What the method has learned, as opposed to what it has reported. Each note states one claim and declares how fast it goes stale.这里记录的是方法本身学到的经验,而不是它给出的报告。每一条只讲一个结论,并标明它多快会过时。

Market regime — the 2026 two-act rout
2026 ran two sequential, opposite routs — software crashed in March on AI-displacement fear while AI-capex names ran up, then AI-capex crashed in July — so "tech is down" is never a usable statement without naming which act and which layer.

"Down a lot" is not "cheap"
Measure valuation against a name's own historical multiple band, never against its 52-week high — a stock can be 40% off its high and still trade above every multiple it has ever sustained.
-
A P/E-multiple trim inverts on a peak-cycle cyclical
The watchlist's "Trim NNx fwd" convention computes its dollar level as NN x (price / forward P/E), so it scales with whatever EPS the market currently forecasts. On a compounder that is the point — the trim rises with earnings.
-
A REIT WACC has no interest tax shield, and CAPM inverts inside net-lease
Two standard WACC inputs break on REITs in the same direction — the after-tax cost of debt (a REIT pays no entity tax, so the interest deduction is worth nothing) and CAPM's cost of equity (net-lease betas rank inversely to…
-
A deferred-tax valuation allowance booked then released breaks two years of EPS
When a tax-law change forces a company to write a valuation allowance against its deferred tax assets and it later releases that allowance, GAAP net income takes a huge charge in one quarter and an equally huge credit in another.
-
A divested segment corrupts multi-year CAGRs, and the error always understates growth
When a company divests or discontinues a segment, vendor feeds restate the recent years to continuing operations but frequently leave the oldest years at the old total-company basis — so any CAGR computed across the boundary…
-
A stale entry zone silently suppresses the name it is attached to
An entry zone is a derivative of a fair value, so it goes stale exactly when the fair value does — and a zone left above the current price makes every scan report the name as "still below its add zone," which reads as not yet…
-
A written gate gets marked satisfied on management's adjective instead of its own arithmetic
When a prior analysis gates an upgrade on a falsifiable numeric test, the next earnings print arrives wrapped in management language that sounds like the test — "growth accelerated again", "momentum returned", "record backlog".
-
ADR feeds divide USD ADR price by ordinary-share book value, inflating P/B by the ADR ratio
On ADRs, vendor feeds frequently apply the ADR ratio to the price field but not to the book-value-per-share field, and separately fail to convert the local-currency book value to USD.
-
An issuer that terminates its ADR programme becomes fully analysable — verify, don't assume
The ADR data traps are properties of the depositary structure, not of foreign domicile.
-
Any figure carrying the verdict must come from the filing
Vendor feeds have been caught misreporting the exact figures that decide verdicts — FCF, margins, non-operating income — so any number the conclusion rests on gets pulled from the 10-K/10-Q or press release, not from a data feed.
-
Any sizing recommendation must read both account files, not just the default one
A single-stock analysis that reads only the default portfolio file will systematically under-weight every name concentrated in the second account, and can recommend HOLD on a position it believes is a few hundred dollars when it…
-
Buyback-manufactured EPS growth screens identically to operating growth, and the market pays the same multiple for both
A company with flat operating income and flat free cash flow can post double-digit EPS growth indefinitely by retiring shares, and no screener distinguishes that EPS from operating EPS.
-
Cabot (CBT) is not a semiconductor company
Cabot Corp's CMP slurry business left in 2000 and now sits inside Entegris — CBT today is ~63% carbon black for tires, so including it in a semiconductor-materials basket flatters the group's numbers with an unrelated business.
-
Conviction scoring fails on unused range, not on coarse increments — keep 0.5 steps and use the tails
Measured across 141 watchlist entries, the 0-10 conviction scale operates in practice as a 3.5-8.5 scale with 62% of names inside a 1.5-point band.
