3 terms

weighted average purchase price financial

"The price reported above reflects the weighted average purchase price"

The weighted average purchase price is the average cost per share you paid across multiple buys, calculated so larger purchases count more than smaller ones. Imagine buying apples at different prices: the overall price you effectively paid depends on how many apples you bought at each price. Investors use it to measure true cost basis, calculate gains or losses, decide when to sell, and manage taxes and portfolio performance.

contingent residual beneficiary technical

"a contingent residual beneficiary of the Rachel Lynn Shaw Trust"
