Answer:
Equity increases by $20,000 an SMA by $10,000
Explanation:
While equity is defined as the remaining value of an owner's interest in a business , the simple moving average is defined as the average of a selected range of prices , usually the closing prices by the number of periods in that range.
For every $1 increase in market value , the SMA increase by $0.5 and the equity by $1
Workings
1000 shares at $30 = $30,000
Market value = 1000* $50 = $50,000
Equity increase - 50,000-30,000 = 20,000
SMA = 20,000 *0.5 = 10,000
