You decide to invest $20,500 in Bank of America and $14,500 in Twitter. What is the portfolioâs beta? Bank of America beta: 1.27 Twitter beta: 1.96

Portfolio Beta = 1.555857143 rounded off to 1.56

Explanation:

The portfolio beta is the function of the weighted average of the individual stock betas that form up the portfolio. The formula to calculate the beta of a portfolio containing two stock is as follows,

Portfolio Beta = wA * Beta of A  +  wB * Beta of B

Where,

As the investment in Stock of Bank of America is 20500 and the investment in stock of Twitter is 14500, the total investment in the portfolio will be,

Total investment = 20500 + 14500  =  35000

Portfolio Beta = 20500 / 35000 * 1.27  +  14500 / 35000 * 1.96

Portfolio Beta = 1.555857143 rounded off to 1.56

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
