Trying reading up on Peter Lynch's: One up on wall street and Benjamin Graham's: The intelligent investor
On my end I follow the investing nature of Warren Buffett and Peter Lynch. Taking the stand of a long term investor.
(1) Invest only in companies that you KNOW. (eg. if I only know peanuts about the Oil industry, it wouldnt be wise for me to invest in it. However, I am extremelt well versed in IT technologies and what is going on etc, It makes more sense for me to invest in IT)
(2) Research on the company. (e.g the type of management they have, the people they have on their board, what is their company core business, are they constantly reinventing their products? or are they diversifying overly in other sectors that is not their core business?)
(3) I will ask myself this question, Do i foresee the company still NEEDED by the market? Do i foresee that the services of the company might become obsolete in the next 10 years etc. Leave the guessing to someone, i recommend you do the reading and research.
Theres more to this so do read up
*Invest only when you have spare cash.
*If you are looking to make a quick buck, I would suggest, please dont.
*Do not do shorting of stocks or borrow money to buy stocks, Ive seen a few go bankrupt due to speculations
