The most feared words on any stock exchange are margin call. A margin call is made when a position is losing money and more money is required by the broker to keep the trade open. If and when a stock ticker moves quickly, there can be people whose borrowing levels literally bankrupt them as things get worse ... fast. Volatility can be either a blessing or a curse, but if you have too much leverage, it can break a trader.
Depending on your goals, investing in individual stocks may be more trouble than it’s worth. Choosing index funds in a specific sector can provide your portfolio with the tilt you want, but with fewer dramatic swings. There are three criteria that can be leveraged to help guide fund choice. The most discussed is “expense ratio,” where lower means fewer fees to you. The second is the number of stocks in the fund. The higher the number, the more diverse the fund. Just as important is “total assets” under management. The more assets, the more other people also agree this is a great fund. When comparing two mutual funds, I’ll line up these three criteria for funds in the same category to make an informed decision.

Don't borrow money to use for stock market investment. On the stock exchange, borrowed money is known as either gearing or leverage. It is typically used either by companies (to help them finance growth), investment banks and hedge funds (to help juice their returns) or very aggressive traders. There are many spread betting (information here), options trading and day trading strategies that use borrowed money to enhance returns, but it also has a very profound impact on the risks being taken with each trade.
There are many fees an investor will incur when investing in mutual funds. One of the most important fees to consider is the management expense ratio (MER), which is charged by the management team each year, based on the number of assets in the fund. The MER ranges from 0.05% to 0.7% annually and varies depending on the type of fund. But the higher the MER, the more it impacts the fund's overall returns.
That’s because there are plenty of tools available to help you. One of the best is stock mutual funds, which are an easy and low-cost way for beginners to invest in the stock market. These funds are available within your 401(k), IRA or any taxable brokerage account. An S&P 500 fund, which effectively buys you small pieces of ownership in 500 of the largest U.S. companies, is a good place to start.
In that case, it is possible to invest passively in capital markets. This means that a private investor puts aside either a lump sum or an amount each month and the money is invested into a fund. That fund contains the savings of lots of other private investors and is managed by a professional equities investor. The fund will then be invested in an equity market (such as the NYSE) or a sector (such as energy).
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.
