How To Trade Indices
Indices: The Trading Process
Index Volatility
Because indices include lots of various stocks, the volatility of an index can be very high, because of the unstopping movement of the share prices. In any case, for the same reason it is uncommon for indices to move by more than several percentage points per day, since it’s abnormal that all stocks on an index would encounter sharp developments within the same course at the same time. There are events, however, when this does happen; such examples are the crashes of the stock market crashes within the 20th and 21st centuries.
Indices Trading: An Example
The following situation, trader x chooses to take a position on the FTSE100. Suppose that the FTSE is currently trading at a level of 6949:6950, which means that the spread is one point at the moment. The trader chooses to ‘purchase’ £10 worth of the FTSE at the 6950 level. Since the ‘sell’ level is 6949, the trader starts off £10 down, since if the trader were to close this position quickly, that’s the loss they would experience.
Let’s suppose that the index along these lines rises to a level of 6955:6956. If the trader were to sell his £10 worth of FTSE at this moment, the profit on the trade would be £50; the first point of movement in the trader’s favor would turn their -£10 position into a £0 position (where they would be making neither a profit or a loss and would break even if they exited at this point), with the following five points of movement then being pure profit.
Still, let’s suppose that instead of the FTSE’s value going up, it goes down instead, to a level of 6945:6946. In this situation, the trader would lose £50 if they sold at that time, because the price at which that £10 worth of FTSE is being sold is five points lower than the price at which it was bought at.
