One constant principle of investing is that markets fluctuate. Stock prices will rise and fall for a number of reasons: the economy, investor sentiment, political uncertainty at home or abroad, energy or weather problems, or even corporate scandals. This means market performance isn’t always predictable. That is why diversification, or spreading the investments in your portfolio among different asset classes and across different sectors within each class, is such an important strategy. Diversification is a time-tested way to manage risk.
Combat fear – Yesterday was a bad day, you lost over $1,500 and the fear is now kicking in, you’re being hesitant. That hesitation will cost you money, and as we mentioned above, you should embrace losses. When your confidence has had a knock, a useful tip is to remind yourself to stick religiously to your risk rules. If you have an effective risk management strategy you’ll never lose more than you can afford.

Because of the web today, all online brokers invest heavily into account security. SSL websites (look for “https” at the beginning any URL) are used by most brokers and some are now even offering two-factor authentication (using your phone to confirm a code before logging in). Just like shopping online and choosing a trustworthy website to purchase from, the best bet is to choose a well-known, established broker for your portfolio.


Leverage simply means the use of borrowed money to execute your stock market strategy. In a margin account, banks and brokerage firms can loan you money to buy stocks, usually 50% of the purchase value. In other words, if you wanted to buy 100 shares of a stock trading at $100 for a total cost of $10,000, your brokerage firm could loan you $5,000 to complete the purchase.
Successful traders have to move fast, but they don't have to think fast. Why? Because they've developed a trading strategy in advance, along with the discipline to stick to that strategy. It is important to follow your formula closely rather than try to chase profits. Don't let your emotions get the best of you and abandon your strategy. There's a mantra among day traders: "Plan your trade and trade your plan."
To make comparisons between companies, sectors and markets a little easier, there are a number of mathematical models used. The most common and often the most helpful is the P/E ratio. The Price to Earnings ratio takes the share price and is divided by the earnings per share. It is possible to calculate this using past earnings, projected future earnings and with all sorts of moving averages ;-) Therefore, this is one number that it is vital for any investor to know and understand.
A trading platform is software used for trading: opening, closing, and managing market positions through a financial intermediary such as an online broker. Online trading platforms are frequently offered by brokers either for free or at a discount rate in exchange for maintaining a funded account and/or making a specified number of trades per month. The best trading platforms offer a mix of robust features and low fees.
