Margin of Safety Dashboard

What this is

Follow great investors, then wait for your own review zone

Demo
PurposeResearch
Tracked ideas0
Triggered0
Advice givenNone

The dashboard tracks public holdings, valuation ranges, and user-defined review prices. It does not tell users to buy or sell.

Core workflow

From idea to review alert

Framework
FindCollect companies from Berkshire filings, Morningstar, investor letters, and your own research.
ValueCompare current price, fair value, and a user-defined margin-of-safety price.
ReviewWhen price enters the review zone, generate a research memo instead of an automatic trade.
TrackUse paper portfolios and watchlists before any real-world decision.

Investment principles

Owner mindset before price action

Core rules
1Buying a stock means buying a business.

Do not study the ticker first. Study how the company makes money, why customers pay, what can go wrong, and whether it is inside your circle of competence.

2Good companies still need a margin of safety.

The value of a business is the present value of future owner cash flows. A great company can still be a poor investment if the purchase price leaves no room for error.

3If you would not hold it for 10 years, do not buy it.

Long holding periods let business quality, reinvestment, and compounding do the heavy lifting. The goal is not activity; the goal is durable ownership.

4Never risk permanent capital loss.

Compounding is powerful, but losses are brutal. Avoiding permanent loss matters more than chasing every extra point of return.

Compounding example

$10,000 held for 10 years

The longer the runway, the larger the compounding gap.

When the Buffett Indicator is elevated

Be selective
Do not panic-sellA high market-cap-to-GDP ratio is a temperature gauge, not a precise sell signal.
Do not chaseAvoid deploying all new capital into broad indexes or popular compounders at stretched prices.
Let cash earnUse cash, T-bills, term deposits, or short-duration bonds as paid patience.
Raise the hurdleDemand wider safety margins, stronger balance sheets, and clearer owner-earnings durability.
Defensive bucket35%-45%Cash, T-bills, term deposits, short-duration bonds.
Core bucket25%-35%Broad index exposure, deployed gradually over 6-12 months.

MoatWideThe durability of the company's competitive advantage.
StatusWatchThe dashboard label based on price versus value. It is a research signal, not a buy or sell instruction.
Important: premium-priced ideas do not have a margin of safety. Premium rows are marked as not available at a premium.
How fair value is estimatedFair value is a research estimate, not a market quote. It can come from discounted future cash flows, owner earnings, sum-of-the-parts, asset value, or a conservative normalized earnings multiple.
How review price is calculatedReview price applies a required margin to fair value. Example: fair value $100 and required margin 30% gives a review price of $70.
Why methods differCompounders may use owner earnings. Banks need book value and float quality. Cyclicals need normalized earnings or asset-cycle analysis.

Fair value (P/EV 0.9x)¥68

EV already uses conservative actuarial assumptions. P/EV 0.65x = 35% discount to fair value before any Graham MOS is applied. min(V₁, V₂) = ¥68.

③ Munger quality overlay
  • Moat expanding — NBV recovering, agency quality improving
  • Capital-light — ¥3.8T float compounds without reinvestment
  • Management hold shares — no large insider selling
  • No value destruction — property losses are cyclical, not strategic
All 4 Munger criteria met → 70% overlay applicable. However, current price already sits below the 50% Graham line at every growth scenario. No need to relax.

V₂ (DCF est.)¥64–74

DCF is stricter — H share above the pure DCF 50% line. Munger overlay bridges the gap. CF quality is high: operating CF ¥120.55B > net profit ¥93.12B.

③ Munger quality overlay
  • Moat expanding — global share 38% (+1pct), gross margin 37.27% (3-yr rising trend)
  • Capital-light — ROE 25.6%, vertical integration lowers unit cost
  • Founder holds majority — Cao family controls company
  • Succession risk — Cao Dewang is 78, no clear heir named
H share rose from HK$48 → HK$60.45 since July 9 analysis. Now above all buy lines. Munger 70% entry (¥44.8) requires ~HK$49. Wait for pullback — do not chase.

