Speculation in shares differs from investing. Speculation is cheap buying and expensive selling. As for investment, it is putting money and waiting for the financial return from distributing dividends, and that is monthly, quarterly, semi-annually, or annually.
Speculation is considered a great loss and I only recommend it to large investors who have sufficient experience on this subject. On the other hand, you can start investing, there are well-known companies, such as Facebook, Amazon, and others, you only have to wait for profits and sell shares when they increase by 20% or more.
