The problem is that market-cap weighted indexes increase the amount they own of a particular company as that company's stock price increases. As a company's stock falls, its market capitalization falls and a market cap-weighted index will automatically own less of that company. Now to get the weights for each company, first add up the market capitalization for each company to get the total. Then take each company's market capitalization and divide it by the total to get its weight. For example, Company A's weight = \$100,000,000 / \$235,000,000 = 43%.
