Investing ₦50 Million or More in Nigerian Shares: Liquidity, Large Trades and Costs

At ₦50 million and above, buying Nigerian shares still means a licensed broker buying on the Nigerian Exchange (NGX), with the shares ending up in your CSCS account. What changes is the market side: whether a share trades enough for an order of that size to be filled, whether the order crosses the Exchange's large volume trade thresholds, how much the charges come to in naira, and what checks the broker makes on the money.

This guide covers those mechanics. It does not say what to buy or when. For the basics of opening an account and whose name the shares are held in, see our guide to investing ₦10 million.

Order Size Against Daily Traded Volume

The practical question at size is how your order compares with the number of shares that change hands on a normal day. Each share's daily volume is published in the NGX's daily market data. An order that is a small fraction of normal daily volume can usually be filled at prices close to those quoted. An order several times larger may take days to fill, and your own buying can move the price, within the Exchange's daily price limits.

Free float matters too. Where most of a company's shares are held by a parent company or a few large holders, fewer shares are available to trade, whatever the company's size.

• Ask your broker for the share's recent average daily volume before you size an order.
• A limit order sets the highest price you will pay; a market order does not.
• Expect partial fills on a large order. Each fill appears on a contract note.

The Exchange's Rules on Large Volume Trades

The NGX has specific rules for large trades in listed shares, in Part XIIIA of its rules for trading licence holders. Under the Rules on Large Volume Trades in Equities, a broker must apply for and obtain the Exchange's written approval before executing a trade that is:

• 5% or more, but less than 30%, of the company's total listed shares;
• 80 million units or more; or
• worth ₦800 million or more.

The broker applies with a copy of the client's mandate and the Exchange's authorisation form, and the Exchange responds within 24 hours of a complete application. Transfers of 30% or more, or that would change who controls a company, fall under separate block divestment rules. The broker makes the application; you provide the signed mandate.

At ₦50 million the value test is nowhere near reached; it starts at ₦800 million. The unit test can be. In a share priced at ₦0.50, ₦50 million buys 100 million units, which is above 80 million. NGX Regulation has also published proposals to tighten these rules, so ask your broker which version applies on the day.

Negotiated Trades

Sometimes a buyer and a seller agree a price and quantity for a block of shares in advance, through their brokers. This is sometimes called a negotiated or cross deal. It still goes through licensed brokers and is executed on the Exchange's trading system. Where such a trade crosses the large volume thresholds and is priced away from the prevailing market price, the broker must give the Exchange the basis on which the price was calculated before submitting the trade.

These trades are mostly arranged for institutions and very large holders. If you are offered a block of shares privately, outside a broker, be very careful: a genuine trade in listed shares is executed through a licensed broker and settles through the CSCS.

Settlement and Paying In

NGX trades settle one business day after the trade date (T+1), a cycle that began on 1 June 2026. The money has to be with the broker in time for that. Transfers of this size can run into your bank's daily limits, so arrange them with the bank in advance. Paying from a Nigerian bank account in your own name keeps the record simple.

Source of Funds and the Checks at Size

The SEC's anti-money laundering regulations for capital market operators require brokers to record the source of the funds, how a payment was made, from where and by whom. For higher-risk clients, products or accounts, they must take further steps to establish the source of wealth and funds. Politically exposed persons need senior management approval before an account is opened.

In practice, a large payment is likely to prompt questions. Evidence such as a property sale agreement, business accounts, an employer's letter or estate papers answers them faster than an explanation after the event. Have it ready before you pay in.

What It Costs at Size

Every trade carries the broker's commission and the regulatory charges set for the Nigerian market, and whoever you buy through adds their own charge. Percentage charges grow in step with the amount, so compare in naira. At Shares Saver the fee is ₦1,500 plus 0.4% of each purchase, with nothing charged month to month on what you hold:

• ₦50 million: ₦201,500.
• ₦100 million: ₦401,500.
• ₦250 million: ₦1,001,500.

The broker's charge applies on top, and every charge is shown before you confirm. Splitting a purchase adds a flat fee each time: ten purchases of ₦10 million cost ₦415,000 in Shares Saver fees, against ₦401,500 for one purchase of ₦100 million.

Spreading Purchases: The Mechanics

Large sums are often invested in several purchases, for mechanical reasons: an order in a thinly traded share may take several days to fill anyway, and money may arrive in stages. Splitting an order is not a way around the large volume rules: the Exchange has said that some market participants structure trades to get around them, and has proposed tighter rules in response. Splitting also does not remove price risk, because prices can move either way between purchases. Shares Saver does not advise on timing.

Records Worth Keeping at This Size

• A contract note for every fill, not just every order.
• Your CSCS statement, checked against the contract notes after each purchase.
• Evidence of where each payment came from, kept with the payment record.
• Any correspondence about approvals or negotiated trades.

Frequently Asked Questions

Do I need the Exchange's approval to buy ₦50 million of shares?

Not because of the value alone, as the value threshold is ₦800 million. Approval is needed if the order is 80 million units or more, or 5% or more of the company. The broker applies; you sign the mandate.

Can I buy a block of shares directly from another shareholder?

A price and quantity can be agreed in advance, but the trade itself goes through licensed brokers on the Exchange and settles through the CSCS.

How long does a large order take to fill?

It depends on how much the share trades. An order small beside daily volume may fill the same day; a large order in a thinly traded share can take several days.

Will anyone tell me what to buy?

Not at Shares Saver: we do not give investment advice. An independent, SEC-registered adviser can help you decide.
