Contact a Broker
The best starting point is to contact a stockbroker. You could, alternatively, have a conversation with a financial advisor or with someone who has experience and knowledge about the stock market. They will help determine the investment that bests suit you, but to actually own stock all roads lead to a stockbroker.
Get signed up
To get signed up complete a form, provide (2) two copies of national ID, a recent utility bill and a referral letter, usually from a bank. Companies have different requirements than an individual. Getting signed up is also necessary so your dividends can pass through the Trinidad and Tobago Central Depository (TTCD). This is when you will receive your own trading number.
The TTCD holds shares in an electronic form. Years ago, all shares were pieces of paper which, as you can imagine, could be easily misplaced. It also took a while to transfer shares from one investor to another if they were being traded. The electronic format makes it safer and faster. This means that getting dividends paid to you is now a lot easier.
