Answer:
Investment in stock X is $6900 while that in stock Y is $3100.
Explanation:
The portfolio return is a function of the weighted average of the individual stock returns.
Let x be the weightage of stock X in the portfolio.
1-x is the weightage of stock Y in the portfolio.
0.1085 = x * 0.115 + (1-x) * 0.094
0.1085 = 0.115x + 0.094 - 0.094x
0.1085 -0.094 = 0.021x
0.0145 / 0.021 = x
x = 0.69047 or 69.047% rounded off to 69%.
(1-x) = 1 - 0.69 = 0.31 or 31%
Money invested in stock X = 0.69 * 10000 = $6900
Money invested in stock Y = 0.31 * 10000 = $3100
The amount that i will invest in X and Y is $6904.76 and $3095.24 respectively.
Let investment in X = $x
So, the investment in Y will be (10,000-x)
Portfolio return = Respective return*Respective weight
10.85 =(x/10,000*11.5) + (10,000-x) / 10,000*9.4
(10.85*10,000) = 11.5x + (10,000-x)*9.4
108500 = 11.5x + 94000 - 9.4x
x = (108500 - 94000) / (11.5-9.4)
x = $6904.76
Thus, the investment in X equals $6904.76.
Investment in Y = (10,000-x)
Investment in Y = (10,000 - 6904.76
Investment in Y = $3095.24
In conclusion, the amount that i will invest in X and Y is $6904.76 and $3095.24 respectively.
