Vertiv Holdings (VRTX) Surges 4.02% on Strong Technical Indicators Extends Three-Day Winning Streak to 10.96% Rally Near One-Year High

Vertiv Holdings (VRTX) has surged 4.02% in the most recent session, extending its winning streak to three consecutive days with a cumulative gain of 10.96%. This sharp rally reflects strong buying pressure, with the stock trading near its highest levels in the past year. The following analysis evaluates key technical indicators to assess the sustainability of this move and potential near-term scenarios.
Candlestick Theory

The recent price action forms a bullish continuation pattern, with higher highs and higher lows over the past three days. A key support level appears at the 155–159 range, where the stock found a floor after a significant selloff on December 17 (closing at 149.83). Resistance is currently at 166.25, the most recent closing high. A break above this level could target the 170–175 range, which acted as resistance in early December before the selloff. Conversely, a pullback to the 155–159 support zone may trigger a test of the 147–151 area, a prior swing low.

Moving Average Theory
Short-term momentum is confirmed by the 50-day (approximately 158–160) and 100-day (around 162–165) moving averages, both of which are sloping upward and currently below the 200-day MA (166–168). This “bullish crossover” suggests intermediate-term strength, though the 200-day MA may act as a dynamic resistance. If the stock closes above the 200-day MA, it could signal a shift in trend toward a longer-term uptrend. Conversely, a drop below the 50-day MA would indicate weakening momentum.
MACD & KDJ Indicators
The MACD histogram is expanding positively, with the line above the signal line, confirming bullish momentum. The KDJ oscillator shows %K (38.2–50% level) rising above %D, suggesting a potential continuation of the uptrend. However, the RSI (discussed below) and KDJ are nearing overbought territory, which may indicate a short-term correction is due. A divergence between price highs and KDJ highs would be a bearish warning, though this has not yet materialized.

Bollinger Bands
Volatility has expanded significantly, with the upper band currently at ~170 and the lower band at ~150. The stock is trading near the upper band, indicating a strong rally amid heightened volatility. A pullback to the middle band (~160) would test the 50-day MA and could stabilize the trend. A break below the lower band would signal a potential reversal, though this scenario seems unlikely given the current bullish setup.
Volume-Price Relationship
Trading volume has spiked during the recent rally, peaking at 11.96 million shares on December 17, the day of the selloff, and again at 5.69 million on the most recent session. This surge in volume validates the strength of the rally. However, a divergence between rising prices and declining volume in subsequent sessions could signal waning momentum. For now, volume supports the view that the uptrend is driven by genuine demand.
Relative Strength Index (RSI)
The RSI is approaching overbought levels (~68–70), suggesting a high probability of a near-term pullback. While this does not necessarily signal a reversal, it indicates the stock may consolidate or retrace before resuming higher. A drop below 50 would confirm weakening momentum, but as long as the RSI remains above 50 and aligns with positive MACD, the uptrend remains intact.
Fibonacci Retracement
Key Fibonacci levels from the December 17 low (147.82) to the December 10 high (181.82) include 23.6% (164), 38.2% (160), and 50% (164.8). The current price of ~166.25 is above these levels, indicating strong bullish momentum. A retest of the 160–164 range would provide a critical test of support. A breakdown below 160 would likely target the 155–159 zone, while a sustained move above 170 could challenge the 175–180 resistance cluster.
Conclusion
The confluence of bullish signals—rising moving averages, expanding MACD, and strong volume—supports the continuation of the uptrend. However, overbought RSI and proximity to Bollinger Bands suggest caution for short-term traders. Divergences to monitor include a potential RSI divergence or a volume contraction during further gains. For now, the probability favors a continuation of the rally, with key watchpoints at 160 (support) and 170 (resistance).
