When to Sell a Stock: A Practical Guide for Individual Investors

Knowing when to buy a stock gets most of the attention in investing. But knowing when to sell a stock can be just as important to your long-term returns.

A stock rising 50%, 100% or even 300% does not automatically mean it is time to take profits. Likewise, a falling share price does not necessarily mean the investment has failed.

A better approach starts by remembering what a stock represents: ownership in an underlying business, rather than simply a ticker whose price moves every day. The framework in the attached analysis emphasizes that investors should reconsider a position primarily when their original investment thesis deteriorates or when valuation moves significantly ahead of realistic future growth.

For investors using Daba to invest in BRVM and NGX stocks, here is a practical framework.

How to Know When to Sell a Stock: Start With Your Investment Thesis

Before selling, return to the reason you bought the stock.

Perhaps you invested in an NGX stock because you expected earnings growth, expanding margins or stronger market share. Or maybe you bought a BRVM stock because of its dividend potential, competitive position or long-term growth prospects.

Ask yourself: Has anything fundamentally changed?

Consider a company such as Sonatel on the BRVM. If your original thesis is based on its telecommunications franchise, earnings generation and ability to distribute cash to shareholders, a temporary movement in the share price should not necessarily determine whether you sell.

The same principle could apply to Nigerian companies such as NASCON Allied Industries on the NGX. The attached analysis illustrates how NASCON’s share price increased substantially while earnings per share also expanded. Because earnings sometimes grew faster than the stock price, its valuation did not simply rise in line with the shares. An investor looking only at the price increase could therefore have exited too early.

The question is not simply, “How much has my stock gained?”

It is: “Does the reason I bought this business still hold?”

Stock Valuation and P/E Ratio: When Has a Stock Become Too Expensive?

One of the most useful tools for determining when to sell stocks is valuation.

The price-to-earnings ratio, or P/E ratio, compares a company’s share price with its earnings. A rising stock is not necessarily expensive if earnings are rising at a similar or faster rate.

For example, imagine an NGX company trading at ₦50 per share with ₦5 in earnings per share. Its P/E ratio is 10x.

If the stock rises to ₦100 but earnings increase to ₦7.50, its P/E becomes approximately 13.3x. The stock has doubled, but the underlying business has also grown significantly. That alone does not make it a sell.

BRVM investors can apply the same thinking when analysing companies such as Orange Côte d’Ivoire, Société Générale Côte d’Ivoire, Sonatel, or BOA Côte d’Ivoire.

Instead of asking whether the stock has risen “too much,” compare its valuation with its earnings growth, historical valuation, competitors, and future prospects.

Signs It May Be Time to Sell BRVM or NGX Stocks

Investors should monitor several fundamental warning signs.

A sale or partial reduction may deserve consideration when:

• The investment thesis has broken: The company’s competitive advantages or expected growth drivers have disappeared.
• Earnings quality deteriorates: Reported profits are growing but operating cash flow, margins, or returns on capital are weakening.
• Debt becomes excessive: Rising interest expenses or repeated fundraising can increase shareholder risk.
• Corporate governance deteriorates: Weak disclosures, questionable transactions, or poor treatment of minority shareholders may change the investment case.
• The valuation becomes unrealistic: The share price implies future growth that may be extremely difficult for the company to deliver.
• One stock becomes too large in your portfolio: A successful investment can eventually create excessive concentration risk.

The source framework specifically recommends examining cash flow, debt, margins, working capital and returns on capital rather than relying on headline profit alone.

Should You Sell a Stock After Making a Big Profit?

Not automatically.

This is especially important during strong periods for African stock markets, where individual BRVM or NGX stocks can appreciate significantly.

Selling simply because you fear losing an existing gain can lead you to exit high-quality businesses too early.

Instead, ask whether earnings and cash flows can continue growing and whether today’s valuation still offers an attractive expected return. The attached framework summarizes the principle well: price is useful information, but the decision should ultimately depend on expected return, risk and whether the original investment case remains intact.

Investing in BRVM and NGX Stocks With Daba

Investors can now use Daba to access stocks listed on both the BRVM and the Nigerian Exchange (NGX), making it easier to build and manage exposure across two of West Africa’s major equity markets.

Whether you own Sonatel, Orange Côte d’Ivoire, NASCON or another African company, successful investing requires looking beyond daily share-price movements.

Before pressing sell, ask three questions:

Has the business changed? Has the valuation changed? Has the expected return changed?

If the answers still support your original investment case, patience may sometimes be the better investment decision.
