Suppose you won the lottery and had two options: (1) receiving $0.1 million or (2) taking a gamble in which, at the flip of a coin, you receive $0.2 million if a head comes up but receive zero if a tail comes up.
Suppose you won the lottery and had two options: (1) receiving $0.1 million or (2) taking a gamble in which, at the flip of a coin, you receive $0.2 million if a head comes up but receive zero if a tail comes up.
What is the expected value of the gamble? Round your answer to two decimal places.
Expected Value = Amount when Head * Probability of Head + Probability of tail * Cash flow when Tail
Expected Value = $0.2 Million * 50% + 50% * 0
Expected Value = $0.10 Million
Would you take the sure $0.1 million or the gamble?
Take $0.1 million
Because cash flow under both are equal so taking risk does not worth when you get same expected cash flow
If you chose the sure $0.1 million, would that indicate that you
are a risk averter or a risk seeker?
Risk averter
Suppose the payoff was actually $0.1 million - that was the only choice. You now face the choice of investing it in a U.S. Treasury bond that will return $108,000 at the end of a year or a common stock that has a 50-50 chance of being worthless or worth $240,000 at the end of the year.
The expected profit on the T-bond investment is $8,000. What is
the expected dollar profit on the stock investment? Round your
answer to two decimal places.
Expected Profit from Stock Investment = Amount when Worthy *
Probability + Probability * amount when Worth less - Investment
Expected Profit from Stock Investment = 240000 * 0.50 + 50% * 0 - 100000
Expected Profit from Stock Investment = $20000
The expected rate of return on the T-bond investment is 8%. What
is the expected rate of return on the stock investment? Round your
answer to two decimal places.
Expected Return on Stock Investment = Profit / Investment
Expected Return on Stock Investment = 20000 / 100000
Expected Return on Stock Investment = 20%
Would you invest in the bond or stock?
This depends on the individual's degree of risk
aversion
Exactly how large would the expected profit (or the expected rate of return) have to be on the stock investment to make you invest in the stock, given the 8% return on the bond?
0 because the stock is a risky asset but bond investment is a risk free asset. it depends on risk aversion of the investor to compute the return required from stock investment to make it comparable with bond
How might your decision be affected if, rather than buying one stock for $0.1 million, you could construct a portfolio consisting of 100 stocks with $1,000 invested in each? Each of these stocks has the same return characteristics as the one stock - that is, a 50-50 chance of being worth zero or $2,400 at year-end.
Investing in a portfolio of stocks would definitely be an improvement over investing in the single stock.
because correlation will help to reduce the risk of the portfolio
