How to calculate stock weight in a real case
An engineer is teaching a small team live. He asks them to watch. He says we have two stocks. You own 50 shares of A at $20. You own 30 shares of B at $40. You want to know each stock share in the whole pile. He shows how to do it. He uses plain words and points at the screen.
Calculate the values step by step
- First know the formula. Stock weight = (shares × price) ÷ total portfolio value.
- Next find value of A. 50 × 20 = $1,000. Then find value of B. 30 × 40 = $1,200.
- Now find total. 1,000 + 1,200 = $2,200. Finally get weights. A weight = 1,000 ÷ 2,200 = 0.4545 → 45.45%. B weight = 1,200 ÷ 2,200 = 0.5455 → 54.55%.
