Dollar-cost averaging on UZSE: investing a fixed sum

Many people who want to start investing face the same worry: what if I buy today and the price falls tomorrow? One common answer is dollar-cost averaging, often shortened to DCA. Instead of investing a large sum at once, you invest a fixed amount at regular intervals, for example every month, whatever the price. This guide explains how it works, shows the arithmetic with an illustrative example on the Uzbek market, and is honest about its limits.

What dollar-cost averaging means

Dollar-cost averaging is a simple rule: you decide on an amount, for example 1,000,000 soʻm, and a schedule, for example the first working day of each month, and you buy on that schedule regardless of what the market is doing. Despite the name, it has nothing to do with the US dollar. On the Tashkent Stock Exchange (UZSE) you would do it in soʻm.

Because the amount is fixed, the number of shares you get changes with the price:

• When the price is high, your fixed amount buys fewer shares.
• When the price is low, the same amount buys more shares.

Over time this means your average cost per share tends to sit below the simple average of the prices on your purchase dates, because you automatically bought more of the cheaper shares.

A worked example

The numbers below are purely illustrative. They are not the prices of any real UZSE share and are chosen to divide evenly.

Suppose you invest 1,000,000 soʻm in the same share on the first working day of each month for six months, and the price on those days is:

• Month 1: price 20,000 soʻm, 50 shares bought, 1,000,000 soʻm invested.
• Month 2: price 25,000 soʻm, 40 shares bought, 1,000,000 soʻm invested.
• Month 3: price 12,500 soʻm, 80 shares bought, 1,000,000 soʻm invested.
• Month 4: price 10,000 soʻm, 100 shares bought, 1,000,000 soʻm invested.
• Month 5: price 20,000 soʻm, 50 shares bought, 1,000,000 soʻm invested.
• Month 6: price 25,000 soʻm, 40 shares bought, 1,000,000 soʻm invested.

After six months you have invested 6,000,000 soʻm and own 360 shares.

• Your average cost is 6,000,000 ÷ 360, about 16,667 soʻm per share.
• The simple average of the six prices is (20,000 + 25,000 + 12,500 + 10,000 + 20,000 + 25,000) ÷ 6 = 18,750 soʻm.

Your average cost is lower than the average price because months 3 and 4, when the price was low, gave you more shares. That is the whole mechanism of dollar-cost averaging.

Now compare this with investing the full 6,000,000 soʻm in month 1 at 20,000 soʻm. You would own 300 shares. At the month 6 price of 25,000 soʻm, those would be worth 7,500,000 soʻm, while the DCA portfolio of 360 shares would be worth 9,000,000 soʻm. In this example DCA did better, but only because the price dipped in the middle.

When dollar-cost averaging does worse

It is important to see the other side. Imagine the price had risen steadily instead: 20,000, 22,000, 24,000, 26,000, 28,000 and 30,000 soʻm. A lump sum invested in month 1 would have bought everything at the lowest price. Spreading the purchases would have meant paying more and more each month, and you would end up with fewer shares than the lump-sum investor.

So dollar-cost averaging does not guarantee a better result. When prices mostly rise, investing earlier usually wins. When prices fall and then recover, spreading your purchases often looks better. Nobody knows in advance which path the market will take.

What DCA really offers is:

• Less timing risk. You avoid putting everything in at one unlucky moment.
• A habit. Investing on a schedule, from income, turns investing into a routine rather than a series of anxious decisions.
• Less emotion. A fixed rule makes it harder to buy in excitement after a sharp rise or to stop out of fear after a fall.

What it does not offer is protection against a long decline. If a company's business deteriorates and the share keeps falling for years, buying more of it every month means more money in a falling asset. DCA is a way to enter an investment, not a way to judge whether the investment is sound.

Practical points for UZSE investors

A few features of the Uzbek market are worth keeping in mind when you plan regular purchases.

Whole shares and leftover cash. On an exchange you usually buy whole shares, so a fixed amount rarely converts exactly. If a share costs 16,000 soʻm, 1,000,000 soʻm buys 62 shares for 992,000 soʻm and leaves 8,000 soʻm. Many investors simply let the leftover carry into the next month.

Commissions. Each purchase through a broker can carry a commission, and some tariffs include a minimum charge per order. If you invest small amounts very often, those charges can take a noticeable share of each purchase. Ask your broker for its current tariff and choose a frequency, monthly or quarterly, where fees stay a small part of what you invest.

Liquidity. Some UZSE shares trade rarely, and the price at which you can buy may be far from the last trade. Before committing to a schedule, check how often a share actually trades. The exchange publishes trade results on uzse.uz, and Finmind's stocks pages show recent prices and history for listed shares.

Diversify the schedule. Dollar-cost averaging into a single share still leaves you exposed to that one company. You can split each monthly amount across several shares, or alternate between shares and bonds. Diversification and risk explains why this matters.

Keep an emergency fund first. Regular investing works best when you will not need to sell at a bad moment to cover an unexpected cost. See emergency fund and budgeting.

How to set up your own plan

1. Pick an amount you can sustain. It should come from your regular income after essential spending and saving, so that you can keep going through a bad year in the market.
2. Pick a schedule. Monthly is common because it matches most salaries. Write the date down and treat it like a bill.
3. Decide what you will buy. Choose the shares or bonds in advance, based on your own research, rather than on the day of purchase.
4. Record every purchase. Note the date, price, number of shares and fees, so that you always know your real average cost. A portfolio tracker does this for you.
5. Review, but not too often. Look at the plan once or twice a year. Changing course every time the market moves defeats the purpose.
