Answer:
Total Stock price of Stock A = 156 x 45
Total Stock price of Stock A = $7,020
Total Stock price of Stock B = 130 x 30
Total Stock price of Stock B = $3,900
Hence, the total Stock price of Stock of A & B is $7,020 & $3,900 respectively.
Portfolio weight of Stock A = 7,020/ ( 7,020 + 3,900)
Portfolio weight of Stock A = 64%
Portfolio weight of Stock B = 3,900 / ( 7,020 + 3,900)
Portfolio weight of Stock B = 36%
Hence, the portfolio weight of stock A & B is 64% & 36% respectively.
