Money, AI, and a stock called NCB
A stock price is just a number that changes every day, like the temperature or the score in a cricket match. And anything that changes over time, you can try to predict with data. This week you will learn to forecast a real Jamaican stock, step by step, ending with a challenge worth real bragging rights.
Why would anyone predict a price?
Imagine you knew, even a little better than a coin flip, whether a price would go up or down tomorrow. You could decide when to buy and when to wait. That single skill, done carefully and well, is the engine behind an enormous amount of the world.
This is real, well-paid work, and it is wide open to anyone who can read data. You do not need a suit or a rich family. You need the skills in this course.
What is a stock, really?
Picture the most popular patty shop in Kingston. It is doing so well the owner wants to grow, so she splits ownership of the shop into a million tiny slices and sells some of them. Buy one slice and you own a real, tiny piece of the business. That slice is a share. The company is NCB; the shop is just easier to picture.
A share is part-ownership of a company. If the company does well, people will pay more for a slice, so the price rises. If it struggles, the price falls. The stock price is simply what people are willing to pay for one slice right now.
So a price is a tug-of-war. When more people want to buy than sell, the price gets pushed up. When more want to sell, it drops. News, profits, interest rates, and plain mood all pull on that rope every single day, which is exactly why the line in the chart above is so jumpy.
Meet NCB, on the real market
NCB Financial Group (its ticker symbol is NCBFG) is one of the largest companies on the Jamaica Stock Exchange. Its shares trade in Jamaican dollars, and the price moves every trading day. Here is what was actually true in mid-2026:
- Friday, July 10, 2026 close: J$74.50.
- One month earlier (June 15) it closed at J$52.50, so it climbed a lot in a few weeks.
- Its range over the past year ran from about J$27.50 to J$75.50.
Prices are real closing values from public Jamaica Stock Exchange data, mid-2026. Nothing here is financial advice; it is a teaching example.
A price is a "time series"
Look at the chart again. It is a list of numbers, one per day, in order. Anything shaped like that, one value per time step, is called a time series: daily temperatures, monthly rainfall, your weekly screen time. Predicting the future of a time series means guessing the next point from the points you already have. That is the whole game, and you will get better at it in every lesson.

- It moves by supply and demand: more buyers push it up, more sellers push it down.
- Prices form a time series: one value per day, in order.
- Predicting one is useful, real, and well paid, and this week you predict NCB.
