At 14:00 on a Tuesday in December, Barasa closed his M-Pesa till in Bungoma for a short break and placed an order for KES 1,500 of a US company. The app told him it would go through "when the market opens". Three and a half hours later, at 17:30 Kenyan time, it did. Barasa wanted to understand what he had just joined: what is the NYSE, and why does a market on the other side of the world decide when his money moves?
The New York Stock Exchange is the market where shares of many of the largest American and international companies are bought and sold. It does not set prices itself; it is the place where buyers and sellers meet, and the price is whatever they agree. Barasa's order, sent from a till in Bungoma, joined orders from buyers and sellers far beyond Kenya. The exchange's job is to match them and record each trade as it happens.
Here it is in plain words for a Kenyan reader, as part of our guide on how to buy US shares from Kenya, starting from one honest rule: prices can fall, and you can get back less than you put in. The sections below cover where the exchange came from, how a trade happens, and its hours in Kenyan time. Barasa's order is then followed from his till to the market, with the arithmetic shown.
A short history: from a street agreement to a global market
The NYSE traces its start to 17 May 1792, when 24 brokers in New York signed what is known as the Buttonwood Agreement. They agreed on a minimum commission and on dealing with each other first. The earliest trading was mostly in government bonds and a few bank shares. From those 24 brokers, it grew over more than two centuries into the exchange that Barasa's order reached.
Today the exchange sits at 18 Broad Street in Lower Manhattan, just off Wall Street, and is owned by Intercontinental Exchange, which bought it in 2013. Most trading is now electronic, though the famous trading floor still operates. It is among the largest stock exchanges in the world by the total value of the companies listed on it. For a Kenyan investor, the electronic side is what matters, because that is how an order from a phone reaches the market.
The NYSE is not the only big US exchange. The Nasdaq is another, home to many technology companies. Kenya has its own stock exchange in Nairobi, where shares are priced in shillings, while NYSE shares are priced in US dollars. That difference in currency is why the shilling's rate always matters when you own NYSE shares.
How buying and selling actually works
Every share you buy is sold by someone else, and every share you sell is bought by someone else. The exchange matches them. Three words describe how that matching works, and you will meet them on most trading screens. Knowing them helps you understand why the price you see is not always the price you get. Here they are:
- Bid: the highest price a buyer is offering right now.
- Ask: the lowest price a seller is willing to accept right now.
- Spread: the small gap between the two. When a buyer and a seller agree, a trade happens and that becomes the latest price.
Ordinary investors cannot trade on the exchange directly. Orders go through brokers, firms connected to the market, usually reached through an app. When Barasa pressed buy, his platform passed the order to its broker, which sent it to the market during trading hours. Each link in that chain is a firm you should be able to name before you send money.
Two common order types
A market order buys or sells at the best price available when the order reaches the market. It fills quickly, but the price can differ from the one you saw. A limit order sets the most you will pay or the least you will accept; it only fills at that price or better, and may not fill at all. Neither type protects you from a fall in the share after you buy. The choice is between speed and control over the price you pay.
NYSE hours in Kenyan time
Regular NYSE trading runs Monday to Friday, 9:30 in the morning to 4:00 in the afternoon New York time, and the exchange is shut on US public holidays. It also closes early on a few days, such as Christmas Eve. Kenya stays on East Africa Time all year, three hours ahead of UTC, but New York moves its clocks forward for summer from the second Sunday in March to the first Sunday in November. So the Kenyan hours shift twice a year. The table shows both periods:
| Period | Opens in Kenya | Closes in Kenya |
|---|---|---|
| New York summer time (mid March to early November) | 16:30 | 23:00 |
| New York winter time (early November to mid March) | 17:30 | 00:00 (midnight) |
In 2026, summer time ran from 8 March to 1 November, so from 2 November the market opens at 17:30 in Kenya. In 2027, summer time starts on 14 March. Orders placed outside these hours wait for the next session. Barasa's December order fell in the winter period, which is why it went through at 17:30 rather than 16:30.
