It’s best if you can automate your actual stock investments. Robo-advisors can do this for you, or if you must, you can manually buy stocks every time you receive a paycheck and have money in your savings or brokerage account. The important point is that you make regular investments so that you aren’t tempted to time the market. Regularly investing the same amount is a form of dollar cost averaging, and it helps reduce risk in your stock investments.
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).

Brokers are either full-service or discount. Full-service brokers, as the name implies, give the full range of traditional brokerage services, including financial advice for retirement, healthcare and everything related to money. They usually only deal with higher-net-worth clients, and they can charge substantial fees, including a percent of your transactions, a percent of your assets they manage, and sometimes a yearly membership fee. It's common to see minimum account sizes of $25,000 and up at full-service brokerages. Still, traditional brokers justify their high fees by giving advice detailed to your needs.
Intuitive Surgical (NASDAQ:ISRG) -- Intuitive Surgical is a healthcare company that makes surgical robots and is the clear leader in the space. There are tens of thousands of doctors trained on the company's da Vinci surgical robots and more than 4,400 of the robots installed worldwide. As more surgical applications are found for the technology, these machines become more valuable to the hospitals that own and use them.
C (Fair) - In the trade-off between performance and risk, the stock has a track record which is about average. It is neither significantly better nor significantly worse than most other stocks. With some funds in this category, the total return may be better than average, but this can be misleading since the higher return was achieved with higher than average risk. With other funds, the risk may be lower than average, but the returns are also lower. In short, based on recent history, there is no particular advantage to investing in this fund.
Assess how much capital you're willing to risk on each trade. Many successful day traders risk less than 1% to 2% of their account per trade. If you have a $40,000 trading account and are willing to risk 0.5% of your capital on each trade, your maximum loss per trade is $200 (0.005 x $40,000). Set aside a surplus amount of funds you can trade with and you're prepared to lose. Remember, it may or may not happen.
A (Excellent) - The stock has an excellent track record for maximizing performance while minimizing risk, thus delivering the best possible combination of total return on investment and reduced volatility. It has made the most of the recent economic environment to maximize risk-adjusted returns compared to other stocks. While past performance is just an indication -- not a guarantee -- we believe this fund is among the most likely to deliver superior performance relative to risk in the future as well.
The use of borrowed money “levers” or exaggerates the result of price movement. Suppose the stock moves to $200 a share and you sell it. If you had used your own money exclusively, your return would be 100% on your investment [($20,000 -$10,000)/$10,000]. If you had borrowed $5,000 to buy the stock and sold at $200 per share, your return would be 300 % [(20,000-$5,000)/$5,000] after repaying the $5,000 loan and excluding the cost of interest paid to the broker.
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.
