In this analysis, we map the Tactical Macro Cycle of the renewable energy industry onto the complex plane using Euler’s formula. By observing the phase shift of the rotating vector $e^{i\theta }$, we can more intuitively decode the market’s current momentum decay and its underlying structural support.

Complex Dynamics: Renewables and the Inertia of a Fading Peak

If we treat the macro cycle of the renewable energy sector as a rotating vector in a complex plane, then according to Euler’s formula ($V=R{e}^{i\theta }$), the industry is currently navigating a delicate inflection point. In our coordinate system, $90^{\circ }$ represents the absolute price peak, while $270^{\circ }$ marks the “darkest hour” or the cyclical trough.

1. Phase Angle 111∘: The “Tactical Condensation” After the Peak

Based on current market data (as of early April 2026), the global benchmark for renewables (ICLN) touched its $90^{\circ }$ phase peak ($19.38) on February 24, 2026, following a powerful year-long rally.

The current phase angle stands at 111∘. This indicates that the industry has crossed the threshold of overheating and has entered the 第2象限 of the complex plane.

From a physical perspective, as $\mathrm{コス}(111^{\circ })$ turns negative, the “Real Part” of the market—the absolute upward price momentum—is beginning to decelerate. However, $罪(111^{\circ })$ remains high (approx. $0.93$), suggesting that the “Imaginary Part”—market expectations, macro narratives, and fundamental sentiment—has not yet collapsed. This is a classic “high-level plateau,” where the market is digesting the valuation premiums accumulated over the past year.

2. Angular Velocity (ω): The Twin Engines of AI Power and Policy Tipping Points

This specific cycle began on April 9, 2025, when the phase was at $270^{\circ }$. The industry traveled from the depths of the trough to the peak in just 321 days, resulting in an angular velocity of roughly 0.56∘/Day.

This velocity, significantly higher than historical averages, is driven by two “Gravitational Pulls”:

• AI’s Thirst for Power: Between late 2025 and early 2026, the “compulsive” procurement of clean energy (via PPAs) by global data centers acted as a massive expansion force for the cycle’s Radius ($R$).
• The Energy Tipping Point: In mid-2026, global renewable generation officially surpassed coal. This historic “crossover” injected significant angular momentum into the vector, allowing the industry to maintain a wide rotation radius despite a high-interest-rate environment.

3. Expansion of Radius R: From “Policy Dependent” to “Structural Necessity”

In the complex plane, the radius $R$ represents the amplitude of the trend. Historically, the $R$ of the renewable sector was erratic, expanding and contracting based on government subsidies. However, the 2026 macro cycle shows a structural enlargement of $R$.

With $R$R currently holding at 4.46, the data suggests that renewables are no longer just a “thematic trade” for secondary markets; they have become the “hardcore infrastructure” of energy security and AI scaling. Even as we enter the $111^{\circ }$ corrective phase, the depth of the retracement is limited because the “cash flow base” has shifted from government handouts to corporate necessity.

Analyst Insight: Survival in the Second Quadrant

で $111^{\circ }$, we are looking toward $180^{\circ }$ (the point of mean reversion).

Tactical Advice: The industry vector is currently in a process of “converting kinetic energy into potential energy.” While prices have seen a technical correction of roughly $7$7 since the $90^{\circ }$ peak, this is not a cycle termination. Instead, the stability of the angular velocity between $111^{\circ }$ そして $180^{\circ }$ will depend on whether grid-side bottlenecks can be resolved.

まとめ： The renewable index is performing a “centripetal motion” in the high-valuation zone of the complex plane. 111∘ is a signal of sobriety: the peak has passed, but the inertia of the grand trend remains magnetic. Investors should avoid chasing the highs and instead wait for the vector to rotate into a zone of higher safety margin, leveraging this “tactical condensation” to re-anchor in high-$R$R assets within the AI-Power supply chain.
