Apple · AAPL
NASDAQ · Technology / Consumer Electronics / Ecosystem
Apple's moat isn't the iPhone itself — it's the user stickiness created by the entire ecosystem. Duan believes the iPhone may be the "cheapest phone" because users get far more value than they pay. The more he researches Apple, the more he likes it. He views it as a company that has truly achieved user focus, with extraordinarily high business model certainty.
Kweichow Moutai · 600519.SH
Shanghai Stock Exchange · Consumer / Baijiu / Cultural Commodity
Moutai sells not just liquor, but the ritual and status embedded in Chinese culture — a moat that is nearly impossible to replicate. Duan is bullish on the long-term consumer upgrade trend of "drink less, drink better," and views Moutai as one of the rare consumer brands with genuine pricing power.
NetEase · NTES
NASDAQ · Gaming / Internet
This is Duan's most classic "concentrated bet within the circle" case. In 2002 NetEase was on the verge of being delisted, with stock near $0.80, almost entirely abandoned by the market. Because Duan had spent years in the gaming industry, he deeply understood NetEase's business and was certain the market was drastically underestimating both the size of the gaming market and NetEase's competitive position. Buying gold at copper prices requires no courage.
PDD Holdings · PDD
NASDAQ · E-commerce / Consumer
Duan is the mentor of Huang Zheng (PDD's founder), and brought Huang to the 2006 Buffett lunch. He has a naturally deep understanding of PDD. But he has also repeatedly stressed that "knowing the founder" doesn't mean "you must own the stock" — real judgment still has to come back to the business model itself.
Bitcoin and Cryptocurrencies
Virtual Assets
Duan has consistently stated in Q&A that he won't touch Bitcoin, always for the same reason: he can't understand its business model or judge its future cash flows. "Never touch what you don't understand — this is an iron rule." He doesn't judge Bitcoin as good or bad — he simply says it's outside his circle of competence.
Business Model First, Price Second
Apple, Moutai, NetEase — every bet starts by confirming the business model is strong enough, then assessing whether the price is reasonable. The order cannot be reversed.
Concentrate Within the Circle
The NetEase case says it all: because he had spent years in gaming, he could stay clear-headed during peak market panic. Opportunities outside the circle? Pass.
Holding Period Measured in Decades
Every purchase starts with the question: "Am I willing to hold this company for ten years?" If not, don't buy. If yes, hold to that standard — don't be shaken by short-term moves.
Panic Is a Buy Signal, Not a Sell Signal
Moutai collapsed on anti-corruption fears. NetEase was suspended on an accounting scandal. To Duan, these were opportunities — as long as the fundamental business model hadn't changed.
Concentrate, Don't Diversify
Duan doesn't believe in "diversify to reduce risk." He thinks diversification is for things you don't understand. When you truly understand something, bet big.
Only Two Reasons to Sell
One: you discover your original judgment was wrong. Two: there's a better opportunity requiring capital reallocation. Stock went up or down? Neither is a reason.
