You can have the best strategy in the world, but if you can’t stay disciplined and keep your emotions in check, you risk losing profit. The first thing to note is that it’s human nature to show and react with emotion, especially when there’s money on the line. Fear, greed, and ambition are three of the most prevalent and potentially dangerous emotions. Fortunately, we have listed the top psychology tips to help you keep a level head.
The idea of perception is important, especially in investing. As you gain more knowledge about investments – for example, how stocks are bought and sold, how much volatility (price change) is usually present, and the difficulty or ease of liquidating an investment – you are likely to consider stock investments to have less risk than you thought before making your first purchase. As a consequence, your anxiety when investing is less intense, even though your risk tolerance remains unchanged because your perception of the risk has evolved.
P/E ratio -- The price-to-earnings ratio is the most widely cited valuation metric, and for good reason. It's an easy way to compare similar businesses. Simply divide a company's current share price by its last 12 months' worth of earnings. You can also use the projected earnings over the next 12 months to calculate the forward P/E ratio. The key point to know is that P/E ratios are most useful when comparing businesses in the same industry -- such as comparing ExxonMobil (NYSE:XOM) and Chevron (NYSE:CVX).
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 stock's market capitalization (cap) is its true value, the sum of the total shares multiplied by price. It has more meaning than the share price because it allows you to evaluate a company in the context of others of the same size in its industry. You can use a market cap as a filter to screen for companies to balance your portfolio. A small-cap company with stock capitalization of $250 million to $2 billion shouldn't be compared to a large cap, which ranges from $10 billion to $100 billion. Market capitalization influences your investment returns.

It is also worth trying to keep up to date with the latest thinking related to the area of investment that you are trying to specialise in. Therefore, if you plan to invest in defensive or income stocks, for example, it would be wise to read regularly about value investing and dividends. If you plan to invest in growth stocks, it would be wise to read about technology and the latest trends. Perhaps you could subscribe to one or more trade publications that relate to the sector(s) that you are most interested in.
A stock split is when a company increases its total shares and is frequently done on a 2-for-1 ratio. So, if you own 100 shares of a stock priced at $80 per share and worth $8,000, after the split you'll have 200 shares priced at $40 each, and still worth $8,000. Stock splits occur when prices are rising in a way perceived to deter smaller investors. They can keep the trading volume up by making it easier for a larger buying pool to trade. If you invest in a stock, expect to experience a stock split at some point.
