Investing Insights
In-depth guides on factor investing, stock screening, and portfolio construction, grounded in academic research and written for serious investors.
It's in the Little Things
Accurate data is the foundation every decision stands on. A buyback champion docked for having negative equity. An $82M insider sale that read as -$500M. A 0.1% dividend yield that was really 6%. The unglamorous cross-checks that catch them, one stubborn detail at a time.
Qualcomm (QCOM): The $200B Chip Designer the Market Wrote Off Twice, and the Power-Limited AI Reframe
The market has written Qualcomm off twice: as an AI loser to Nvidia, and as Apple's soon-to-be-ex modem supplier. Both price it as a shrinking handset chip company. We unpack the reframe: a $200B designer diversifying into cars, PCs, glasses, and AI data centers, on the insight that AI compute is now capped by power, not chips. The 70%-margin patent moat, the Snapdragon platform, the Oryon and HBC hyperscaler deals, 20 years of dividend growth plus a fresh $20B buyback. Q78 V57 M58, StockRank 94.
The Hongkong and Shanghai Hotels (0045.HK): The Peninsula Owner at an 80% Discount to Assets, and the Value-Trap Question
HSH owns The Peninsula hotels, the Peak Tram, and the Repulse Bay estate, yet its $1.1B market cap sits ~80% below a $5.5B sum-of-the-parts. So why has the discount lasted a decade? We unpack the trophy assets, the Kadoorie family's 72.4% grip (they paid HK$12.8 vs HK$5.3 today), why a 0.9% ROE means the framework holds despite the NAV gap, and the ex-LVMH CEO's asset-light pivot as the one plausible catalyst. Q34 V46 M47, StockRank 36.
Aquawalk (0380.KL): Penguin Capitalism and the Toll-Bridge Economics of a $79M Malaysian Aquarium Operator
Aquawalk is Malaysia's Aquaria operator, a $79M company down 44% since IPO with half its market cap in cash. The operating business trades near 5x earnings. We unpack the toll-bridge economics (1.3M visitors, 59% gross margin, every extra visitor near-pure profit), the Process-Power-plus-location moat, why importing penguins is a pricing lever, and the Foong family buying at the lows. Q73 V75 M22, StockRank 82.
Congress Trades: What Politicians Buy, and Whether Copying Them Works
We now track every stock trade US Senators and Representatives disclose under the STOCK Act. But does copying them work? One study found a 1990s Senate edge of ~10% a year; another found Congress actually trailed the market. The law, the mixed evidence, and the feed.
Riverstone (AP4.SI): The Singapore Glove Maker Quietly Geared to the AI Boom Through Hard-Disk Cleanrooms
A $1B Singapore glove maker with a hidden AI angle: its priciest cleanroom gloves build the hard drives that store AI's data. Roughly 30% of volume but 70% of profit, a 30-year switching-cost moat over Seagate and WD, and a 6.5% dividend funded by net cash.
Micro-Mechanics (5DD.SI): A $338M Singapore Semiconductor Razor-Blades Compounder Up 3,000% Since 2003
A $338M Singapore maker of the tools that grip a silicon die smaller than a grain of rice, thousands of times an hour. Up 3,000% since its 2003 IPO. Razor-blade economics, a 40-year process moat, and one question: is 25x earnings fair for quality this rare?
Xiaomi (1810.HK): A $78B Profitable Phones-Cars-AI Conglomerate Down 57%, While a Pre-Revenue AI Lab Trades at $128B
A $78B conglomerate making phones, EVs, chips and an open AI model, down 57% from its peak. A 76%-margin services engine, an EV arm back in the red, real buybacks undone by dilution, and a StockRank 36 Hold where momentum is the whole problem.
Six New Markets: Austria, Ireland, Portugal, Greece, New Zealand, and South Africa Join the Ranked Universe
