Diversification and risk: how to spread your investments
Finmind editorial team · · Updated · 8 min read
What investment risk really means, why putting all your money in one share is dangerous and how diversification across assets and issuers reduces risk.
In short
Diversification means spreading your money so that one bad outcome does not ruin your whole plan.
It cuts the risk of a single company failing, but it cannot protect you from a fall of the whole market.
Spread across companies, industries, kinds of asset, bond issuers and time.
On a smaller market, watch how often a share trades and keep costs in mind before adding many small positions.
An emergency fund comes first, and rebalancing once or twice a year keeps your mix on track.

"Do not put all your eggs in one basket" is probably the oldest investment advice there is. It describes diversification: spreading your money across different investments so that one bad outcome does not ruin your whole plan. This guide explains what risk means for an investor, which kinds of risk diversification can reduce and which it cannot, and how to think about it on the Uzbek market.
What risk means for an investor
In everyday language, risk means the chance that something goes wrong. For an investor it has a few related meanings:
Price swings (volatility). The value of an investment moves up and down, sometimes sharply. If you have to sell during a dip, a temporary fall becomes a real loss.
Permanent loss. A company can fail, or a bond issuer can stop paying. In that case the money may never come back.
Not reaching your goal. Money that is too cautious can lose purchasing power to inflation, so avoiding all risk carries a risk of its own. See inflation and your savings.
Risk and potential return are linked. Investments that can grow more usually swing more along the way. There is no investment with high expected returns and no risk, and any offer that promises one deserves suspicion.
Two kinds of risk
It helps to split risk into two parts.
Specific risk belongs to a single company or issuer. A factory fire, a lost contract, poor management or a dividend cut hits one company and its shareholders. Other companies may not be affected at all.
Market risk affects almost everything at once. A slowdown in the economy, a jump in interest rates or a sharp change in the exchange rate can push many prices down together. How interest rates play into this is covered in interest rates and the CBU policy rate.
Diversification is very good at reducing specific risk. It is much weaker against market risk, because when the whole market falls, most holdings fall with it.
How diversification works
Here is a simple, hypothetical example with round numbers.
Suppose you invest 10,000,000 soʻm. In the first case, you put it all into the shares of one company. In the second case, you split it equally across ten companies from different industries, 1,000,000 soʻm each.
Now imagine that one of those companies runs into serious trouble and its share price falls by half.
In the first case, your whole portfolio falls by 50%, to 5,000,000 soʻm.
In the second case, only one tenth of your money was in that company, so your portfolio falls by 5%, to 9,500,000 soʻm, if the other nine stay flat.
Of course, the reverse is also true: if that single company had doubled, the concentrated portfolio would have gained far more. Diversification gives up the chance of a spectacular result from one bet in exchange for a smoother and more reliable path. For most people saving for real goals, that trade is worth it.

Ways to diversify
There are several layers of diversification. Each one addresses a different source of risk.
Across companies. Hold shares of several issuers rather than one. You can browse the shares traded on UZSE on the stocks page.
Across industries. Companies in the same industry often rise and fall together. Owning a bank, a manufacturer and a telecom company is more diversified than owning three banks.
Across asset classes. Shares, bonds, deposits and other assets react differently to the same events. Bonds and deposits can soften the swings of shares. Read stocks vs bonds for the differences, and see listed bonds on the UZSE bonds page.
Across issuers of bonds. Even with bonds, avoid relying on one borrower, since each carries its own credit risk.
Over time. Investing a fixed amount at regular intervals, instead of everything at once, means you buy at many different prices. This reduces the risk of putting all your money in at an unlucky moment, although it does not protect you from a long decline.
An emergency fund is the foundation under all of this. If you keep a cash cushion for unexpected costs, you are less likely to be forced to sell investments at a bad time. See emergency fund and budgeting.
Do
Hold shares of several issuers rather than one.
Spread across industries, not three companies from the same one.
Mix asset classes: shares, bonds and deposits react differently.
Keep an emergency fund so you are not forced to sell at a bad time.
Don't
Rely on one borrower, even with bonds.
Put all your money in at one unlucky moment.
Diversification on a smaller market
The Uzbek stock market is smaller than the largest markets in the world, and that shapes how you diversify.
Fewer choices. The number of listed companies is limited, and some industries are represented by only a few issuers. It may take more care to spread money across genuinely different businesses.
Liquidity. Some shares trade rarely. A portfolio of many thinly traded shares may look diversified on paper but be hard to sell when you need cash. Check how often a share trades before you buy it.
Costs. Every purchase has commissions and fees. Spreading a small amount over too many positions can make costs eat a large share of your return. A few well-chosen holdings may be more sensible than many tiny ones.
Checking what you own. Read issuers' disclosures on openinfo.uz to understand what each company does. Two shares with different names can depend on the same risk.

Keeping your mix on track
Over time some holdings grow faster than others, and your portfolio drifts away from the mix you planned. Rebalancing means periodically bringing it back, for example by adding new money to the parts that have fallen behind. Many investors review their mix once or twice a year rather than reacting to every price move.
Finmind can help you see this in practice. On the free simulator, available after you create a free Finmind account, you can practise building a diversified portfolio with virtual money and watch how it behaves, with no real money involved. The free tutorials also cover risk and portfolio building. If you later connect your brokerage account, your portfolio view shows your real holdings in one place.
Frequently asked questions
No. Diversification reduces the damage from any single company or issuer going wrong, but it cannot protect you from a fall of the whole market. When many prices drop together, a diversified portfolio will usually fall too, just typically less than a concentrated one.
There is no exact number. What matters is that your holdings depend on different risks: different companies, different industries and different asset classes. A few holdings in unrelated businesses can be more diversified than many holdings in one industry. Costs also matter, so avoid splitting a small amount into too many tiny positions.
Yes, deposits are a different asset class from shares and bonds, and they behave differently. They can make a portfolio steadier and keep money available for emergencies. Their return can fall short of inflation, though, so relying only on deposits carries a risk of losing purchasing power.
Specific risk comes from one company or issuer, such as poor results or a missed payment, and diversification reduces it well. Market risk affects most investments at once, such as an economic slowdown or a change in interest rates, and diversification reduces it only a little.