-
Dividend Yield Theory inverts into a buy signal exactly when the business is breaking
DYT compares current yield to a historical yield band, but the yield can only rise two ways — the dividend went up or the price went down — and DYT cannot tell them apart, so a collapsing price mechanically produces DYT's…
-
Dividend-adjusted close prices silently break historical multiple and yield bands
Yahoo's default close price is dividend-adjusted, so building a historical P/E, P/AFFO or P/B band from it understates every past multiple by the cumulative dividend yield — on a high-yield name this manufactures a false "it has…
-
ENTG FY2025 margins are wrong in both Yahoo and roic.ai
Entegris FY2025 margins are corrupted in Yahoo and roic.ai simultaneously — the widely quoted ~41% EBITDA margin is fiction, the true figure is 13–17% — proving that cross-validating two vendor feeds is not an independent check.
-
Every AI-levered field trades above its own historical multiple band
As of July 2026, every AI-adjacent field swept traded above its own historical multiple band despite large drawdowns, because the drawdown is smaller than the preceding run-up — so drawdown-driven screens in AI-adjacent sectors…
-
Flat margins during share loss mean the damage is ahead, not that the moat held
The standard moat test reads margin compression as moat erosion, so stable margins read as an intact moat. But an incumbent under attack chooses between ceding volume and cutting price, and only the second shows up in margin.
-
Foreign ADR tickers silently resolve to the wrong company
ADR ticker lookups return clean, plausible data for an entirely different company — SCRYY resolves to SCOR SE not Screen Holdings, CPCAY to Cathay Pacific not Capcom — so always confirm the returned company name before using any foreign-listing data.
-
Forward P/E higher than trailing P/E on a company guiding earnings down means the trailing base is fake
Forward P/E should sit below trailing P/E whenever earnings are expected to grow.
-
Government-warrant derivative liabilities make GAAP EPS a function of the share price
When a company issues warrants to a government or strategic investor and books them as a derivative liability rather than as equity, the mark-to-market runs through income — so the GAAP loss GROWS as the stock rises.
-
In a shortage, revenue growth and market-share loss coexist — check units, not dollars
During a supply shortage a company can post its fastest revenue growth in years while losing unit share in every segment, because price and mix carry the whole increase.
-
In a tech selloff, value is deepest in application software and shallowest in hardware
Across the March 2026 screen series the same ranking held at every pass — application software offered the deepest value, then cybersecurity and infrastructure software, with hardware consistently weakest on risk/reward — so…
-
Names repeatedly re-surfaced by screens that are no longer investable
Screening sources keep surfacing companies that have been acquired, taken private, delisted or wound down — check this list before researching any unfamiliar name, because the research is wasted and the "cheap valuation" is often a stale artifact.
-
Net margin above operating margin means the profit came from below the operating line
Net margin should always sit below operating margin — interest and tax subtract. When a screen shows net margin above operating margin, the excess did not come from the business.
-
Never discount a local-currency return at a USD cost of equity
A foreign company's reported ROE is denominated in its functional currency, not in USD — discounting a local-nominal return stream at a USD cost of equity credits the full nominal local return in the numerator while charging only…
-
Reject valuations that rest on TAM rather than revenue
A valuation supported by addressable-market size rather than realised revenue is a story, not a thesis — require the revenue line to exist and grow before any multiple is applied.
-
Script-data drug sales are gross of rebates and can be 45% above company-reported
IQVIA-style prescription data measures US drug sales at list price while the company reports net of rebates, so the two figures for the same product in the same year can differ by the entire gross-to-net spread — up to ~70% of…
-
Shortlists published into a fear-priced tape run 8-27% within two weeks — and have not been executed
Shortlists published into a fear-priced tape have run 8-27% within two weeks on all three occasions recorded (2026-07-14, 07-29, 08-04), so the analysis layer is reliable.
