"Investing has become much easier," says Steve Sanders, executive vice president of marketing and new product development at Greenwich, Connecticut-based Interactive Brokers. "More of your hard-earned money will go straight toward your portfolio and not toward paying fees. I think this will be extremely helpful for beginning investors as well as others who like to save money."
Diversification allows you to recover from the loss of your total investment (20% of your portfolio) by gains of 10% in the two best companies (25% x 40%) and 4% in the remaining two companies (10% x 40%). Even though your overall portfolio value dropped by 6% (20% loss minus 14% gain), it is considerably better than having been invested solely in company E.
When investing in the stock market, you have to think long term and avoid the temptation to check your portfolio several times per day. All this will do is waste your time, stress you out, and increase the odds that you will make a big mistake and sell at the wrong time. Plan to set up automatic contributions to your investment so you can buy more investments no matter where you are.
When thinking about the mindset of investors, The Great Crash 1929 by J.K.Galbraith (reviewed here) should also be required reading. Typically, any sustained fall in prices - known as a bear market - is very destructive to wealth. However, as Galbraith explains wonderfully, each bear market is unique and is a reflection of the bull market that came before it. The book explains a great deal about the feedback loops that can exist when prices rise and fall as more people are either sucked into or forced out of holdings. It is the reference work about a very important slice of Wall Street history.
And you can find such stocks in lists like the IBD 50, Sector Leaders, IBD Big Cap 20 and IPO Leaders. For example, fast-growing semiconductor designer and artificial intelligence (AI) stock Nvidia was featured on the IBD 50 before it surged 750%. And Apple has been featured on various IBD lists as it has made big moves in recent years. While, of course, not every stock featured on an IBD list will make the type of moves that Nvidia and Apple have made, it does show why it pays to regularly update your list of stocks to watch using these S&P 500-beating screens.

You can buy stock directly using a brokerage account or app. Other options exist for those who are employed—either a 401k plan or a 403b plan if you work for a non-profit. Then there's the IRA—be it a Traditional IRA, Roth IRA, Simple IRA, or SEP-IRA account. You can also set up a direct stock purchase plan or dividend reinvestment plan (DRIP). Each type of account has different tax implications.
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.