MoatMap now screens six markets it didn't before, taking coverage to 30 markets and 20,000+ equities. A quick tour of each: AT&S in Vienna, Ryanair in Dublin, the recovered Greek banks, Mainfreight in New Zealand, the JSE miners, and where to follow the flow.
AT&S (ATS.VI): The Only European Building Leading-Edge AI Chip Substrates, Up 11x as Customers Fund the Next Three Factories
The Vienna-listed AI chip-substrate maker that went from $0.8B to $8.8B in a year, the only European in a five-firm oligopoly. AMD and a second giant just signed long-term deals funding two new Malaysian plants. Capex tripled, guidance lifted, insiders called the bottom.
Greentown Management (9979.HK): The Marriott of Chinese Property at 6.3x Earnings With Zero Debt
The asset-light management arm of one of China's most respected housing brands: zero debt, 26% ROIC, 6.3x earnings, a 9.1% yield at full payout. Down 77% from its peak. A Marriott-style brand moat, and the bear case that the fees track a shrinking market.
The Double Signal: When a Company and Its Directors Buy the Stock at the Same Time
We scanned 60 days of filings across 14 markets for companies buying back stock while their directors bought too. Two Malaysian names pass clean; two famous ones, PayPoint and GSK, dissolve into share-plan noise the moment you read the filing. The screen and the traps.
Cluster Insider Buying: How to Tell Real Conviction from Share-Plan Noise
Four Nordic companies showed 8+ insider buyers in 60 days. Three are payroll: thirteen Skanska insiders all paying 255.580857 kronor isn't conviction. The one that's real, Bilia, where the chairman spent SEK 25.5M, averaging up each time. Three tests to tell them apart.
Perfect Attendance: The Companies Buying Their Own Shares Every Single Trading Day
Four London-listed companies bought their own shares on all 46 trading days of a ten-week window. Trainline's broker spends almost exactly £1,000,000 a day. What a never-miss-a-day buyback tells you, and the one thing it can't: whether the stock is actually cheap.
The Malaysia Value Up Guidebook: Why Japan and Korea's Trillion-Dollar Experiment Just Came to Bursa
Malaysia just copied the playbook that took Japan's Nikkei from 28,000 past 60,000 and doubled Korea's Value-Up index. What Tokyo and Seoul actually did, what Bursa is now asking its 88 largest issuers to do, and what it could mean for the Malaysian compounders we cover.
Chaoju Eye Care (2219.HK): A $230M Chinese Eye-Hospital Chain at 1.6x EV/EBITDA Where Cash Almost Equals the Market Cap
A Hong Kong-listed chain of 31 Chinese eye hospitals, down 76% since IPO, sitting on cash that nearly equals its market cap. A 9.5% yield at 1.6x EV/EBITDA. One patient, three transactions across a lifetime. Fortress balance sheet, or capital-allocation paralysis?
CTOS Digital (5301.KL): A 70%-Share Malaysian Credit Bureau Down 35% and the Cross-Border Question
Malaysia's dominant credit bureau: 70% share, wired into 600+ institutions, down 35% in a year. A cornered-resource-plus-switching-cost moat, a BNPL-law tailwind, a 2026 tax-break expiry, insider buying from the CFO, and the honest cross-border growth question.
Thai Beverage (Y92.SI): A $8.9B SE Asian Drinks Empire Where Value Carries StockRank 95 and the Moat Guards a Shrinking Pond
The $8.9B group behind Chang Beer, SangSom, SABECO and a 69.6% F&N stake: 80%+ Thai spirits share, 600k points of sale, a 5.5% yield held flat through three hard years. Value carries StockRank 95, but the moat guards a shrinking pond.
Farm Fresh (5306.KL): A Malaysian Milk Empire I Love as a Customer and the Framework Calls a Strong Sell
The Malaysian milk brand that took the chilled shelf from 12% to 51% share in a decade, on a 1,200 rural-women network multinationals can't copy. I buy it every week, and the framework calls StockRank 16, Strong Sell. That tension is the whole story.

