Rolling a Snowball (Long Slope, Thick Snow)
Good company = Long slope × Thick snow—both essential
📌 Concept Explanation
Rolling a snowball = A company capable of sustained compound growth on a sufficiently long track backed by sufficiently thick competitive advantages.
Have you seen rolling a snowball? It gets bigger and bigger, requiring two conditions: the slope must be long enough (otherwise it stops when it reaches bottom), and the snow must be thick enough (otherwise it gets smaller as it rolls). Good companies are the same—the industry space must be big (long slope), the moat must be deep (thick snow). With only a long slope but no thick snow, the snowball won’t grow large; with only thick snow but no long slope, it won’t roll far.
💡 Core Understanding
1. “Long slope” doesn’t refer only to the industry but whether the company itself can go the distance.
Duan explicitly stated: “The ‘long slope’ here doesn’t just mean the industry—it includes whether the company itself can sustain the long run, so corporate culture is important.” An industry may have huge space, but if corporate culture has problems, it still can’t go far. The prerequisite for built to last is the company’s ability to keep running, not just standing on a large track.
2. “Thick snow” refers to the moat—the depth of competitive advantage.
Companies pursuing “price-performance ratio” often lack both long slopes and thick snow. Duan said: “Companies claiming to pursue ‘price-performance ratio’ are mostly making excuses for low pricing. Long-lived companies probably don’t emphasize ‘price-performance ratio’ much—people know quality when they see it. Good stuff isn’t cheap.” Low-price competition consumes snow rather than accumulating it.
3. Only companies with long slopes and thick snow deserve long-termism holding.
When Duan invested in Tencent, these four words captured his thinking: “Long slope, thick snow!” His judgment of Apple was similar—Apple sits on a long slope with thick snow. Such companies don’t need frequent trading; time itself is their friend. Conversely, companies with “short slopes and thin snow” won’t succeed no matter how hard you try.
4. Amazon is a special case: long slope but thin snow.
Duan said: “Amazon? Certainly a long slope, but the snow up there isn’t very thick—or how could they persist losing money for 20 years?” This shows long slope and thick snow are two independent dimensions that shouldn’t be confused. Long slope plus thick snow is the ideal combination; long slope without thick snow means the company needs continuous heavy investment just to maintain competitiveness.
🛠 How to Practice
To judge whether a company has “long slope and thick snow,” ask two questions:
- How long is the slope? Will this industry still exist in 10 years? How much market space remains? More importantly, can this company’s corporate culture and management support its continued running along this slope?
- How thick is the snow? What is this company’s moat? Brand, user stickiness, cost advantages, or network effects? Will this moat deepen over time or erode?
A reverse test: If a company mainly attracts users through “price-performance ratio” (low prices), it likely lacks both long slope and thick snow—low-price competition consumes moats rather than building them.
📖 Case Study
Moutai: A classic case of long slope and thick snow
Duan said: “Moutai certainly qualifies?! Long slope, thick snow, though occasionally losing a bit of snow.” Moutai’s “slope” is China’s long-term demand for high-end baijiu; its “snow” is brand moat and pricing power—both extremely difficult to replicate.

Tencent: The core judgment at purchase
In October 2018, Duan began building his position in Tencent. His judgment boiled down to four words: “Long slope, thick snow!” He also stated Tencent could probably earn 200-300 billion RMB annually within 10-15 years.

⚠️ Common Misconceptions
-
❌ “Big industry means long slope” — Correction: Duan said “The ‘long slope’ doesn’t just mean the industry—it includes whether the company itself can sustain the long run, so corporate culture is important.” Big industry but bad corporate culture still won’t go far. (Source: Business Logic Chapter, 2017-03-18)
-
❌ “High price-performance ratio companies have competitive advantages” — Correction: “Those pursuing ‘price-performance ratio’ probably have neither long slopes nor thick snow.” Low-price competition consumes moats rather than building them. (Source: Business Logic Chapter, 2017-03-17)

滚雪球（长长的坡，厚厚的雪）
好公司 = 长长的坡 × 厚厚的雪，缺一不可
📌 概念解析
滚雪球 = 一家公司能在足够长的赛道上，凭借足够厚的竞争优势，持续复利增长。
你见过滚雪球吗？雪球越滚越大，需要两个条件：坡要足够长（不然滚到底就停了），雪要足够厚（不然越滚越小）。好公司也一样——行业空间要大（长坡），护城河要深（厚雪）。只有长坡，没有厚雪，雪球滚不大；只有厚雪，没有长坡，雪球滚不远。
💡 核心理解
1. “长坡”指的不只是行业，更是企业本身能否长跑。
段永平明确说过：“这里长长的坡其实不光指的是行业，而是包括企业本身能否长跑，所以企业文化很重要。“一个行业空间很大，但企业文化有问题，照样跑不长。基业长青的前提，是企业有能力持续奔跑，而不只是站在一个大赛道上。
2. “厚雪”指的是护城河——竞争优势的厚度。
追求”性价比”的公司，往往既没有长长的坡，也没有厚厚的雪。段永平说：“说追求’性价比’的公司大多是在为自己的低价找借口。长寿公司大概是不太强调’性价比’这个概念的，老百姓心里有杆秤。好货不便宜啊。“低价竞争是在消耗雪，而不是在积累雪。
3. 长坡厚雪的公司，才值得长期主义持有。
段永平投资腾讯时说的就是这四个字：“长长的坡，厚厚的雪！“他对苹果的判断也是如此——苹果是在一个长长的坡上，雪也是厚厚的。这类公司不需要频繁操作，时间本身就是朋友。反过来，“短短的坡，雪也是少少的”公司，再怎么折腾也没用。
4. 亚马逊是一个特殊案例：长坡但雪不厚。
段永平说：“amazon？当然是长长的坡，但上面的雪不太厚啊，不然人家怎么能坚持亏 20 年？“这说明长坡和厚雪是两个独立维度，不能混为一谈。长坡厚雪才是最理想的组合，只有长坡没有厚雪，公司需要持续大量投入才能维持竞争力。
🛠 如何实践
判断一家公司是否”长坡厚雪”，问两个问题：
- 坡有多长？ 这个行业 10 年后还在吗？市场空间还有多大？更重要的是，这家公司的企业文化和管理层，能支撑它在这条坡上一直跑下去吗？
- 雪有多厚？ 这家公司的护城河是什么？是品牌、用户粘性、成本优势，还是网络效应？这个护城河会随时间加深，还是会被侵蚀？
一个反向检验： 如果一家公司主要靠”性价比”（低价）吸引用户，那它大概率既没有长坡也没有厚雪——低价竞争是在消耗护城河，而不是在建立护城河。
📖 案例拆解
茅台：长坡厚雪的典型
段永平说：“茅台当然是吧？！长长的坡，厚厚的雪，虽然偶尔会损失一点点雪。“茅台的”坡”是中国高端白酒的长期需求，“雪”是品牌护城河和定价权——这两者都极难被复制。

腾讯：买入时的核心判断
2018 年 10 月，段永平开始建仓腾讯，他的判断就是四个字：“长长的坡，厚厚的雪！“他同时说，腾讯大概率 10-15 年内一年可以赚 2000-3000 亿人民币。
