Shankman Plain Vanilla Wealth-Building System

Last updated: 23 September 2026

Apply a repeatable, diversified, automation-first investing methodology so you accumulate serious wealth over time without needing to pick winners, time the market, or take unnecessary risk.

// TL;DR

The Shankman Plain Vanilla Wealth-Building System is a repeatable, automation-first investing methodology that helps you build serious wealth without picking winners, timing the market, or taking unnecessary risk. It works by paying yourself first, prioritizing time horizon, using only diversified ETFs and mutual funds, automating contributions to remove emotion, and matching each goal to the right account type. Use it when you're setting up or auditing your personal investing system — at the start of a new year, after a major life event like a new job, marriage, or child, or when deciding how to allocate money across accounts and asset classes.

Framework

// When should you use the Shankman Plain Vanilla Wealth-Building System?

Use this skill whenever a user wants to build or audit their personal investing and savings system — at the start of a new year, after a life event (new job, marriage, child), or when deciding how to allocate money across account types and asset classes.

// What information do you need before applying this system?

Age and time horizonrequired
User's current age and target retirement age or goal date, since time horizon is the single most important factor in every decision.
Employment typerequired
Whether the user is employed by a company, self-employed, works for a nonprofit or government — determines which retirement account types are available.
Household income and rough annual expensesrequired
Needed to size savings contributions and identify how much is available after paying yourself first.
Existing accounts
Any retirement accounts, IRAs, brokerage accounts, or old 401ks the user already holds — including where they are held and how they are currently invested.
Specific financial goals beyond retirement
E.g. children's bar/bat mitzvah, wedding, home renovation, down payment — these determine which non-retirement buckets are needed and their time horizons.
Risk comfort level
Self-assessed appetite for volatility, recognising that most people claim higher tolerance than they actually have when markets fall.

// What are the core principles behind plain vanilla wealth-building?

Pay Yourself First

Before any other expense is considered, move money into retirement and savings accounts the moment income arrives. If you don't see it in your checking account, you won't spend it — you'll figure out how to live on what remains. This is Rule Number One.

Time Horizon Is the Key to Investing

The most important factor in any investment decision is how much time the money has to grow. A smaller amount invested early, compounding over decades, will outperform a larger amount invested late. Starting at 25 with modest contributions beats starting at 45 with large ones.

Singles and Doubles, Not Grand Slams

The goal is not to achieve the highest possible returns. The goal is consistent, modest gains over the long term while minimising missteps. Survivorship bias causes people to celebrate grand slams and forget the losers — don't build your strategy around outliers.

Plain Vanilla Investments

Stick to publicly traded stocks and bonds accessed through diversified ETFs and mutual funds. You do not need alternative investments, private equity, hedge funds, private credit, or individual stock picks. Everything you need to accomplish your financial goals is available in public markets.

Diversification Always Means Apologising for Something

A truly diversified portfolio will always have a laggard — one area that is underperforming right now. That is normal and correct. Diversification means you are never the highest performer and never the lowest; it is the mechanism that protects you when one area gets clobbered.

Remove the Emotion from the Process

Automate contributions so money moves without requiring a decision each time. Emotions cause investors to sell at the bottom and buy at the top. Automation removes that failure mode entirely.

Money Is a Tool, Not a Scorecard

Accumulation is the means, not the end. Spend money on experiences and things that genuinely enhance your life, while meeting savings targets. There is no prize for being the richest person in the graveyard.

Avoid the Two Hard Pile

If you do not understand an investment — its thesis, its structure, its risks — place it in what Charlie Munger called the 'too hard pile' and move on. You do not need access to every new idea or trend.

Sequence of Returns Risk

Withdrawing heavily from a portfolio that is simultaneously falling in value can shave years off how long your money lasts. Someone retiring into a down market without a cash cushion may run out of money a decade earlier than projected.

// How do you apply the Shankman system step by step?

