Alright, imagine you have a lemonade stand. Last year, your stand was not doing so well. You didn't make much money and your friends thought you should close it because it wasn't profitable.

But this year, something amazing happened! You started selling special types of lemonade that lots of people really love, especially grown-ups who use computers a lot for their work. Because of these new kinds of lemonade, more and more people came to your stand every day!

Now, at the end of this year, guess what? Your lemonade stand made way more money than ever before! You even have extra cash left over after paying all your costs. Plus, you have plans to make even better lemonades next year because some big companies want to buy from you.

So, your friends who thought you should close the stand are now really impressed and saying, "Wow, look at that successful lemonade stand! It's making so much money and people love it!" Some of them might even want to open their own stands now too!

That's what happened with SK Hynix. They made lots of new, special kinds of computer chips that many companies need for their work, especially the ones that use computers a lot to help them make decisions quickly (like we use our lemonades to think better!). Because these new chips were so popular, the company started making way more money than before.

Their friends who didn't believe in them are now saying nice things about SK Hynix and thinking they did a great job. The price of their stock (which is like a certificate you get when you buy part of the lemonade stand) also went up – it means many people think they'll continue to do well.

But even though everything seems great, some people at the stand are now looking a little sad because the stock's price went down a tiny bit that day. It happens sometimes, even if business is going really well. They're still super happy about their success and ready for next year! Read from source...
