Understand the risks associated with the stocks you are investing in. In the company’s 10-K, there is an extensive section that talks about the company’s risks. You also need to understand your own tolerance for risk. If you invest in a stock that is highly volatile and you are not comfortable with market fluctuation, owning the investment will make you anxious and more likely to sell when it does not make sense strategically.
E (Very Weak) - The stock has significantly underperformed most other funds given the level of risk in its underlying investments, resulting in a very weak risk-adjusted performance. Thus, its investment strategy and/or management has done just the opposite of what was needed to maximize returns in the recent economic environment. While the risk-adjusted performance of any stock is subject to change, we believe this fund has proven to be a very bad investment in the recent past.
Define and write down the conditions under which you'll enter a position. "Buy during uptrend" isn't specific enough. Something like this is much more specific and also testable: "Buy when price breaks above the upper trendline of a triangle pattern, where the triangle was preceded by an uptrend (at least one higher swing high and higher swing low before the triangle formed) on the two-minute chart in the first two hours of the trading day."
Control greed – Greed often influences traders in the following way; you enter a trade at $80 with a target of $95, but then it hits $95 and you think ‘I’ll just hold on a bit longer and increase profits further’. This only ends with you eventually losing big. The solution; stick rigidly to your strategy. Think long term and don’t deviate from your strategy, there’s simply no need to gamble.
You’ll come across an overwhelming amount of information as you screen potential business partners. But it’s easier to home in on the right stuff when wearing a “business buyer” hat. You want to know how this company operates, its place in the overall industry, its competitors, its long-term prospects and whether it brings something new to the portfolio of businesses you already own.
