If you have stocks in the stock market, it is always a good idea to watch it so you can see how your stocks are doing. Even if you do not, it is a good idea to watch it, because if you see something that is cheap and you think that it will result well, you might see one that you want to buy. I personally think that it is very smart to watch the stock market, because a lot of the time you can make millions for a low price. Hope this helps!