Kimly (1D0.SI): A Singapore Kopitiam Empire Built on a Moat That Was Zoned Shut in 1998
A $399M Singapore operator of 89 HDB coffee shops at 97.5% occupancy, on a moat the government zoned shut in 1998. Three revenue streams per outlet, freehold conversions, and the honest question of paying 14x earnings for a no-growth, Singapore-only business.
Azeus Systems (BBW.SI): A Hong Kong Trust-Infrastructure Compounder With a StockRank of 99
The $271M Singapore software firm behind Convene, the board portal used by Fortune 500 directors and central banks. 21% revenue CAGR, 69% ROE, an 8.2% yield at 99% payout, StockRank 99. A certification moat, a 99% renewal rate, and a looming FY2028 contract cliff.

A $2.8B memory company shipping the only production-ready fix for the AI inference memory wall. A KV-cache server, 31% gross margins against Supermicro's 10%, AMD's CTO on the board, and a StockRank 87 profile up 90% in 30 days.
Fast Retailing (9983.T): Uniqlo Isn't Fashion. It's Infrastructure. And the Question Nobody Wants to Ask.
The $22B parent of Uniqlo, the world's third-largest apparel retailer and, really, infrastructure. HEATTECH process power, a closed loop with 39M annual feedback signals, a US runway from 76 to 200 stores, and one question: can the system outlive its 76-year-old founder?
Samyang Foods (003230.KS): How One Buldak Pack Turned Korea's Perpetual #2 Into a $6.7B Identity Brand
Korea's perpetual #2 noodle maker for 50 years, until Buldak went global on TikTok and it out-earned Nongshim on half the revenue. A capsaicin-sauce moat, new plants in Miryang and Jiaxing, +215% Europe sales. Coca-Cola staying power, or a passing wave?
Morningstar (MORN): When Founders Turn Aggressive on Buybacks, We Sit Up and Listen
A $6.2B research compounder that retired ~10% of its float in a year after barely buying back in 2023-24. When founders turn aggressive on buybacks, we listen. A five-engine data spine, a PitchBook re-rating read-through, and the AI questions that set the multiple.
Public Bank (1295.KL): 56 Years at 17.7% Per Year, Built One Toilet Roll at a Time
Malaysia's $22.9B third-largest bank compounded at 17.7% a year for 56 years, built by a founder who personally counted every toilet roll. The cost-discipline gap over DBS and JPM, the insurance pipeline, the ASEAN tailwind, and where you find the next one.

The $1.1B Hong Kong router maker behind Starlink's first Authorized Technology Provider status. A link-bonding moat, a 60,000-strong certified-installer community, an edge-computing pivot, a 2026 Nasdaq spinoff, and a StockRank 84 run on 200 staff and 68% founder ownership.
Linde (LIN): A $232B Industrial Gas Utility Wearing a Chemicals Costume
The invisible supplier to TSMC's Arizona fabs, America's blast furnaces, and four of every five SpaceX launches. 15-20 year take-or-pay contracts, a $10B backlog, 33 straight years of dividend hikes. A real compounder, or a financially engineered utility?
QL Resources (7084.KL): From Seashells in 1977 to a $3.4B Malaysian Protein Platform
It started in 1977 when a math lecturer sold calcium-rich seashells as chicken feed. Today it's a $3.4B platform making 1.5 billion protein servings a year. A waste-stream-as-next-business model, a FamilyMart halal edge, and 49 years of founder obsession.
Thakral (AWI.SI): A Singapore Conglomerate Trading at 37% of Sum-of-Parts, With a StockRank of 99
A S$192M Singapore conglomerate whose 16.8% GemLife stake alone is worth S$244M. Three businesses pretending to be one, DJI and L'Oreal distribution moats, and a sum-of-parts of S$5.32 against a S$1.95 quote. StockRank 99, a 63% discount.

A $51.7B Southeast Asia and Brazil compounder on a three-leg flywheel: Garena funds Shopee, which now underwrites Monee fintech. Down 56%, loan book up 80%, ads up 70%. StockRank 21, and why the market may be reading the wrong chapter.
Games Workshop (GAW.L): A 12-Year, 30-Bagger Hold, and What I Missed When I Bought It

Grab (GRAB): A Brilliant Southeast Asian Superapp, and Why It's a No From Me
A $15B superapp serving 52M monthly users across eight countries: 17 straight quarters of EBITDA growth, a $1.5B target, $1B in buybacks. A mobility cash engine, a fintech breakeven catalyst, a 10x gap to Uber, and why StockRank 17 keeps it on the sidelines.
