weighted average price financial

"a weighted average price"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

profit sharing plan financial

"By profit sharing plan"

SSH trust financial

"As trustee of SSH trust for adult daughter"
