The Intelligent Investor by Ben Graham ought to be required reading for every private investor. While the innovations he brought to stock analysis have long been outdated and the red flags he used to watch out for in a company's accounts are now regulated against by the SEC, many of his insights about thinking about investment still stand. For example, his description of Mr Market is still an excellent way of understanding how a crowd moves with the daily news.
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.
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.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.