-
Simple FCF and company-adjusted FCF diverge by billions when JV partner funds move
For companies that co-fund assets with JV or SCIP-style partners, vendor "free cash flow" (operating cash flow minus capex) and the company's own "adjusted free cash flow" can differ by more than the entire capex line, because…
-
The AI build inflates reported earnings and destroys free cash flow at the same time
In 2026 the AI capital cycle shows up in financial statements as two simultaneous and opposite distortions: non-operating marks on private AI stakes INFLATE reported earnings, while capex or AI-delivery COGS DESTROY the free cash…
-
Unrealized equity-stake marks break the headline P/E on megacaps
Under ASU 2016-01 a company must mark its equity holdings to fair value through net income, so a large private stake that IPOs or revalues can inject tens or hundreds of billions of non-operating, non-cash income into GAAP…
-
Vendor "revenue" for banks is a net construct, not the reported top line
Yahoo and roic.ai report bank revenue as a net figure (roughly net interest income plus net fee income), which can understate the issuer's own reported total revenue by a third — making every vendor-derived P/S, revenue CAGR and…
-
Vendor feeds zero out deployment and inflate debt for sales-type-lease REITs
For REITs that book acquisitions as sales-type or financing-receivable lease investments rather than as business combinations, Yahoo and roic.ai report an acquisition line of exactly zero while billions are being deployed, and…
-
Vendor forward P/E silently uses the wrong fiscal year, and it flips verdicts
Yahoo's forwardPE/forwardEps does not state which fiscal year it estimates, and it is frequently neither the current year nor a consistent one across tickers — sometimes a year already three-quarters reported, sometimes a year out.
-
When a platform's ranking function sets monetization intensity, its KPIs are policy variables, not demand signals
If a platform's discovery algorithm can be tuned toward extraction, then its reported DAUs, hours and bookings measure the setting of that dial as much as they measure user demand — so a growth vintage produced by an…
-
Yahoo files strategic-investment marks under Interest Income
Yahoo Finance misclassifies mark-to-market gains on strategic equity stakes as "Interest Income", inflating apparent non-operating yield to impossible levels — sanity-check interest income against the cash balance.
-
Yahoo maps creator payouts and infrastructure into COGS, turning a contribution margin into a "gross margin"
For platform businesses that pay out to creators, Yahoo's grossMargins field nets content/creator payouts and infrastructure out of gross profit and labels the result a gross margin.
-
Yahoo mixes reporting currency and quote currency on cross-listed issuers
For an issuer that reports in one currency but trades in another (CAD-reporting, USD-listed), Yahoo converts the PER-SHARE fields to the quote currency but leaves the AGGREGATE income-statement fields in the reporting currency…
-
Yahoo's dividend yield uses previousClose while its P/E uses the live price
Yahoo Finance computes dividendYield and trailingAnnualDividendYield off previousClose, but computes trailingPE off currentPrice, inside the same payload.
-
Yahoo's insider_purchases field counts RSU grants and option conversions as "purchases"
Yahoo Finance's insiderpurchases summary reports RSU vesting at $0.00 and option conversions at legacy strikes as open-market "purchases" — on RBLX it showed "+3.5M net shares purchased, 12.3% buy" during a period with literally…
-
Yahoo's sharesOutstanding returns only the listed class on dual-class foreign issuers
For dual-class companies — especially foreign private issuers — Yahoo's sharesOutstanding field reports only the exchange-listed class, omitting unlisted super-voting shares; the same payload's marketCap silently uses the correct…
-
roic.ai FCF field returns OCF with capex null
Whenever roic.ai's cfcapexpenditures is null, it publishes cffreecashflow equal to cfcashfromoper — FCF with no capex subtracted — and silently propagates the error into freecashflowpersh and prtofreecashflow.

Automotive ADAS & sensing semiconductors
Swept 2026-06-12 over two rounds and 25 names as an INDI alternatives search — nothing cleared, and the pass also surfaced unresolved market-cap discrepancies between Yahoo and web sources on SITM, VICR and POWI.
-
BACEN systematically commoditizes each profitable layer of Brazilian banking
Brazil's central bank runs a consistent, repeated policy of building free public infrastructure that competes away the profit pool of each banking layer in turn — payments, then data, then interest rates, then installment credit…
-
BDCs & private-credit income
Swept twice (Apr and Jul 2026) against a deteriorating private-credit backdrop — BDC secondary sales fell 40% amid lengthening default shadows — so the field was screened on dividend coverage and NAV discipline rather than on yield.
-
Broad cross-sector value & global-vs-US screens
Broad "find value anywhere" screens have consistently underperformed field-specific ones in this repo — they surface names already covered elsewhere and, in the global case, produced an FX artifact mistaken for a discount.
-
Consulting, IT services & enterprise IT
Swept Jun and Jul 2026 — the useful distinction is revenue model, not sector: IT (Gartner) sells subscriptions and BAH sells government work, both uncorrelated to the project-based tech-spending cycle that drives ACN and CTSH.
