26,9) shows a bullish crossover since August 26, with the histogram expanding positively—indicating accelerating upward momentum. Meanwhile, KDJ registers overbought conditions (K: 88, D: 82, J: 100), typically warning of short-term exhaustion. While this divergence suggests potential consolidation, the MACD’s strength implies pullbacks may be limited. A bearish KDJ crossover would heighten near-term caution.
Bollinger Bands
Price currently hugs the upper Bollinger Band (20-day SMA: $129.45, upper band: $136.95), reflecting high volatility and bullish conviction. The bands expanded markedly during the August 26–28 advance, confirming breakout validity. Historically, such expansions precede momentum continuations; however, sustained trading at the upper band increases short-term mean-reversion risk toward the 20-day SMA.
Volume-Price Relationship
Volume surged 37% during the three-day rally (August 26–28 average: 6.39M shares vs. prior 10-day average: 5.62M), validating bullish momentum. Notably, the August 13 sell-off occurred on 9.98M shares—the second-highest volume of the year—suggesting distribution near $145. Current volume patterns lack such red flags, though weakening volume on further gains would question sustainability.
Relative Strength Index (RSI)
The 14-day RSI reads 72.4, entering overbought territory (>70). While this warns of consolidation, RSI divergence hasn't materialized; recent highs align with RSI peaks. In strong trends, RSI can remain elevated for extended periods. Traders should monitor for bearish divergence or a break below 70 to signal exhaustion.
Fibonacci Retracement
Using the December 2024 low of $75.20 and January 2025 high of $155.84, key levels emerge. The recent consolidation respected the 38.2% retracement ($111.52), while the current rally faces resistance at the 23.6% level ($135.62)—converging with the August 18 high. A decisive close above $135.62 opens a path toward the record high, whereas failure here could retest the 50% retracement at $104.94.
Confluence and Divergence
Confluence exists at $135–$136 (psychological resistance, Fibonacci 23.6%, prior swing high), making this a pivotal zone. Bullish alignment is evident in moving averages, MACD, and volume support. Key divergence appears in overbought KDJ and RSI readings against sustained price strength. Volume patterns lack the distribution signals observed at the 2025 peak, tilting probabilities toward upside resolution after consolidation.
