## High and safe, please

**Alex Tutor:** You're still helping Dana, and now it's money for the long run.

**Dana:** The emergency fund is done, the kitchen money is placed. Now I can put 3,000 a month aside for the long run, twenty years or so. I want a high return and no risk.

**Alex Tutor:** Everyone wants that, which is exactly why it doesn't exist. If something paid a lot with no risk, everyone would buy it, its price would rise, and the return would shrink. Higher expected return is the payment for accepting bigger swings.

**Alex Tutor:** Here are twenty invented years of three made-up options, after inflation: something cash-like, a bond fund and a share index fund. Not history, not a forecast, just the typical shape.

**Invented real returns of three options, years 1–20, %**

| Year | Cash-like | Bond fund | Share index fund |
| --- | --- | --- | --- |
| 1 | 3 | 5 | 12 |
| 2 | 3 | 3 | -8 |
| 3 | 2 | 7 | 21 |
| 4 | 2 | 4 | 15 |
| 5 | -1 | -6 | -28 |
| 6 | 0 | 9 | 6 |
| 7 | 2 | 4 | 9 |
| 8 | 3 | 3 | 4 |
| 9 | 3 | 6 | 18 |
| 10 | 2 | 1 | -5 |
| 11 | 2 | 5 | 11 |
| 12 | 2 | 6 | 23 |
| 13 | 2 | -3 | -14 |
| 14 | 1 | 4 | 7 |
| 15 | 2 | 5 | 16 |
| 16 | 2 | 3 | 2 |
| 17 | 3 | 2 | -3 |
| 18 | 3 | 6 | 19 |
| 19 | 2 | 4 | 10 |
| 20 | 2 | 2 | 5 |

*Invented for teaching: averages 2% (cash-like), 3.5% (bonds) and 6% (shares); worst years −1%, −6% and −28%.*

**Dataset (CSV):** [Invented yearly returns, after inflation](https://productovi.com/datasets/personal-finance/risk-and-return/invented-yearly-returns.csv)

Twenty invented years for teaching, not a real series or a forecast.

- `year`: Year 1–20
- `cash_like_pct`: Cash-like savings, % after inflation
- `bond_fund_pct`: Bond fund, % after inflation
- `share_index_pct`: Share index fund, % after inflation

**Sofia:** The share index has the tallest bars both ways.

**Alex Tutor:** That's **volatility**: how far returns swing from year to year. Count the years the share index lost money.

> **Exercise:** In how many of the 20 invented years did the **share index fund** lose money (a return below zero)?

## Why the average flatters

**Dana:** Five bad years out of twenty. But on average it still made 6% a year, the best of the three.

**Alex Tutor:** On a simple average, yes. But 100,000 compounded through those twenty years ends at 275,589, which is 5.2% a year, not 6%. Losses hurt more than the same-sized gains help.

**Sofia:** Because after a fall you're growing from a smaller base.

**Alex Tutor:** Exactly. Take year 5: minus 28%. How much does the fund then have to rise just to get back to where it was?

> **Exercise:** In year 5 the share index fund fell 28%. By **what percentage** must it then rise to get back to its value before the fall? Two decimals.

## Time decides how much risk fits

**Dana:** 38.89% just to break even. And in year 5, 100,000 would have turned into 72,000. I'd panic.

**Alex Tutor:** Many people do, and they sell at the bottom. That turns a drop on paper into a real loss. The best protection is not needing that money soon.

**Alex Tutor:** Money for next year can't wait out a −28% year. Money for twenty years can wait out several. So the time until you need the money decides how much swing it can carry.

**Sofia:** That's why the kitchen money went into deposits and bonds, not shares.

> **Exercise:** Match each of Dana's pots of money with the invented option whose swings it can live with.

## The promise test

**Dana:** A friend from my book club keeps sending me an offer: 25% a year, guaranteed, "no risk at all".

**Alex Tutor:** Then you already know the most important thing about it. In our invented chart, even the riskiest option averaged 6% a year with a −28% year in it. Anything promising much more with no risk is either hiding the risk or isn't real.

**Sofia:** So "high" plus "guaranteed" is a warning sign in itself, before checking anything else.

**Alex Tutor:** Yes. We'll come back to how such schemes work at the end of this module.

> **Exercise:** **True or false:** an offer of 25% a year "guaranteed, with no risk" is a warning sign in itself, before you check who is behind it.

## Returns as a range

**Dana:** So what do I tell myself about the share index? "About 6% a year"?

**Alex Tutor:** Say a range and a bad year. Here: about 5% a year compounded over twenty years, with single years from −28% to +23%. A different twenty years could be better or worse.

**Sofia:** And after fees, which we haven't even counted yet.

**Alex Tutor:** Right, that's lesson three. For now: return and risk come as a pair. Pick the swings you can live through, then accept the return that comes with them.

> **Exercise:** Which description of the invented share index fund is the most **honest**?

## Your turn: Dana's risk in three sentences

**Dana:** Help me write it down before I start, so I remember it in a bad year.

**Alex Tutor:** Three things: how long the money stays invested, how big a fall Dana can watch without selling, and what return range she expects in exchange.

**Sofia:** With a number for the fall, in hryvnias, not just a percentage.

**Dana:** Yes. "Minus 28%" sounds abstract. "Minus 28,000" doesn't.

> **Exercise:** Write Dana's risk note in 3 sentences: how long the 3,000 a month stays invested, how big a fall she should expect to sit through without selling (in hryvnias on 100,000), and what return range she expects in exchange.

> **Key ideas**
>
> - Return is payment for risk: there's no "high and safe". A promise of both is a warning sign.
> - In the invented series, the share index had the highest average (6%) and the most swings: 5 losing years out of 20, the worst −28%.
> - Averages flatter: compounded, the same years give 5.2% a year (100,000 → 275,589). A 28% fall needs a 38.89% rise to recover.
> - The time until you need the money decides how much **volatility** it can carry: money for next year doesn't belong in shares.
> - Describe returns as a range with a bad year, after fees and inflation, never as a promise. This is educational, not personal financial advice.

**Alex Tutor:** Next: how to take market risk without betting on any single company.
