Hi, answer to your question can be explained by taking a numerical example. for example if price of the stock at the end of the period is \$20 as you have mentioned in your query and it was \$18 in the beginning of the period then there was a \$2 change in the price. therefore percentage price change will be \$20/\$18 (end of the period value/beginning of the period value) which is equal to 1.11% which is exactly same for a change of \$30 dollar in a stock of \$300 i.e \$300/\$270= 1.11% ( if stock price increased by \$30 to \$300). hence, equal weighted index only depends on the change in price irrespective of size of the company. equal weighted index is then calculated depending upon the change in price. in this example we can calculate the change in price by (1.11%+1.11%)/2= 1.11. if initial index value is 120. then equal weighted index value will be 120(1+0.111)= 133.32.
