(i) An index in general terms is a measure of relative change from one point in price to
another. Stock indices measure changes in price or value.
(ii) Drawbacks of NSE:
- 20 companies not true representatives
- Thinness of the market – small changes in the active stocks tend to be
considerably magnified in the index.
- 1966 base year too far in the past
- Relatively small price changes – some stock prices do not change for weeks on
end.
- Lack of clear portfolio selection criteria
- Use of arithmetic instead of preferred geometric mean in computing index.
- New companies have been quoted and others deregistered.
