Need n for time value of money calculations (see this linked slide) • Compounding frequency in a year = 360/90, so: m = 4.

The All Share Index is a market capitalisation weighted index, which means price movements of bigger companies have more importance. For example, a gain of 2% by PPC (JSE:PPC) on a given day means a lot more than, say, a 5% fall in the price of tiny brick maker Brikor (JSE:BIK). An index attempting to measure what the market is doing will obviously give more weight to PPC. Old fashioned stock market indices measured the change in the total market capitalisations of all shares on the market. Bigger market caps correctly had more influence. But a large number of companies are controlled outright, which means a large percentage of their shares never trade. Today's more sophisticated indices take account of that fact. Modern indices, such as the JSE/FTSE All Share Index, eliminate shares owned by founders, their families, directors and employee share schemes, also those locked up in strategic holdings or owned by government. They count only the "free float". Because of share price moves, every quarter some shares move into the Alsi 40 and others move out. While there are always 40 shares in the Alsi 40, those ranking from 35-40 are regarded as a buffer. To cater for new entrants, those ranking from 40-45 are kept in a reserve list. All those ranking above 35 at the end of a quarter are automatically included and those that fall below 46 are dropped. Those between 35 and 46 are the JSE's reserve list to allow for comings and goings. The indices are calculated every 15 seconds by computer. To that extent the indices are live and can be plotted minute by minute by intra-day traders. The indices have become more important in the past ten years as more and more investment funds track the market. On the grounds that it is difficult to beat the market, more and more funds simply "buy the market". They mirror various stock market indexes. A well-known local index tracker is Satrix. A company whose share price rises and finds itself suddenly in the Alsi 40, gets a second whammy as investment funds become obliged to buy its shares. A company that drops out will quickly experience selling pressure. The top 40 shares therefore trade at a premium. Which is all very nice for the companies and their managements - but it means it is difficult for an investor to find neglected bargains in the Alsi 40.
