In a price-weighted index, stocks with higher prices receive a greater weight in the index, regardless of the issuing company's actual size or the number of shares outstanding. Accordingly, if one of the higher-priced stocks (Company D, in our example) has a huge price increase, the index is more likely to increase even if the other stocks in the index decline in value at the same time. In a price-weighted index such as the Dow Jones Industrial Average, NYSE Arca Major Market Index, and the NYSE Arca Tech 100 Index, the share price of each component stock is the only consideration when determining the value of the index. Thus, price movement of even a single security will heavily influence the value of the index even though the dollar shift is less significant in a relatively highly valued issue, and moreover ignoring the relative size of the company as a whole.
