Definition
A Price-Weighted Index is a type of stock index where each stock contributes to the index value based on its price per share. In simple terms, the heavier (higher-priced) companies have a bigger say in the index compared to their cheaper counterparts, like how a tall person at a concert has a better view! Thus, higher-priced stocks will sway the index more than lower-priced stocks.

When a stock’s price goes up, it pulls the entire index along, making everyone a little giddier. Just remember, more dough means more clout!
