An investor buys a stock that will return $200 profit if it goes up today and lose $500 if it goes down. Based on the market trend, there is 70% chance that the stock will go up and 20% chance that it will go down and 10% chance it will stay the same. What is the expected amount of return

The expected amount of return can be estimated by adding the product of the potential outcomes and their probabilities or chances of their occurrence.

This can be calculated for this question as follows:

U = Profit when the stock goes up = $200

D = Profit when the stock goes down = $500

S = Profit when the stock stays the same = 0$

Uc = The chance or probability of the stock going up = 70%

Dc = The chance or probability of the stock going down = 20%

Sc = The chance or probability of the stock staying the same = 10%

Therefore, we have:

Expected amount of return = (U * Uc) + (D * Dc) + (S * Sc) = ($200 * 70%) + ($500 * 20%) + (0$ * 10%) = $140 + $100 + $0 = $240

Therefore, the expected amount of return is $240.
