How stock prices change - And why they are almost impossible to predict?

Stock prices are like the ups and downs of a game where everyone is trying to guess what will happen next.

Imagine you're playing a guessing game with your friends in the park. You all have a bag of candies, and every time someone guesses the right color of the next candy, they get more candies, and so does everyone else! But if someone guesses wrong, they give up some of their candies. The number of candies each person has is like stock prices.

Sometimes you can see a pattern: red candies come in threes, blue ones in twos. But sometimes it’s random, like when the bag gets shaken really hard! That makes it almost impossible to know exactly what will happen next.

Even if you watch the game closely and know all the rules, your friend might suddenly shout, “I think purple is coming!” and everyone changes their minds. Stock prices work the same way: lots of people are guessing at once, and they can all change their minds quickly, like a sudden shake in the candy bag!
