How to Buy Singapore Stock (4 Steps)

Open and deposit money into an online stock brokerage account if you do not already have one. If you have an account send in or set aside some money for your Singapore investment. To select a broker, a link to the 'Smart Money' magazine 2010 Broker Survey is provided in Resources.
Look up the current share price for the iShares MSCI Singapore Index ETF which has the stock symbol EWS. Use the quote screen of your online brokerage account, type in EWS, and select 'Get quote.'
Calculate the number of shares of EWS you want to buy. Divide your investment amount by the current EWS share price. Most brokers limit ETF trades to whole share purchases. Round your result to the nearest whole share.
Buy the shares of EWS using your brokerage account stock trade screen. You must enter the stock symbol 'EWS,' the number of shares you want to buy, select 'Buy to open,' and place the order. Your trade should be filled in a few seconds and the shares will show in your account summary.

How to Invest in Nigerian Stock

Decide whether you want to invest in individual stocks, ETFs (exchange-traded funds) or other indices. It is advisable for beginners in overseas investing to start by studying the different indices in the markets they are considering. These indices mirror the stocks in those markets. Examples include the Dow Jones Africa Titans 50 Index (DJAFK) and the Market Vectors Africa ETF (AFK). See links in Resources below for more on African ETFs and indices.
Pick an online brokerage based on your decision in Step 1. Investing in indices and ETFs will allow you more brokerages to choose from than if you pursue trading in individual Nigerian stocks. There are many online brokerage firms to choose from. They normally charge a monthly fee and between $3 and $20 for individual trades. For a fixed monthly fee, some will allow you to make automatic monthly investments for a specified number of trades with no minimum amounts.
Open a brokerage account that allows you to trade in Nigerian stocks directly if that is what you plan to do. Some brokerages may require that you submit a separate application to buy overseas stocks. Euro Pacific, for example, allows you to trade in overseas stocks directly. See a link to Euro Pacific in Resources below.
Use a Nigerian stockbroker. Contact the stock brokerage firms in Nigeria and closely follow the Nigerian market. See a link in Resources below to the Nigerian stock exchange for contact information for brokerage firms (also called issuing houses) authorized to trade stock in Nigeria.
Open your brokerage account and link it to your funding account. This allows you transfer the funds needed to begin investing.

How to Use Implied Volatility to Forecast Stock Price

Find a source for implied volatility information. Your online brokerage account will provide historic and implied volatility figures for any stock with options trading against the share price. Another volatility product is the Chicago Board Options Exchange Volatility Index, commonly called the VIX. The VIX can be easily charted and used to predict turning points in the overall market.
Compare the current level of implied volatility with the historic volatility for an individual stock. For the VIX, compare the current level to the average over the last six months to a year. You want to determine whether the current level of implied volatility is above or below historic levels and the magnitude of the departure from the norm.
Use the implied volatility deviations as signals for future stock price action. High implied volatility is usually a bearish signal, forecasting a pending decline in stock prices. Low volatility occurs when the market or stock prices are in an upward or bullish trend.