1
Identify every retirement account type available to the user based on their employment
For-profit employee → 401k or Roth 401k. Nonprofit → 403b. Government/hospital → 457 plan. Self-employed → Solo 401k or SEP IRA. Anyone → Traditional or Roth IRA (subject to income limits). Survey what is available through the employer first, because employer plans have higher contribution limits and no income restrictions.
2
Set contribution to the maximum allowed the moment the first income of the year arrives
As of 2026, employee 401k limit is approximately $24,500. If over 50, add $8,000 catch-up ($32,500 total). If aged 60–63, the catch-up is $11,500 instead ($36,000 total). If employer offers a match, contribute at minimum enough to capture the full match — this is free money. If the user cannot max out, start somewhere: 10–15–20% of income as a savings rate is the habit that matters, not the dollar amount.
3
Choose Roth over Traditional where possible
Roth contributions are post-tax; growth is tax-deferred; withdrawals are tax-free. The user never shares that pool of assets with the IRS. There are also no Required Minimum Distributions with a Roth. Avoid getting paralysed trying to predict future tax rates — the key is that you are saving, and Roth provides more certainty and flexibility.
4
Verify the retirement account is actually invested — not sitting in cash or a money market fund
Contributing to a 401k and leaving it in cash is a major and common error. At minimum, move it to a target-date fund or a simple set of equity index funds. Savings in cash will be eaten by inflation and will not outpace it. The investment must be in the stock market to grow purchasing power over time.
5
Consolidate any orphaned old 401ks and IRAs into a single platform
Accounts scattered across many institutions are difficult to track, easy to lose, and hard to manage if something happens to the account holder. Roll old employer 401ks into a Roth IRA where appropriate. Once consolidated, verify the beneficiary designations on every account — an outdated beneficiary (e.g., an ex-spouse) overrides a will and cannot be reversed.
6
Open additional goal-specific accounts for pre-retirement financial goals
Retirement accounts penalise early withdrawal before age 59½. For goals with shorter time horizons (home renovation, weddings, bar/bat mitzvah, a car), open a taxable brokerage account. Nickname sub-accounts for each goal so ownership stays with the user and money can be used flexibly. Do not use UGMA/UTMA accounts for goals you control, because that money legally belongs to the child once they reach age of majority and they can spend it however they choose.
7
Match the investment vehicle to the time horizon of each goal
Goal in under 3–6 months → high-yield savings or money market account, no market risk. Goal in 3–10 years → taxable brokerage account, invested in the market. Goal 10+ years away → retirement account with aggressive equity allocation. The shorter the time horizon, the less market risk is appropriate.
8
Build a diversified portfolio using only ETFs and mutual funds — no individual stocks
Individual stocks are effectively speculation. Any single company, no matter how dominant, can suffer catastrophic loss (use the Boeing example: near-monopoly, blue-chip, dividend cut, stock halved). ETFs and mutual funds mean no single company failure can ruin the portfolio. Spread exposure across: US large cap, US small cap and mid cap, international developed markets, emerging markets, real estate (as a carved-out sector), and bonds. Do not carve out individual sectors beyond real estate — concentrated sector bets can underperform for 10–15 years.
9
Assign the Cowboy Account for any urge to speculate
Human nature creates the itch to bet on an exciting stock or trend. Contain it: allocate 5% or less of investable assets to a Cowboy Account and do whatever you want inside it. If it grows beyond 5% of the portfolio, take profits and move the excess into the serious money account. If it goes to zero, it does not derail financial plans. This preserves the discipline of the core portfolio while satisfying the speculative impulse.
10
Automate all contributions and eliminate notifications
Set up automatic monthly transfers from checking into each account: retirement, taxable brokerage, and goal-specific accounts. Invest automatically according to a pre-decided allocation. Turn off investment app notifications — frequent checking encourages emotional trading decisions. At year-end, review income and expenses from the prior year, then adjust monthly automated amounts for the coming year. Any windfall (bonus, good business year) can be added as a lump sum at that point.
11
Apply the Retirement Drawdown Safety Check for users approaching retirement
Do not enter retirement with 100% equity exposure. Build a cash cushion covering 2–3 years of expenses so the user can ride out a market downturn without forced selling. Review sequence of returns risk: withdrawing heavily from a falling portfolio can permanently shorten how long money lasts. Consider delaying Social Security to lock in a higher, inflation-indexed income stream. Target-date funds are a reasonable accumulation tool inside 401ks with limited options, but they are not a one-size-fits-all retirement strategy.
12
Perform an annual January review checklist
Each January: (1) Confirm retirement contributions are set to maximum. (2) Confirm automated contributions to all goal accounts are active. (3) Review prior year income and expenses; adjust monthly savings amounts. (4) Check all beneficiary designations — update any that are stale. (5) Verify all accounts are invested correctly, not sitting in cash. (6) If the portfolio is heavily concentrated in one area (e.g., S&P 500 / large cap tech), use new contributions to build up underweight areas rather than selling at a high.

// What does this system look like in real-world scenarios?

A 28-year-old salaried employee at a for-profit company, earning a moderate income, with $4,000 available to invest this year and no prior savings habit.

Time horizon is the biggest asset here — emphasise this strongly. Step 1: enrol in the employer 401k immediately and contribute enough to capture the full employer match (free money). Contribute the $4,000 across the year via payroll deduction; do not wait. Choose the Roth option if available. Step 4: invest in a target-date fund or a simple two-to-three fund portfolio of equity ETFs — not cash. The habit of saving, even at a modest amount, compounded over 35+ years is more valuable than a larger amount started at 45.

