Saving protects money. Investing accepts the possibility of losing some of it in exchange for the possibility of growing it faster than prices rise. The difference between the two is not the product; it is whether the value can fall.

Before investing anything

Two conditions are described almost universally as coming first, and the reasoning behind each is arithmetic rather than opinion:

1. An emergency fund exists. Without one, an unexpected cost forces selling investments at whatever price happens to prevail that week — often a poor one, since financial strain and falling markets tend to arrive together.
2. High-interest debt is addressed. Clearing a balance costing 24 per cent a year removes a cost of 24 per cent a year. That saving is certain, where an investment return is not.

Risk and return

Higher potential return comes with higher potential loss. There is no arrangement offering high returns with no risk, and a presentation claiming otherwise is describing something other than what it says it is. Lesson 6's Rule of 72 is a quick test: a promise to double money in a year implies roughly a 72 per cent annual return.

The kinds of risk

• Market risk: prices fall.
• Inflation risk: the return does not keep pace with prices. This is the risk of holding everything in cash.
• Liquidity risk: the money cannot be reached quickly, or only at a poor price.
• Concentration risk: too much of the total in one company, one industry or one country.
• Currency risk: holdings in another currency move with the exchange rate, as lesson 31 describes.

Avoiding one risk usually means accepting another. Cash avoids market risk and accepts inflation risk in full.

Time changes the picture

Over a year, the value of a share or a fund may do almost anything. Over twenty years, the range of outcomes has historically been narrower, because short-term movements have time to average out and because the compounding described in lesson 6 has time to work.

This is why the horizon drives the decision. Money needed within a couple of years generally sits in savings. Money not needed for decades is where investing is usually discussed, because there is time to recover from a fall.

Spreading out

Diversification means holding a mix, so that one bad outcome does not determine the result. A mix can span companies, industries, asset types — shares, bonds, property, cash — and countries.

What it does: reduces the damage from any single failure. What it does not do: protect against a fall affecting everything at once. Lesson 26 covers both sides properly.

The routes available locally

• Mutual funds and unit trusts: a pooled fund holding many investments, managed professionally, bought in units. Often the starting point, because diversification comes built in. Lesson 25 covers how they work and what they charge.
• Shares on the Trinidad and Tobago Stock Exchange: direct ownership in listed companies, bought through a registered broker-dealer. Lesson 28 covers the mechanics.
• Government securities: treasury bills and bonds, covered in lesson 27.
• Property: familiar locally, and distinctive in needing a large sum, in being slow to sell, and in carrying ongoing costs.
• A pension or retirement plan: an investment arrangement with specific rules, covered in lessons 12 and 35.

Costs and the questions to ask

Every route charges something, and those charges compound against the investor exactly as returns compound for them. Lesson 30 shows the size of that effect over a working life. Before committing money anywhere:

1. Is the person or firm registered with the Trinidad and Tobago Securities and Exchange Commission?
2. What are all the charges — entry, annual, exit?
3. How quickly can the money be taken out, and at what cost?
4. What is the realistic range of outcomes, including the bad ones?
5. Is anything here guaranteed, and by whom?

Pressure to decide immediately, reluctance to put terms in writing, and returns described as guaranteed and high are the three signals our Scam Watch page returns to most often.