-
Crypto-linked equities
Swept 2026-07-29 — since the user already holds BTC directly, coin-beta names are leverage on an existing position rather than diversification, so the only interesting question is which names have a real business independent of the coin price.
-
Fintech, payments & financial infrastructure
Swept 2026-03-21 for Visa-like asset-light toll-booth businesses — the field's quality is uniformly high so the binding constraint is price, not business selection, and in March only V and a handful of others were actually discounted.
-
GLP-1, obesity & metabolic pharma
Swept 2026-07-31 via NVO — the field is the largest therapeutic category in pharma history and is simultaneously the clearest case of a huge field with a losing incumbent: obesity volume compounds for decades while value per…
-
Gaming, adtech & consumer internet
Swept 2026-07-29 — NTES (conviction 7.0) survived as a non-AI-levered survivor, but it carries China structural risk, which is a different risk class from the valuation risk the sweep was screening for.
-
Hardware, networking, storage, components & electrical infrastructure
Swept across five March 2026 screens — consistently the weakest risk/reward layer in the tech selloff (narrower moats, softer FCF) with NTAP/CDW/ZBRA the only names of interest; never refreshed since, so the entire field is stale by four months.
-
Health tech & healthcare software
Swept 2026-07-29 and produced the best result of the entire July exercise — DOCS at conviction 7.0 and in its entry zone, because the field is not AI-narrative-levered and so did not participate in the run-up that left every adjacent field expensive.
-
Healthcare, energy, industrials/materials, staples & telecom
Swept 2026-07-29 as the "unswept fields" pass and rejected by the user on business-model grounds rather than valuation — the durable finding is that the 2026 defensive rotation bought the label, not the cash flow.
-
Japan tech & semiconductors
Swept 2026-07-29 and the premise failed — Japan's apparent discount was an FX artifact (EWJ −8.4% ≈ yen −8.41%, while TOPIX set a record close), and Japanese AI names carry zero discount, with Advantest at 60x P/E and 28x P/B.
-
Nuclear, uranium & the enrichment pipeline
Swept 2026-06-10 across the full fuel-cycle stack (mining → enrichment → SMR → generation) — the durable finding is that the layers carry completely different risk types, so "nuclear exposure" is meaningless without naming the layer.
-
Optical, photonics & datacom interconnect
Swept 2026-07-29, no entries — 10 of 13 names traded above their own historical bands (LITE at 2.6x its own recent-high P/B) and three of the field's familiar names are no longer independently investable.
-
Quantum computing
Swept 2026-04-28 (IONQ, RGTI, QBTS) — only QBTS cleared the bar for even a speculative position, and only on a 40-45% pullback, because it was the sole name with a demonstrable near-term business rather than a roadmap.
-
REITs — US & Canada
Swept twice (Apr and Jul 2026) on a discount-to-NAV/AFFO-durability basis, with the July run adding US net-lease and industrial names; AFFO coverage rather than headline yield was the operative filter throughout.
-
Robotics, automation, machine vision & physical AI
Swept 2026-07-29, no entries — the quality names (CGNX, ZBRA and peers) trade at 32-35x earnings despite the selloff, so the field is a watch-for-price list rather than a research problem.
-
Semiconductor equipment (WFE) & automated test (ATE)
Swept 2026-07-15 to 07-29, no entries — all 11 ATE names traded above their own historical multiple bands despite a −28.6% SOX drawdown, and the WFE names that matter are gated on August prints rather than on price.
-
Semiconductor materials, consumables & subsystems
Swept 2026-07-29, no gems — materials tracks fab UTILIZATION while equipment tracks fab CAPEX, so "materials is the defensive way to own semis" holds against capex cuts and inverts against utilization declines; in the July 2026…
-
Small-cap AI, defense, space, drones & precision industrials
Swept heavily in June 2026 (50+ names across four screens) and the field's own verdict was that it is "genuinely hard to screen right now" — quality is scarce, the graveyard of dead names is large, and story-over-revenue is the dominant failure mode.
-
Software & SaaS — all subsectors
The most heavily swept field in the repo (12+ screens, Mar–Jul 2026) — the March SaaSpocalypse produced genuine below-own-band value in application software, but no screen has ever been scored against outcomes, so the field's real lesson is still unread.
