Just like gambling, the hot stock tip can create impulsive buying and can lead to trouble, that is unless you are financially able to loose your money. Running out to buy stock just because a friend claims to have made a lot of money is not a good enough reason. If a hot tip really is hot, then it will be worth adding to your portfolio and still be available even after you have taken time to do some research.
Every stock you buy really is a business and who would buy a business without looking into what it offers. Research needs to be done as to what the earnings are and what it actually sells. Learning about the company is just as important as knowing about the stock industry. Take time to compare similar stock in the same industry because if everyone from the mailman to your hairdresser is buying it, the stock price is probably inflated.
Cut your losses if your stock continues to loose value month after month because even the seasoned investor can make mistakes. Put your money into another area that has more hope of making money for you. No one should risk their hard earned money on a hot stock tip, no matter how good it sounds.