A 52-year-old self-employed professional with irregular quarterly income, several old 401ks from past employers sitting untouched, and teenage children whose bar/bat mitzvah costs are approaching.

Step 1: determine Solo 401k eligibility (self-employed). Step 2: contribute the catch-up-eligible maximum ($32,500 for over-50) from the first quarterly payment of the year, immediately upon receipt. Step 5: consolidate all orphaned 401ks into a single Roth IRA — update beneficiary designations on every account. Step 4: verify each account is invested in diversified ETFs, not cash or a single bond fund. Step 6: open a separately nicknamed taxable brokerage account for bar/bat mitzvah costs; invest it according to the number of years until the event — if 3+ years away, market exposure is appropriate; if under 6 months, use a money market account. Do not use a UGMA/UTMA for the simcha fund — keep it in a parent-owned account with a nickname.

A 61-year-old couple, both employed, planning to retire in 4 years, with all savings currently in S&P 500 index funds inside their 401ks.

Concentration risk is the primary concern. The S&P 500 is currently heavily weighted toward tech; a sector correction or lost-decade scenario at the moment of retirement triggers sequence of returns risk. Apply Step 8: use new contributions (not sales, to avoid tax events in tax-advantaged accounts) to build exposure to small cap, international developed, and bond allocations. Apply Step 11: begin building a 2–3 year cash cushion now so that a market downturn in the first years of retirement does not force selling depressed assets. Model Social Security delay as an inflation-indexed income floor. Review target-date fund as a transitional tool but customise the glide path to their specific retirement date and spending needs.

// What mistakes should you avoid when using this system?

Saving into a retirement account but leaving the money in cash or a money market fund — contributing is not enough; the money must be invested in the market to outpace inflation.
Chasing the highest possible returns rather than seeking consistent singles and doubles — survivorship bias makes grand slams look achievable; the losers are never mentioned.
Concentrating heavily in a single sector (e.g., all-in on the S&P 500 which is itself heavily weighted to large-cap tech) and ignoring small cap, international, and bond diversification.
Investing in individual stocks instead of ETFs and mutual funds — a single company, however dominant, can collapse and wipe out a significant portion of the portfolio.
Using UGMA/UTMA accounts for goals the parent controls (e.g., a child's wedding fund) — once the child reaches the age of majority, that money is legally theirs to spend however they choose.
Letting old employer 401ks sit uninvested and forgotten across multiple platforms, making it impossible to manage allocation or ensure correct investment.
Failing to update beneficiary designations after major life events — an outdated beneficiary overrides a will and cannot be legally reversed.
Buying into alternative investments — private equity, hedge funds, private credit, real estate syndications — based on promises that sound too good to be true. You do not need alternatives; everything you need is in public markets.
Letting the speculative itch consume more than 5% of investable assets by not ring-fencing it in a dedicated Cowboy Account.
Entering retirement fully in equities without a cash cushion, making the portfolio vulnerable to sequence of returns risk — withdrawing from a falling portfolio permanently shortens how long the money lasts.
Over-checking investment accounts and allowing mobile notifications to trigger emotional trading decisions.
Treating money as a scorecard rather than a tool — hoarding at the expense of meaningful experiences is as much a planning failure as overspending.

// What key terms should you know for plain vanilla investing?

Pay Yourself First: The practice of moving money into retirement and savings accounts the instant income arrives, before any discretionary spending decisions are made. If you don't see it in your checking account, you won't spend it.
Singles and Doubles: The investing philosophy of targeting consistent, modest gains over time rather than swinging for the highest possible returns. Mitigating missteps matters more than hitting grand slams.
Plain Vanilla Investments: Diversified, publicly traded ETFs and mutual funds covering stocks and bonds. No alternative investments, no individual stock picks, no complex or opaque structures.
Cowboy Account: A ring-fenced account containing no more than 5% of investable assets, used to satisfy the urge to speculate in individual stocks or trends without putting the core portfolio at risk.
Serious Money Account: The core diversified portfolio — as opposed to the Cowboy Account. Profits from the Cowboy Account that push it above 5% are transferred here.
Survivorship Bias: The cognitive distortion of only hearing about investing winners while all the losers are conveniently forgotten. The basis for why you should not build a strategy around individual stock picks or alternative investments.
Sequence of Returns Risk: The danger of experiencing significant portfolio losses at the moment you begin withdrawing from it in retirement. Withdrawing from a falling portfolio can permanently shorten how long your money lasts, potentially by a decade or more.
Time Horizon: How long money has to grow before it is needed. The single most important factor in every investing decision — determining account type, asset allocation, and acceptable risk level.
Too Hard Pile: Charlie Munger's concept, adopted by this methodology: any investment you do not fully understand goes here and is ignored. You do not need access to every new idea to build significant wealth.
Paying Retired [You] First: The reframe for 'paying yourself first' — you are not paying current-you for a luxury; you are paying your future retired self before anyone else gets a claim on your income.
Lost Decade: A period (e.g., 2000–2009) in which the S&P 500 produced approximately zero real returns over ten years. Illustrates why concentration in a single index or asset class creates catastrophic risk for someone whose retirement coincides with such a period.
Diversification Always Means Apologising for Something: The acknowledgment that a properly diversified portfolio will always contain a laggard. This is not a flaw — it is proof the portfolio is correctly constructed to mitigate downside across cycles.

