How to Invest in the NSE: CDS Account, Broker, Costs and Your First Trade
You can start investing in the Nairobi Securities Exchange (NSE) without walking into a trading floor or having a large portfolio. Today, the process can be completed through a licensed intermediary and, in some cases, digitally.
But before you press "Buy", you need to understand three things: where your shares are held, who executes your trade and what you will actually pay.

Here is the process from beginning to end.
1. Start with a financial check
Before opening an account, decide how much you can comfortably invest.
The Capital Markets Authority (CMA) advises investors to consider their financial objectives, income, constraints and risk tolerance before entering the capital markets. It also cautions beginners against borrowing money to invest.
Your first question should therefore be:
"How much can I invest without putting my essential expenses at risk?"
You do not need to start with a huge amount. What matters is investing an amount appropriate for your circumstances and understanding that share prices can rise or fall.
2. Open a CDS account
A Central Depository System (CDS) account is the electronic account through which your securities are held.
CDSC explains that investors can open a CDS account through an authorised Central Depository Agent (CDA), including a stockbroker or investment bank.
For an individual account, the required information includes identification details, a KRA PIN and other KYC information. CDSC's current account-opening form also requires a passport photograph.
Your basic checklist
- National ID, passport or other accepted identification
- KRA PIN
- Passport photograph(s)
- Completed CDS account-opening documentation
- Additional KYC information requested by your intermediary
CDSC also provides the Dosikaa digital route. Its current instructions say you can download the app, create an account, choose your preferred stockbroker and start buying shares.
3. Choose a licensed broker
Your broker is responsible for executing your NSE buy and sell orders.
The CMA's current stockbroker register lists firms including AIB-AXYS Africa, Faida Investment Bank, Genghis Capital, Kingdom Securities, Standard Investment Bank, Sterling Capital, NCBA Investment Bank, Dyer & Blair Investment Bank and SBG Securities, among others.
Always verify a broker's current licence before sending money.
When comparing brokers, consider:
- Brokerage charges
- Online or mobile trading facilities
- Customer support
- Minimum funding requirements
- Account statements
- Deposit and withdrawal arrangements
Don't choose a broker purely because its app looks good. Cost, regulation and reliability matter more.
4. Fund your account
Once your account has been approved, your broker will provide official instructions for funding it.
This is where you should be particularly careful.
Never send investment money to a personal number or an unofficial account simply because someone claims to represent a broker.
Use the payment details provided through the broker's official channels.
Also remember that the amount needed to open an account is not necessarily the amount needed to purchase a particular share.

5. Research before your first trade
Now comes the important question:
What are you actually going to buy?
Don't choose a share simply because somebody says it is among the best NSE stocks to buy.
Research:
- Company profits and revenue
- Dividend history
- Debt
- Share valuation
- Industry conditions
- Business growth prospects
- Trading liquidity
- Recent company announcements
The NSE provides market information and listed-company information that can help investors conduct their research.
Try this:
If a company's share price has increased by 30%, does that automatically mean you should buy it?
No.
You still need to determine whether the company's financial performance and future prospects justify the current valuation.
6. Place your first trade
Once you have selected a company, you submit an order through your broker's platform or other approved trading channel.
You will generally specify:
The company → the number of shares → the applicable order details.
For example, suppose you want 500 shares at KSh20 each.
Your basic trade value is:
500 × KSh20 = KSh10,000
But your final cost will include applicable transaction charges.
And there is another important point: placing an order does not guarantee immediate execution. Your order must be matched according to the market's trading and order-matching rules.
7. Understand the real cost
This is where new investors often underestimate what they need.
Your NSE trade can involve:
- Brokerage commission
- NSE transaction fee
- CMA levy
- CDSC levy
- Applicable investor compensation and guarantee-fund charges
CDSC currently publishes an equity transaction levy of 0.08% of equity turnover as one component of the charges associated with its services.
CMA's published fee schedule sets maximum charges for secondary equity trading. For transactions up to KSh100,000, the published maximum total cost is 2.10%. For transactions above KSh100,000, brokerage is negotiable subject to the applicable maximum and statutory charges.
Example
If you buy shares worth KSh10,000, a 2.10% maximum total cost would equal KSh210.
So the transaction could require approximately:
KSh10,000 + KSh210 = KSh10,210
This is an illustration using the published maximum, not a statement that every broker will charge exactly KSh210 on every transaction. Always request your broker's current fee schedule.
8. What happens after you buy?
Once your trade is completed and settled, the securities are reflected in your CDS account.
Your CDS account can hold securities from different companies, so you do not need a separate account for every share you purchase. CDSC also states that an investor can register a CDS account with more than one CDA while retaining the same CDS account number.
You can then monitor:
- Share prices
- Company announcements
- Financial results
- Dividends
- Your portfolio value
Remember that your portfolio value can change every trading day.
Your first NSE investment checklist

Alt text: Checklist infographic showing 9 steps to prepare for a first NSE investment before pressing "Buy."
Before pressing Buy, make sure you have:
☐ Identified your investment goal☐ Chosen a CMA-licensed intermediary☐ Opened a CDS account☐ Understood the broker's charges☐ Funded the account securely☐ Researched the company☐ Calculated the trade value and costs☐ Understood that prices can fluctuate☐ Kept your transaction records
So, how much do you need?
There is no single amount that every Kenyan needs to start investing in the NSE.
Your starting capital depends on the share price, number of shares you want, your broker's requirements and transaction costs.
You can therefore begin with an amount that fits your budget rather than assuming you need hundreds of thousands of shillings.
The key is to start informed, not simply because you can afford the minimum.
The bottom line
The basic route is simple:
Financial check → choose a licensed broker → open a CDS account → fund it → research a share → place your order → pay applicable costs → monitor your investment.
The technology has made NSE investing easier, but convenience should not replace research.
For current requirements, fees and licensed intermediaries, verify information directly with CMA and CDSC, because account requirements, charges and market arrangements can change.
