I understand that of course currency and stock prices can change as a result of a multitude of factors, financial ones and socioeconomic ones.
But some computer program must change the numbers we see on the screen when we look up a stock price? They’re constantly changing so surely there are programs written to make those changes? But who is running those programs? How do they access news reports when there’s bad news and make the prices go down?
In: Economics
The stock prices are what the last trade of the stock occured at. This is reported by the exchange where the trade took place. When you look at the stock price, it is simply the last trade that was conducted.
The exchanges are companies that, well, what their business is, is running a stock exchange, you’ve probably heard of them, things like the NY Stock Exchange or NASDAQ or London Stock Exchange..
I’m not sure what you’re asking about “news”. Thats not relevant here. You’re just asking about how stock is traded and reported. The exchanges just make stock trades, they’re not news outlets
