It's important to learn about stocks because it's one of the most common financial instruments that we can invest on or acquire to grow our money. Schools only teach the basic about stocks and bonds unless you are actually taking up a course that specializes in financial management. Such courses will usually cover not just theory but also immersion in investing or trading activities. If you want to learn stock and bonds more intensively, you can take MOOCs or watch YouTube videos on the topic. Many advise diving in and investing to learn the ropes. Remember, though, that investing doesn't always translate to earning. Stocks may be a liquid asset because they are easily convertible to cash but if you sell them at a price that is less than their acquisition price due to financial emergencies, then you have actually lost money.
Profitable investing in stocks on your own requires good knowledge and understanding of the market, industry, and the specific company share. If you are an employee who simply wants to invest money and enjoy some returns on it, it may be overwhelming to learn about stocks and bonds and the stock market. You may consider having your investment funds managed by professional money managers through mutual funds company or banks offering Unit Investment Trust Fund (UITF).
