In the Hong Kong and US markets, some trade on intuition, others surf on emotion. But Aaron_Hy belongs to a breed that commands respect even from peers: running a business by day, watching the market by night. With solid research and hyper-strong execution, he navigates the noise of high-volatility options and the tech sector time and time again.
He is not a gambler; he has professionalized "fast-paced short-term trading" to the extreme. Nor is he a typical value investor, yet every entry is backed by systematic deduction and data support.
Here, he candidly shares his combat methods, his most brilliant track record, and the moments that truly shifted his investment mindset.
I. The Other Side of the Entrepreneur: Investment Reinforced His Stress Tolerance and Discipline
Aaron_Hy has been an entrepreneur for years. He says starting a business and investing are not the same thing, but entrepreneurship made him more cautious and better able to handle pressure. He only entered the market systematically after earning his "first pot of gold" in 2017. Since then, he has participated deeply in Hong Kong and US stocks and options, trying almost every high-liquidity instrument available. Today, he still prefers the high efficiency of US stocks and options.
II. Style: A High-Execution Short-Term Player with Long-Term Logic at Heart
When describing his style, he summarizes it in one sentence:
"Aggressive, loves to operate, fast-paced."
His short-term system relies on four dimensions:
Moving Average Rhythm
Intraday Order Flow Structure (Bid/Ask)
Volume Changes
Event-Driven (e.g., Earnings, Macro catalysts)
Although a typical short-term player, he sees the market changing. As quantitative models increasingly dominate the board, pure short-term trading has become harder. Therefore, he has consciously increased his medium-to-long-term positions, using options more as an "enhancement tool" to amplify returns.
III. Powered by Quant Models: Stable 13-14% Annualized + Pre-Earnings Option Strategies
Talking about his model performance, he gives clear data:
Net Model Return: ~13-14% (after fees).
Strategy: Mostly buying options (Long Volatility).
Sweet Spot: Pre-earnings layouts have a significantly higher win rate in his experience.
He cites his most successful recent trade: Positioning into $CoreWeave, Inc.(CRWV)$ 100 Puts before earnings on August 12th, locking in massive profits early. For him, models are not metaphysics; they are discipline.
IV. The Two Stars of the Year: How He Caught $SanDisk Corp.(SNDK)$ & $Advanced Micro Devices(AMD)$ Early
His research method is extremely "boots on the ground":
Personally visiting computer markets and GPU rental markets to check orders.
Building his own PC to test product performance.
Observing the real market share shift of AMD's X3D structure CPUs.
Noting that high-performance memory cards in the compute market were in chronic shortage.
Consequently, he heavily positioned into SanDisk and AMD early, both yielding brilliant returns. He puts it bluntly:
"Those who double their money never do it by following the herd, but by continuous learning and research."
V. Stop-Loss & Options Logic: "Intraday" is the Best Risk Management
On risk control, he offers a minimalist but effective system:
Best Options Stop-Loss: Do not hold overnight; close out intraday.
Selection: Prioritize targets with extreme liquidity.
Comfort Zone: IV (Implied Volatility) around 50.
Extreme Scenarios: In high IV environments, he uses Straddles to hedge Vega risk.
No complex models—just the sedimentation of experience and discipline.
VI. Why Rarely Sell Options?
His answer is crystal clear:
"Selling has a high win rate but limited upside. I prefer opportunities with strong directionality where the risk is clear to me."
Therefore, he is a buyer almost all the time.
VII. Market Outlook: Is there a Christmas Rally?
His judgment focuses on structure rather than emotion:
Key Observation Point: Can the Nasdaq break new highs in November?
If it breaks through, the bull market may extend into December.
Currently, capital shows signs of profit-taking; we need confirmation of a re-established direction.
VIII. The First $100k — From Shorting $Tesla Motors(TSLA)$
His first $100,000 profit was "hardcore": 300,000 HKD → 1.2 Million HKD in just 10 trading days. Strategy: All-in on Tesla Put Options. Simple, brutal, but incredibly precise.
IX. The Road to a Million: Target 2026, Sprinting with Fans
He has achieved million-dollar returns in the past, but this time, he wants to complete it again using real trades on Tiger Brokers. Target Date: 2026. He says:
"It's both a challenge to myself and an answer to the fans who have been following me."
