| Tiivistelmä: | This paper empirically examines economic benefits of giving investors (hereafter as: invts.) access to index options in the standard portfolio problem. Analyzed are both expected-utility and non-expected-utility invts. to understand who optimally buys and sells options. Using data on S&P 500 index options, it is always found optimal to short out-of-the-money puts and at-the-money straddles by constant relative risk aversion (CRRA) invts. etc. Loss-averse and disappointment-averse invts. optimally hold short option positions. Only with highly distorted probability assessments can positive portfolio weights for puts and straddles be obtained. |
