Buying your first stock on the Colombo Stock Exchange can feel intimidating. There are hundreds of listed companies, a wall of jargon, and no shortage of tips flying around WhatsApp groups. But professional investors don't rely on tips — they run a checklist. Here is a simple five-step version you can apply to any CSE share before you commit a single rupee.
Before step one: to buy shares you first need a CDS account, which you open through a licensed stockbroker registered with the CSE. It's free, takes your NIC and a few forms, and is the equivalent of opening a bank account for shares. Do this once, and the five steps below become your routine for every purchase after.
The checklist at a glance
- 1. Understand the business — what does it actually sell, and to whom?
- 2. Check that it makes money — profit and revenue, trending the right way.
- 3. Look at the debt — a strong balance sheet survives bad years.
- 4. Judge the price — a great company at a silly price is a bad investment.
- 5. Write down your reason — know why you're buying before you buy.
Step 01 — Understand what the business actually does
It sounds obvious, but most beginners buy a ticker, not a business. Before anything else, be able to explain in one plain sentence how the company earns its money. LIOC sells fuel and lubricants. Commercial Bank lends money and earns interest. John Keells does a bit of everything — hotels, retail, ports, and more.
Ask yourself: is this a business I understand, and one that will still be needed in ten years? If you can't explain what a company does without reading its annual report twice, that's not a reason to feel stupid — it's a reason to move on to one you do understand. There are plenty.
Step 02 — Check that it actually makes money
A share price can rise on hype, but over the long run a company is worth the profits it generates. Open the company's most recent annual report — every listed company publishes one, free, on the CSE website — and look at three things over the last three to five years:
- Revenue — is the top line growing, flat, or shrinking?
- Net profit — is the company consistently profitable, or does it swing into losses?
- Earnings per share (EPS) — profit divided by the number of shares. This is the number that ultimately drives value.
You're not looking for perfection. You're looking for a trend. A company whose profit has grown steadily for five years is telling you something very different from one that lurches between profit and loss.
A rising share price built on a falling profit is a warning, not an opportunity.
Step 03 — Look at how much it owes
Profit tells you how a company did last year. The balance sheet tells you whether it can survive a bad one. Sri Lankan companies lived through a currency crisis and sky-high interest rates recently — the ones that came through in good shape were usually the ones that weren't drowning in debt.
Two quick checks, both found in the annual report:
- Debt-to-equity — how much the company owes versus what shareholders own. Lower is safer.
- Current ratio — short-term assets divided by short-term liabilities. Above 1 means it can cover its near-term bills comfortably.
You don't need to memorise ideal figures. Just compare the company to others in the same sector — a bank's balance sheet looks nothing like a manufacturer's, so only compare like with like.
Step 04 — Judge the price — is it cheap or expensive?
Here's the step beginners skip: a wonderful company bought at a ridiculous price is still a bad investment. Valuation is simply asking, "what am I paying for each rupee of value I get?" Three ratios do most of the work:
The three valuation ratios
- P/E (price ÷ earnings) — how many years of profit you're paying for. Compare to sector peers, not across sectors.
- P/B (price ÷ book value) — the price versus the company's net assets. Below 1 can signal value — or trouble. Ask why.
- Dividend yield — the cash income you earn while you hold. Check the profit actually covers the payout.
No single ratio is a verdict. A low P/E might mean a bargain — or a market that expects profits to fall. The point isn't to find a magic number; it's to make sure you're not overpaying, and to understand why the market has priced a stock the way it has.
Step 05 — Write down why you're buying
Before you place the order, finish this sentence in one line: "I'm buying this because ______, and I expect to hold it for ______." It sounds trivial. It's the single most useful habit an investor can build.
Your written reason does two things. It forces you to have an actual thesis rather than a hunch. And months later — when the price wobbles and your nerve is tested — it reminds you whether anything has genuinely changed, or whether it's just noise.
One last discipline: never put all your money in one stock. Even a perfect checklist can't predict the future. Spreading your money across several good businesses is how you make sure one wrong call doesn't undo everything.
Putting it together
Run all five steps and you'll have filtered out the vast majority of bad decisions before they cost you anything. You'll understand the business, you'll know it makes money, you'll know it isn't fragile, you'll know you're paying a fair price, and you'll know exactly why you own it. That's not a guarantee of profit — nothing is — but it's how disciplined investing actually works.
Start with one company you already understand. Run the checklist. The habit, repeated, is worth more than any single tip you'll ever receive.
