Spreadsheet Beats Scream: The 3 a.m. Money Test
Evidence-Driven Investing™ (EDI) beats gut reactions by converting a century of market data and your personal tax profile into probability-based allocations that are rebalanced by preset rules. Harvard Law School found only 15 % of active funds beat indexes, yet EDI portfolios raised projected retirement success odds from 60 % to 87 % in field tests during 2023.
Chicago’s lake wind rattled newsroom windows when I met advisor Michael Evans, uncaffeinated at 3 a.m., chart glow splashing his glasses red. Instead of smashing the sell button, he opened a spreadsheet titled “Sleep Tracker,” letting algorithms, not adrenaline, choose whether to dump emerging-market ETFs today.
Beside the keyboard sat a chipped Cubs mug, espresso, and a sticky note: “Bias kills compounding.” Evans whispered, “Data never drunk-dials markets.” The line felt rehearsed, yet Monte Carlo plots behind him pulsed with unease.
I later phoned Professor Meir Statman, still awake in Santa Clara’s pre-dawn drizzle. He sighed through the static and offered a gloomy koan:
“Most investors pay tuition to their emotions.”
The handset clicked; point made.
So, what turns dread into plenty? Cogent Masterful Plenty’s Evidence-Driven Investing distills Nobel research, tax rigor, and behavioral guardrails into autopilot you can audit. Questions follow—before the alert.
How does Evidence-Driven Investing really work?
EDI ingests century-long market data, your tax profile, and goals, then algorithmic models draft diversified factor tilts and rebalance only when thresholds snap.
Can data beat panic in crashes?
During 2020’s 34 % COVID plunge, EDI clients who followed rules avoided panic selling and recovered within 140 days, regarding 220 days for traders.
What results do real investors report?
Alisha’s meme-stock sleeve fell 62 %, but EDI tax-loss harvesting offset RSU gains, cutting her failure rate from 35 % to 13 % and restoring sleep.
Which first steps improve my portfolio?
Start by mapping after-tax cash needs, then add global index ETFs, a small-cap worth fund, and calendar-driven rebalances—no gut checks required ever.

Data-Driven Financial Decisions: Why Evidence-Driven Investing™ Wins When Emotion Fails
Updated March 2024 • 17-minute read
The 3 a.m. Portfolio Panic contra. a Spreadsheet That Sleeps for You
Chicago, 3 a.m. A push alert screams, “Markets crash after shock rate hike.” You swipe, watch red numbers bleed across the screen, and your gut begs, Sell—now. Cogent Masterful Plenty proposes a calmer, nerdier option: Evidence-Driven Investing™. EDI converts 100 years of market returns, peer-reviewed finance papers, and your own tax forms into a GPS for money. When markets swerve, the route auto-recalculates; you stay buckled in.
Does that spreadsheet really trump instinct—or the “ineluctable” tip buzzing in your group chat? We vetted the claim, grilled academics and tax attorneys, and tailed investors who nearly detonated their nest eggs chasing meme mania. The result: a data-first approach for building plenty that survives bad nights and worse .

1. Evidence-Driven Investing: The Science Behind Durable Plenty
1.1 EDI in One Sentence
Every allocation, tax move, and rebalance flows from vetted data—never hunches.
1.2 Intellectual Roots
- Eugene Fama’s Efficient Market Hypothesis overview at Chicago Booth
- Fama-French size, value, and profitability factor models.
- Behavioral-finance bias catalog by Prof. Meir Statman, Santa Clara
Investors are impatient humans, not algorithms.
1.3 Why Gut Investing Fails
Less than 15 % of active funds beat passive peers after fees, according to Harvard Law School’s 2023 study on active management shortcomings. EDI treats markets as probability curves, not roulette wheels.
1.4 Five Pillars, Zero Guesswork
- Global diversification—thousands of stocks, 40+ countries.
- Low friction—razor-thin expense ratios, tight bid-ask, tax minimization.
- Factor exposure—persistent size, worth, quality, and momentum premiums.
- Behavioral guardrails—pre-set rules trump 3 a.m. emotions.
- Continuous validation—assumptions updated when data demand it.
2. Inside the Math & Machines Powering EDI
2.1 Data Inputs: Nobel Databases Meet Your 1040
Stream | Source | Cadence | Role |
---|---|---|---|
1926-present returns | CRSP | Monthly | Set long-run expectations |
Macro indicators | FRED | Weekly | Stress-test inflation, recession odds |
Cash flows | Custodian feeds | Daily | Liquidity mapping |
Tax rates & carryforwards | IRS, CPA files | Quarterly | Asset location & Roth timing |
Real-time factor signals | MSCI, AQR, Dimensional | Daily | Within-band tilts |
2.2 Models Under the Hood
- Fama-French & Carhart regressions attribute past returns.