Barasa's order, followed through
Barasa's company was quoted at $45.20 a share. To keep the example clear, assume a rate of KES 129 to the dollar, an invented figure, and leave fees out. These numbers show how a small order is converted and filled, and they are not a prediction of any price. Here is his order, step by step:
- One full share costs $45.20 × 129 = KES 5,830.80, more than he wanted to spend.
- His KES 1,500 converts to about $11.63, which buys about 0.2573 of a share.
- At the moment he looked, the bid was $45.18 and the ask $45.20. That 2 cent spread is about KES 2.58 per full share, a small cost built into every trade.
- His order was placed at 14:00 on a Tuesday in December, when the market was closed. It filled after the 17:30 opening, at the price then, which could have been higher or lower than $45.20.
Barasa learned two practical things. The price on his screen before the market opens is only the last price, not a promise. And for a long term holding, a few cents either way on the opening price matters far less than what the company does over years. Both lessons cost him little to learn, because the amount was small and his plan was long.
Why prices move, and the safety brakes
Prices move because buyers and sellers change their minds: a company reports profits or losses, the economy shifts, news breaks, or people simply become more hopeful or more fearful. A share can rise or fall a few percent in a normal day, and much more on a bad one. None of these causes can be predicted reliably, which is why the price of any share stays uncertain.
The US market has brakes for extreme days. If the broad market index falls 7% or 13% in a day, trading pauses for 15 minutes, unless it is late in the session; a 20% fall stops trading for the rest of the day. These pauses give people time to think. They do not stop prices from falling.
Past results do not promise future ones. Long histories of growth in the past have included years of heavy falls, and nobody knows what the next years hold. A long record tells you how a market has behaved, not how it will behave. Anyone who uses the NYSE's age or size as a reason to promise you a return is misusing its history.
Owning NYSE shares through Nyanyuka
Nyanyuka's Invest uses this same exchange. Once your savings reach KES 13,000, you can buy NYSE shares or parts of them from your savings, and Nyanyuka guides the choice and passes the order to its broker partner. Like Barasa's, an order sent while New York is closed waits for the next session and fills at the price then. So the hours in the table above apply to every order you place.
You decide what to buy and when to sell. Every share is priced in US dollars, so the shilling's rate matters alongside the share price, and prices can fall. The spread and the exchange rate both affect what you pay, exactly as in Barasa's example.

Frequently asked questions
What time does the NYSE open in Kenya?
It opens at 16:30 Kenyan time while New York is on summer time, from the second Sunday in March to the first Sunday in November. For the rest of the year it opens at 17:30. It closes at 23:00 in summer time and at midnight for the rest of the year. It is open Monday to Friday, except US public holidays.
Who owns the New York Stock Exchange?
The NYSE is owned by Intercontinental Exchange, a US company that bought it in 2013. The exchange itself traces its start to the Buttonwood Agreement of 1792. Its home today is 18 Broad Street in Lower Manhattan, just off Wall Street. Companies listed on it are owned by their own shareholders, not by the exchange.
Can I trade on the NYSE directly from Kenya?
No, individuals do not trade on the exchange directly; orders go through a broker, usually reached by an app or platform. Choose one whose licence and fees you have checked. Your order is filled during NYSE trading hours. An order sent while the market is closed waits for the next session, as Barasa's did.
Is the NYSE safer than other stock markets?
A large, long established exchange has clear rules, but that does not make any share on it safe. Prices of NYSE shares can fall sharply, and companies listed there can fail. Its safety brakes pause trading on extreme days, but they do not stop prices from falling. You can get back less than you put in.
In 1792, 24 brokers signed an agreement in New York that grew into the exchange where Barasa, an M-Pesa agent in Bungoma, now owns part of a share. How the market works, when it is open in Kenyan time, and what really happens after you press buy.
