| standaert | doesn't returns on all the stocks in the portfolio equal portfolio return? |
| Gina | vs the overall portfolio return |
| Gina | the way it is phrased it means each and every one stock... |
| danlan | IV is correct also, but it's not related to Roy's safety-first criterion. Right? |
| tssverma | Basically, it seems only portfolio is considered irrespective of how it is structured w.r.t. stocks. |
| kaliokale | I am sure i will be tricked if i see this question on the exam |
| mtcfa | to danlan: yes IV is correct and not related to Roy's safety first. It's just another way of evaluating an investment. |
| bobert | standaert, not necessarily. You need to consider the weight of the stock in the portfolio. |
| epizi | portfolio return is not similar to return on all the stocks.Some stocks will have better return that others but the portfolio records the aggregate return of all, and that is the reference of SF. |
| JKiro | standaert: portfolio components may include stocks, bonds and other assets such as commodities, real estate and cash... so we are interested in the "portfolio" return rather than simply "stocks" return |
| LionHero | Agree with JKiro |
| bundy | Portfolio vs all stocks SF Ration minimizes PORTFOLIO falling below threshhold |
| wenhu | really should read the question very carefully |
I used your notes and passed ... highly recommended!
