Stock Markets
The term 'Stock Market' is commonly used to encompass both the physical location for buying and selling stocks as well as the overall activity of the market within a certain country. When we hear an expression such as 'The stock market was down today' it refers to the combined activity of many stock exchanges i.e. the New York Stock Exchange (NYSE), Nasdaq etc. in the United States.

The 'Stock Exchange' is the correct term for the physical location for trading stocks. Each country may have many different stock exchanges and usually a particular company's stocks are traded on only one exchange, although large corporations may be listed in several different locations.

Stock exchanges exist throughout the world and it is possible to buy or sell stocks on any of them. The only restriction is the opening hours of each exchange. Both the NYSE and Nasdaq for example operate from 9:30 a.m. to 4:00 p.m. Eastern Time from Monday to Friday. Other exchanges have similar opening hours based on their local time. If you want to trade on the Hong Kong Stock Exchange your order will be executed sometime between 9:30 p.m. and 4:00 a.m. New York time.

The major stock exchanges of the world are located in Japan (Tokyo Stock Exchange), India (Bombay Stock Exchange), Europe (London Stock Exchange, Frankfurt Stock Exchange, SWX Swiss Exchange), the People's Republic of China (Shanghai Stock Exchange) and the United States. The major exchanges in the US are the NYSE, Nasdaq, and Amex.

Stock markets closely follow the economic health of a country. When the economy is doing well the market is bullish. Bull markets occur during times of high economic production, low unemployment and low inflation. Bear markets, on the other hand, follow downtrends in the economy. Inflation and unemployment are rising and stock prices are falling.

Fluctuations in stock prices are also driven by supply and demand, which in turn are determined to a large extent on investor psychology. Seeing a stock rise in price may cause investors to jump on the bandwagon and this rush to buy drives the price even faster. A falling price can have the same effect. These are short term fluctuations. Stock prices tend to normalize after such runs.

The stock exchange is only one of many opportunities to invest. Other popular markets include the Foreign Exchange Market (FOREX), the Futures Market, and the Options Market.

The FOREX is the biggest (in terms of value of trades) investment market in the world. FOREX traders buy one currency against another and can profit from small changes in value. Most FOREX trades are entered and exited in one 24 hour span, and traders have to keep a close watch on the market in order to make profitable trades.

The Futures Market is a market of contracts to buy and sell goods at specified prices and times. It exists because buyers and sellers of goods wish to lock in prices for future delivery, but market conditions can make the actual futures contract fluctuate considerably in value. Most investors in the futures market are not interested in the actual goods - only in the profit that can be realized in trading the contracts.

The Options Market is similar to the Futures Market in that an option is a contract that gives you the right (but not the obligation) to trade a stock at a certain price before a specified date. They can be traded on their own or purchased as a form of insurance against price fluctuations within a certain time frame.

All three of these markets are quite risky and require considerable knowledge and experience to prevent substantial losses. They also require close attention to market movements. Stocks, on the other hand, are less risky because movements of the market are usually gradual. Although short term investment strategies are possible, most view stocks as long term investments.

Stock Options
Stock options are contracts to buy (or sell) a stock at a certain price before a certain time in the future. Buyers of options have the right to buy the stock at the specified price, but they are not obligated to exercise their option. Sellers of options have the obligation to sell the underlying stock if the buyer of the option wishes to exercise it.

A contract to buy is called a 'call option'. The buyer of a call option hopes the price of the underlying stock will rise, allowing him to buy it at less than market value. The seller of the call option expects that the price of the stock will not rise, or at least is willing to accept a partial loss of profits made from selling the call option.

For example: An investor buys a call option on IBM with a 'strike price' (the price the stock can be bought) of $50. The current price of IBM stocks is $40 and the cost of the call is $5. If the price rises above $55 (strike price + cost of call) the buyer could exercise his right to buy and make a profit by reselling on the open market. The seller would still gain from the increase in price from $40 to $55 plus the $5 he made by selling the call. If the price remains below $55 the call would not be exercised and the seller would profit by $5 per share and the buyer would lose his $5 per share.

Options are traded on specific stocks. They detail the name of the stock, the strike price (the price the stock can be bought or sold at), the expiration date and the premium (the price of the option itself). After the expiration the option cannot be exercised and is worthless. Options have a value and are actively traded. An option to buy Microsoft, for example, is listed like this:

MSFT Jan06 22.50 Call at $2.00

This tells us that an option to buy 1 share of Microsoft at $22.50 before the third Friday in January 2006 can be bought for $2.00. Options usually expire on the third Friday of the specified month, and they are usually traded in lots of 100. To buy this particular option you would have to pay $200 (plus brokerage fees).

An option to sell a stock is called a 'put option'. This gives the holder the right (but not the obligation) to sell a particular stock within a certain time period at a certain price. In this situation the buyer is expecting the price of the stock to fall but does not want to sell outright in case the price rebounds. The seller feels that the price is stable or is willing to acquire the stock at the low price.

For example: An investor buys a put option on Microsoft with a 'strike price' (the price the stock can be sold) of $35. The current price of Microsoft is $40 and the cost of the put is $5. If the price falls below $30 (strike price + cost of put) the buyer could exercise his right to sell at a higher price than market. The seller would have to buy the stock at the higher-than-market price but any losses are offset by the $5 he made by selling the put. If the price remains above $30 the put would not be exercised and the seller would profit by $5 per share and the buyer would lose his $5 per share.

As can be seen, stock options can be used to protect against loss or as an investment opportunity in their own right. They are generally used as part of a trading strategy which combines the purchase of stock with the purchase of options.

For example, in a bull (rising) market you could buy stocks and call options and sell put options. This allows you to take full advantage of rising stock prices - the stocks you buy will rise in value, the call options will allow you to buy stock at less than market prices, and if the market dips and the buyer of your put option exercises it, you can pick up additional stocks at low prices. If the buyer does not exercise the option, you make money from the sale of the option.

Conversely, in a bear market, you can sell stocks, sell calls, and buy puts to limit losses and generate profits. Unstable markets can use a mixture of puts and calls to maximize profit potential.

Options are traded on Futures and Options Exchanges. There are 6 such exchanges in the United States including the American Stock Exchange (AMEX) and the Chicago Board Options Exchange (CBOE). In Europe the main options exchanges are Euronext.liffe and Eurex.
