1. Leave your emotions behind;
Emotional control is the most essential factor in playing the market. Never lose control of your emotions when the market moves against you. Don’t get too confident over your wins or too despondent over your losses
2. Never follow the crowd;
Be fearful when others are greedy, be greedy when others are fearful”
Oftentimes market hype is brought about by the media creating buzz around some financial news that were not yet thoroughly analyzed. At these moments, it is very hard not to jump on the bandwagon of overexcited traders and start buying stocks that everyone is talking about.
Later, when it turns out that this was nothing but a hype, you don't want to be one of those traders who are struggling with selling the stocks for close to nothing when the hype is over. The best example to illustrate Buffett's quote would be the notorious Dotcom crash that left countless number of traders with devalued stocks.
3. Trading is not only about graphs
Everyone would agree that investing involves much more than simply buying some stocks. Indeed, by entering the world of trading we involuntary delve into politics, economy, ecology and financial markets, learning more about what is going on in the world than we would ever expect.
But the trick is that it works the other way around just as well: the more you know about the world, the better you invest. That's why when you are thinking about making a new investment into a company, try to analyze their business as thorough as you can. The time you invest in this step will pay off later.
When analyzing a graph, never neglect the news section that goes together with it. Lots of important information can be hidden there.
