2025 Investment Review: System Volatility, Nonlinear Growth, and Antifragility Experiments

Looking back at 2025, my biggest takeaway is this: being “in the know” can sometimes act as a cognitive lightning rod, and other times as a stumbling block to monetization.

As a full-stack engineer deeply involved in AI projects, I thought I could see through all industry bubbles. But ironically, the few core AI tickers that surged the most in 2025 were precisely the ones I, as an “insider,” had prematurely removed from my watchlist due to technical flaws.

I. A-Share Market Dynamics: When Consensus Meets “Kernel Overflow”

The A-share market in 2025 was a classic high-entropy game.

As I wrote in Fighting Entropy, systems always tend toward disorder. China’s A-share market in 2025 illustrated that perfectly. Again and again, fundamental analysis suffered a severe “kernel overflow” in the face of sentiment. I held companies with hard assets and stable cash flow while watching concept stocks dance wildly with algorithms fanning the flames.

The monitoring window in the bottom-right corner of my screen flashes red, looking exactly like my anxious ECG right now.

This experience forced me to recalibrate my mental models: in the A-share market, you do not just audit financial statements; you also audit the system’s “permission allocation.” I learned to preserve a 5% black-swan bet amid the frenzy, a tangible hedge against systemic uncertainty.

II. US Stock Premium: Capturing the Era’s Productivity

Compared to the disorder of the A-shares, the US stock market demonstrated strong logical continuity in 2025.

My mechanical keyboard sounds especially harsh late at night; every click seems to calculate the lifespan I’m losing.

I used my own AI Financial Report Assistant to continuously audit the Nasdaq’s core constituents. The evidence showed that the real premium still flows to giants that control foundational infrastructure such as the MCP protocol and can commercialize it.

Surviving in the cracks of the US stock market relied on my relentless focus on the principle of “marginal cost approaching zero.” If you can understand the distribution logic of a software product, you’ll see the power of compounding behind the fluctuating candlestick charts.

III.

The hardest lesson 2025 taught me is: never store all your assets in the same system.

I chug a mouthful of cold black coffee, the bitter liquid jolting my exhausted nerves.

Just as a NAS private cloud requires synchronization across multiple machines, investing needs physical separation across markets. I am turning the hard-won lessons of 2025 into my 2026 barbell strategy.

My Garmin watch vibrates with a sedentary reminder, but I can’t tear my eyes away from the error messages on the screen.

Stack assets at the foundation, view the world from above. 2025 is history; those traces of survival in the cracks will ultimately become the cornerstone for the next wave of compounding explosions.

The air is thick with the stench of garbage left out for three days—perhaps this is the price of hardcore real-world combat.

Let’s Talk

Honestly, these details about wealth management or outdoor life can only truly be felt through hands-on experience. I’m usually around Guanshanhu Park in Guiyang, where I often see people elbowing each other over a supermarket coupon, only to turn around and park hundreds of thousands into a product whose returns don’t even beat inflation. If you have thoughts on the points in this article, or if you’d like to meet up sometime in Guiyang for a coffee at the Guanshanhu Park Wetland, let’s chat in person.

The dim fluorescent tube above flickers twice, as if mocking my pointless persistence.

Wealth Growth Scenarios

Often, wealth management models sound like gibberish. But in my hands-on experience, these theories only make sense when applied to actual account operations. Here are the real-world scenarios I’m running alongside a few friends in the industry:

1. Hybrid Appreciation Under the Barbell Strategy

Allocate 80% of capital to extremely safe government bonds or dividend ETFs, and use the remaining 20% to gamble on highly volatile tech tracks, achieving growth with a guaranteed floor and unlimited upside.

2. Self-Sustaining Passive Income Systems

Optimize your asset structure by shifting inefficient dead money into high-dividend/yield targets, allowing the monthly cash flow generated by your portfolio to cover your car or mortgage payments.