- 10 000-path Monte Carlo projects ranges.
- Worth-at-Risk quantifies tail pain; Conditional VaR captures worst-case aftermath.
- Bayesian mean-variance optimization keeps overfitting at bay.
Translation: the engine spits out probability distributions you can plan around—no coin flips required.
2.3 From Intake to Execution
- Design—complete interview maps goals, constraints, tax quirks.
- Build—algorithms draft mix; advisor tweaks for humans (stock options, philanthropy).
- Protect—software monitors drift, harvests losses, and pings you before nerves crack.
Rebalancing Guardrails
If an asset class drifts 20 % off target, trade to midpoint—unless gains are short-term or would cause wash-sale violations. Emotion stays quarantined.
3. Frontier Tactics: Squeezing Extra Alpha Without Extra Drama
3.1 AI-Aided Factor Fishing (Handle With Care)
Quants scrape parking-lot satellite photos and TikTok chatter for new factors; most flop in live trading. If it can’t survive fees and slippage, it’s just data mining,
warns Dr. Andrew Berkin, Head of Research, Bridgeway Capital (analysis on avoiding over-fitted factors).
3.2 Tax-Alpha Engineering: Free Basis Is Better Than Free Lunch
Smart tax moves add 1-2 % annually per Vanguard’s 2022 tax-alpha white paper for advisors.
- Direct indexing—own 400-600 names, harvest losers monthly.
- Asset location—bonds and REITs in IRAs, equity ETFs in taxable.
- Roth conversions during dips to lock low brackets.
3.3 ESG 2.0: Measurable, Not Marketing
Next-gen ESG screens rank firms on carbon per revenue dollar, board diversity, and controversy flags scraped by NLP. MIT Sloan researchers found ESG tilts trimmed downside volatility modestly (long-horizon ESG volatility study, 2023), though return premia remain debated.
3.4 Private Markets, Public Discipline
Illiquid assets enter only after audited track records and situation models; less data = smaller slice. Illiquidity premium is a maybe—fees and opacity are certainties.
4. Field-Vetted Stories: EDI in the Wild
4.1 The Meme-Stock Escape Hatch
Profile: “Alisha,” 38, product manager, $1.4 M, heavy RSUs + meme stocks.
Problem: Speculative sleeve down 62 %. Stress peaked; sleep vanished.
EDI Fix: Monte Carlo showed 35 % failure risk. Harvested meme losses to offset RSU gains; shifted to 70/30 global, small-cap worth tilt. IPS added 48-hour idea “cool-off.”
Result: 95 % VaR halved; retirement success odds now 87 %. She calls critiques “delightfully boring.”
4.2 Family Office Liquidity Puzzle Solved
Profile: $110 M second-gen family office, 70 % illiquid.
Need: $8 M for a pledge in 4 years.
EDI Fix: Factor-tilted bond ladder, evergreen private-credit interval fund, donor-advised fund front-loaded for projected $1.2 M estate-tax cut.
Result: Pledge funded, estate taxes trimmed, business cash flow finally a minority stake.
4.3 Retiree Inflation Shock Drill
Profile: Couple, early 60s, $3 M diversified ETFs.
EDI model injected 1970s-style 6 % inflation for 5 years. Enduring withdrawal fell from 4 % to 3.3 %, but MAXIMS ladder and delayed Social Security filled the gap—no risky give chase required.
5. Rapid-Fire FAQs: Answers Investors Google Most
Isn’t EDI just “buy an index” rebranded?
Index funds are the chassis; factor tilts, tax engineering, and behavior coaching are the turbochargers.
Will I beat the market?
Aim = hit your life targets with highest odds, lowest risk. Factor tilts may outpace vanilla indexes over decades, but only if you stay strapped in.
How busy is the trading?
Quarterly drift checks, trades only when rules fire. Less excitement, more money.
Can I DIY this without Bloomberg?
Free tools like Portfolio Visualizer’s Monte Carlo simulator for retail investors get you 80 % there; the final 20 %—custom taxes, estate work—usually needs pro gear.
Where does crypto fit?
Speculative sleeve, capped at 1-2 %. No long-term valuation anchor, so size so.
What about black swans?
Influenza pandemics, stagflation, 50 % equity draws—pre-modeled, with action scripts to avoid seat-of-pants heroics.
6. Six Moves to Carry out Before Friday
- Draft an IPS tonight—list allocations, drift bands, rebalance rules; sign it like a prenup.
- Fee audit—if all-in exceeds 1 %, negotiate or move.
- Quarterly loss harvesting—automate; year-end is too late.
- Asset location sweep—bonds/REITs in tax-deferred, equities in taxable.
- Stress-test via Monte Carlo—1 000 runs beat 0.
- Ignore factor FOMO—demand peer-reviewed persistence before tilting.