¥1,500B cash = ¥25.4/share (64% of stock price). Stripping cash out, the operating business trades at 3.5x P/E. 50% MOS on ¥73.4 = ¥36.7 — current ¥42 sits above that line.

③ Munger quality overlay
  • Moat intact — world's largest AC maker, compressor vertical integration
  • ROE 30% — world-class for manufacturing, limited reinvestment needed
  • Dong Mingzhu holds shares — skin in the game
  • Value destruction history — phones, chips, agriculture: repeated failed diversification
4th Munger criterion fails. Stay at strict 50% MOS. Operating business is extremely cheap at 3.5x P/E but the ¥1,500B cash is management's "experiment fund" risk. Hold, await better price or dividend commitment.

DCF intrinsic value ≈ ¥22–26: current price is at the upper edge of intrinsic value. Munger 70% at g=8% gives ¥28.8 → current ¥24.85 is inside that threshold.

③ Munger quality overlay
  • Moat — #1 brand in China but Mengniu is a near-equal rival; not a true monopoly
  • Capital intensity — cold-chain capex ~¥40B/yr; ROE 26% good but not exceptional
  • Management holds shares — clean record, no large selling
  • No value destruction — stable dividends, no failed diversification
2 criteria fully pass, 2 borderline. In Munger 70% zone at g=8%. Approaching but not yet at Graham 50% zone (need g=10–11%). Accumulate on dips below ¥24.

Graham 25/75 rule: bond ballast ensures stock allocation never exceeds 75%. SGOV sets the opportunity cost benchmark — any stock must deliver expected returns meaningfully above 4.4% to justify equity risk (target: 10%+).

No Graham formula needed
  • Ballast — floors portfolio against equity drawdowns
  • Ammunition — converts to stock positions when review zones trigger
  • Benchmark — every equity idea must beat this yield to be worth the risk
  • Rate risk — if Fed cuts aggressively, yield drops; consider laddering into 2–3yr Treasuries
Maintain as 20–25% of portfolio per Graham 25/75 discipline. Do not reduce below 25% regardless of market sentiment.

买供应链,不买整车 — Levi's 法则

Research theme
核心逻辑 淘金热不买矿工,买卖铲子的人。中国汽车出口2024年约550万辆,全球第一。10年后保守估计出口800万辆+,海外本地生产再加500万辆。供应商跟着整车走,受益无需押注哪家OEM胜出。
BYD 的顾虑 BYD净利润率仅~4%(电池+整车+地产),垂直整合压缩回报。海外扩张资本开支大,估值已定价乐观预期。整车选手竞争激烈,价格战侵蚀利润。
正确姿势 福耀(3606.HK)是最优供应链赌注,但当前HK$60已离开买入区间(7月初HK$48才进Munger 70%线)。等回调至HK$49–52。拓普、伯特利、敏实同样等MOS。CATL护城河真实但需跌至¥150。

China AI infrastructure sleeve

Low-cost tokens need power, compute, networks, and platforms

Research theme
Portfolio originThis research sleeve starts from the idea that low-cost tokens need a full infrastructure stack: power, chips, networks, cloud, and AI platforms.
Why we track itIf token costs keep falling, AI demand can migrate toward infrastructure that delivers the lowest cost per useful task.
Main riskPolicy risk, sanctions, capital controls, accounting quality, and price wars require a wider margin of safety.

物理AI · Physical AI

Robots, automation, sensing, and autonomous systems

Next decade theme
Why physical AI is differentSoftware AI runs in the cloud. Physical AI must sense the real world, reason at the edge, and act through motors and actuators. That adds cost, latency, and hardware dependencies that create durable moats — and durable investment themes.
Who wins the physical layerCompanies with durable installed bases, proprietary sensing and vision platforms, and edge AI compute are the picks-and-shovels of the physical AI era. NVDA's Jetson/Isaac stack, Keyence's direct-sales sensor model, and ISRG's razor-and-blade robot moat are structural advantages, not cyclical tailwinds.
Key risksHumanoid robots are still early-stage; capex cycles drive short-term revenue swings; NVDA and TSLA already price in significant optionality. Demand a wider margin of safety on speculative names and concentrate on proven industrial compounders first.