// FREQUENTLY ASKED QUESTIONS

What is the Shankman Plain Vanilla Wealth-Building System?

It's a repeatable, diversified, automation-first investing methodology that builds wealth over time without needing to pick winning stocks or time the market. It combines paying yourself first, prioritizing time horizon, using only public-market ETFs and mutual funds, automating contributions, and matching each account type to a specific goal — aiming for consistent 'singles and doubles,' not risky grand slams.

What does 'plain vanilla investing' actually mean?

Plain vanilla investing means sticking to diversified, publicly traded ETFs and mutual funds covering stocks and bonds — no alternative investments, private equity, hedge funds, private credit, or individual stock picks. The core idea is that everything you need to accomplish your financial goals is already available in public markets, so complex or opaque products just add risk without adding necessary upside.

How do I start investing with this system if I've never saved before?

Start by paying yourself first: enroll in your employer's 401k and contribute at least enough to capture the full match. Choose the Roth option if available, and immediately make sure the money is invested — in a target-date fund or simple equity index funds, not cash. The habit and time horizon matter more than the dollar amount, so even a modest automated 10–15% savings rate compounds powerfully over decades.

How do I match my investments to my financial goals?

Match each goal's investment vehicle to its time horizon. Goals under 3–6 months go in a high-yield savings or money market account with no market risk. Goals 3–10 years away go in a taxable brokerage account invested in the market. Goals 10+ years away go in retirement accounts with aggressive equity allocation. The shorter the horizon, the less market risk is appropriate.

How does this compare to picking individual stocks or using a financial advisor for alternatives?

Unlike stock-picking, this system uses only diversified ETFs and mutual funds so no single company collapse can ruin your portfolio — a dominant blue-chip like Boeing can still halve in value. Unlike advisors pushing private equity or hedge funds, it deliberately avoids alternatives, treating anything you don't fully understand as a 'too hard pile.' The goal is consistent gains and fewer mistakes, not chasing outliers.

When should I use the Shankman system?

Use it whenever you're building or auditing your personal investing and savings system — at the start of a new year, after a life event like a new job, marriage, or new child, or when deciding how to allocate money across account types and asset classes. It's designed for a repeatable annual review, not a one-time setup.

What is a Cowboy Account and why would I want one?

A Cowboy Account is a ring-fenced account holding no more than 5% of your investable assets, where you can speculate on individual stocks or trends without endangering your core portfolio. If it grows beyond 5%, take profits and move the excess to your serious money account. If it goes to zero, your financial plan stays intact. It satisfies the speculative itch while preserving discipline.

Should I choose a Roth or Traditional retirement account?

Choose Roth wherever possible. Roth contributions are post-tax, growth is tax-deferred, and qualified withdrawals are tax-free — you never share that pool with the IRS, and there are no Required Minimum Distributions. Rather than getting paralyzed trying to predict future tax rates, the key is that you're saving at all; Roth simply provides more certainty and flexibility.

What results can I expect from following this system?

Expect steady, compounding wealth accumulation with fewer emotional mistakes — not overnight riches. By automating contributions, diversifying broadly, and matching accounts to goals, you avoid the failure modes that derail most investors: selling at the bottom, chasing trends, and running out of money in retirement. The system optimizes for consistency and downside protection, so you accumulate serious wealth over decades without unnecessary risk.

What is sequence of returns risk and why does it matter near retirement?

Sequence of returns risk is the danger of experiencing major portfolio losses at the moment you begin withdrawing in retirement. Withdrawing heavily from a falling portfolio can permanently shorten how long your money lasts — potentially by a decade. To protect against it, build a 2–3 year cash cushion before retiring so a downturn doesn't force you to sell depressed assets.

Is it enough to just contribute to my 401k?

No — contributing is not enough; the money must actually be invested in the market. Leaving 401k contributions in cash or a money market fund is a common, costly error, because inflation erodes purchasing power over time. At minimum, move the money into a target-date fund or a simple set of equity index funds so it grows.
