An index was recently begun with the following two stocks:
Given that the value-weighted index was originally set at 100 and Company A's stock is currently selling for $4 per share while Company B’s stock is still at $10 per share, what is the current value of the price-weighted index and the market-cap-weighted index?
Price-weighted | Market-cap-weighted |
| ||||
| ||||
|
Price weight = [(4) + (10)] / 2 = 7 Market-cap weight = [(4)(50) + (10)(10)] / [(2)(50) + (10)(10)](100) = 150
