Chen and Garcia next discuss characteristics of long–short and long-only investing. Garcia makes the following statements about investing with long–short and long-only managers:
Statement 1 A long–short portfolio allows for a gross exposure of 100%.
Statement 2 A long-only portfolio generally allows for greater investment capacity than other approaches, particularly when using strategies that focus on large-cap stocks. Which of Garcia’s statements regarding investing with long–short and longonly managers is correct?
选项:
A.Only Statement 1
Only Statement 2
Both Statement 1 and Statement 2
解释:
C is correct. Both Statement 1 and Statement 2 are correct.Statement 1 is correct because, similar to a long-only portfolio, a long–short portfolio can be structured to have a gross exposure of 100%. Gross exposure of the portfolio is calculated as the sum of the long positions and the absolute value of the short positions, expressed as percentages of the portfolio’s capital.
Gross exposure = Long positions + |Short positions|
Gross exposure long-only portfolio = 100% (Long positions) + 0% (Short positions) = 100%
Gross exposure long–short portfolio = 50% (Long positions) + |–50%| (Short positions) = 100%
Statement 2 is correct because long-only investing generally offers greater investment capacity than other approaches, particularly when using strategies that focus on large-cap stocks. For large institutional investors such as pension plans, there are no effective capacity constraints in terms of the total market cap available for long-only investing.
请问gross exposure =100%的构成,比如long70%,short30%,意思是做空数额占asset的30%,但是除了做多的asset的(即70%的资产),剩下的30%asset是作为现金在手上没有投资么(也就是说还有30%的asset可以去做多)?
