Your Investment Plan

In this course you’ve learned how prices form, which asset classes exist, how to measure return and risk, value companies, read the macro picture, handle derivatives and why the human brain so often gets in the way of investing. This final lesson brings it all together into a personal plan you can write down and use for decades.

Why a written plan?#

Professionals such as pension funds work with an investment policy statement – a document setting out goals, risk budget, allocation and rules. Individuals benefit at least as much. An investment plan:

• forces you to clarify your goals,
• makes decisions in calm times that you’d otherwise make emotionally in a crisis,
• makes your strategy reviewable – including by yourself five years from now.

The five building blocks#

1. The foundation#

Before money goes into the market:

• Emergency fund of three to six months of expenses in a high-yield savings account or money market fund.
• Pay off expensive debt – credit cards, consumer loans.
• Insure catastrophic risks – liability, disability, and life insurance if others depend on you.
• Capture free money: if your employer matches retirement contributions, contribute at least enough to get the full match.

2. Goals and time horizons#

Write your goals down concretely – with an amount and a date:

Different goals tolerate different risks. Money you need in two years doesn’t belong in stocks. Money you need in thirty years can ride out stock market swings.

3. Asset allocation#

Decide how to split your long-term money between stocks, bonds and cash – as described in Savings Plans and Asset Allocation. Test it with one honest question: would I still hold this mix after stocks fall 30–40%? If not, choose fewer stocks.

Write down limits too: individual stocks at most 10% of the portfolio, no single stock above 5%, no leverage, no products I can’t explain in two sentences.

4. Implementation#

Only now do products come in. For most investors a few broad, low-cost building blocks are enough:

• one or two stock index funds covering the US and the rest of the world,
• a high-quality bond fund or cash as the safe portion,
• perhaps a small, deliberately chosen extra.

Prefer low costs, a solid broker and the most tax-efficient account types available to you.

5. Rules#

This is where a plan’s real strength lies:

• Contributions: “On the 1st of every month, $X goes automatically into my funds.”
• Rebalancing: “Once a year in January, or whenever an asset class drifts more than 5 percentage points.”
• Crises: “When markets fall, I don’t sell. I reread this plan, keep contributing and rebalance into stocks if needed.”
• Reviews: “Once a year and after major life events.”

The most common mistakes#

1. Investing without a foundation – and being forced to sell at the wrong time.
2. Taking too much risk – because the last few years were good.
3. Paying too much – expensive funds, high advisory fees, frequent trading.
4. Market timing – waiting for the perfect entry or bailing before the supposed crash.
5. Concentration – in one stock, one sector, your home country or your employer.
6. Products you don’t understand – leveraged products, complex structured notes, promised guaranteed returns.
7. Procrastination – the most expensive of all, because time is compounding’s strongest force.

Your tools#

For planning, you can use the calculators on this site:

• Compound interest and savings plan – how much your contributions can grow,
• Inflation calculator – what your goal means in future purchasing power,
• Fee calculator – what costs do over the years,
• Loss and recovery – how deep things can go and what that means.

In closing#

Investing isn’t a game you win through cleverness but one you avoid losing through patience, discipline and low costs. You don’t need to follow the market daily, understand every headline or predict the next trend. You need a sensible plan – and to stick with it.

That completes the learning path. To go deeper on any topic, the glossary explains more than 200 terms, and the news section lets you watch what you’ve learned play out in the markets every day.
