Based on the perspective of the complex plane and Euler’s formula ($e^{i\theta }=\mathrm{コス}\theta +i罪\theta$), we can treat the current Hang Seng Index (HSI) not merely as a price chart, but as a dynamic system rotating through time. In this model, price fluctuations represent the conversion between “Phase” (market sentiment/timing) and “Energy” (capital flow/volatility).

Here is the deep tactical analysis of the current HSI macro cycle:

The HSI on the Complex Plane: Shifting from “Overheat” to “Equilibrium”

By mapping the current macro tactical cycle of the HSI (which bottomed at 14,794 in early 2024) onto the complex plane, we observe a profound rotation between “Expectation” and “Reality.”

1. Phase Analysis: Entering the “Profit-Taking” Second Quadrant

In this model, $90^{\circ }$ (approx. 28,056 points) represents the emotional peak of the cycle. With the HSI currently navigating the 25,000 range, the Euler Phase Angle sits at 146.2∘.

This indicates that the market has officially transitioned from the First Quadrant ($0^{\circ }-90^{\circ }$, the unilateral expansion phase driven by valuation recovery) into the 第2象限 ($90^{\circ }-180^{\circ }$). In physical terms, this is a stage of “kinetic energy dissipation.” Although the index remains above the median axis (approx. 21,425 points), the rotation vector has cleared the summit and is now in a tactical cooling-off period.

2. Radius Fluctuation: Geopolitics as “Centrifugal Force”

The radius $R$ in Euler’s formula represents the market’s volatility and total energy. The recent expansion of the radius is largely driven by external “centrifugal forces”—specifically the hawkish stance of the U.S. administration regarding Middle East tensions and the renewed tariff expectations on China-Hong Kong trade.

This force caused the market to dive toward the $180^{\circ }$ (Equilibrium) position with high instantaneous angular velocity shortly after approaching the 28,000 peak. This is not a collapse of fundamentals, but rather an “amplitude correction” on the complex plane to shed excess speculative heat.

3. Insight Drive: From “Valuation-Led” to “Earnings-Hardened”

• The Shift in Gravitational Pull: The rally from late 2024 to early 2025 was fueled by the denominator (improved interest rate expectations and Southbound fund inflows). As we hit $146.2^{\circ }$, the “rotational power” is switching. With earnings seasons progressing, the illusory “expectation premium” is being stripped away.
• Real vs. Imaginary Axis: On the complex plane, the Real Part ($\mathrm{コス}\theta$) represents the solidity of corporate fundamentals, while the Imaginary Part ($i罪\theta$) represents sentiment-driven premium. Currently, the Imaginary component is shrinking rapidly. The market is squeezing out the “water” left behind by both geopolitical panic and over-optimism.

Tactical Outlook: Seeking the 180∘ Anchor

Based on the current angular velocity, the HSI is gravitating toward the 180∘ Phase (the 21,400–22,000 zone), which acts as the “Mean Equilibrium Line.” This does not signal the end of the bull cycle, but rather a tactical homecoming.

Key Insight: Because the angular velocity is significantly higher during this downward arc than it was during the ascent, the market is exhibiting “fast crashes and slow climbs.” Investors should watch for the “Damping Effect” as the phase angle approaches $180^{\circ }$. Once the index settles near the median, and as domestic Chinese stimulus policies yield empirical data, the rotation vector is expected to accumulate new momentum in the lower quadrants for the next swing.

結論： We are currently in the “Post-Peak Cooling Phase”. The strategy should favor lower frequency trading, waiting for the phase angle to reach the $180^{\circ }$ equilibrium zone. This will be the strategic window to recalibrate the cycle radius and position for the next “upward rotation.”
