Do what one knows is best and to do it gladly. If you have to suffer through the misfortune of investing through one, give yourself the gift of learning everything you can about the markets, as well as your own temperament, biases and strengths. Choosing which stocks to invest requires effort, a disciplined and focused approach, and a dedication to learning your craft that's synonymous with learning any profession or trade. There's no secret ingredient when it comes to share trading - easy, overnight success is almost impossible to come by, and those setting their sights on short-term millions will be sorely disappointed. We can't predict what the market's going to do. We can only identify good companies trading for good values today.
The error that is made in stock investing analysis over and over again is that people look at the short-term and see what happens there and then presume that the same applies in the long term. This leads to all sorts of misunderstandings. There are always people who know what is going to happen before it happens and they either start selling or buying ahead of the event, or rumours are triggered and people in the loop take early positions. If enough people buy a stock, its price will go up (usually), due to the simple law of supply and demand. If enough people sell a stock, its price will go down. Learn to take small profits when you begin. Learn how to pick up those stocks that trades at a relatively low price and you will be on your way to a nice big trading account. Learn new ideas, keep up to date, and don’t trade other people’s ideas. Have a plan. When you’re an investor you are going to have trades that go against you. It happens to everyone. Don’t chase stocks. There will always be another trade right around the corner. The last thing you want to do is over-pay because you see a stock moving and think you are missing the boat. Always buy slowly when prices fall and sell quickly when targets are reached.
Be patient with your plan and think of it as a long-term voyage to a specific destination --- change direction infrequently and gradually. With a determination to learn and an eagerness to continue to learn your trade, what's stopping you from joining the best?
