// Total Cost
Shares × buy price plus the buy commission — your full out-of-pocket investment.
// Annualized Return
Scales the holding-period return to a yearly equivalent so you can compare trades of different lengths.
// Break-even
The minimum sell price needed to fully recover your cost basis including both commissions.
