NO.PZ202105270100000404 问题如下 RicharMartin is chief investment officer for the TrunFountion (the fountion), whiha large, globally versifieinvestment portfolio. Martin meets with the fountion’s fixeincome anreestate portfolio managers to review expectereturn forecasts anpotentiinvestments, well to consir short-term mofications to asset weights within the totfunstrategic asset allocation. Martin asks the reestate portfolio manager to scuss the performancharacteristiof reestate. The reestate portfolio manager makes the following statements: Statement 1: Aing traREIT securities to equity portfolio shoulsubstantially improve the portfolio’s versification over the next year. Statement 2: TraREIT securities are more highly correlatewith rereestate anless highly correlatewith equities over multi-yehorizons. Martin looks over the long-run valuation metrithe manager is using for commercireestate, shown in Exhibit 1. The reestate teuses in-house mol for private reestate to estimate the true volatility of returns over time. The mol assumes ththe current observereturn equals the weighteaverage of the current true return anthe previous observereturn. Because the true return is not observable, the mol assumes a relationship between true returns anobservable REIT inx returns; therefore, it uses REIT inx returns proxies for both the unobservable current true return anthe previous observereturn.Martin asks the fixeincome portfolio manager to review the fountion’s bonportfolios. The existing aggregate bonportfolio is broay versifiein mestic aninternationvelopemarkets. The first segment of the portfolio to revieweis the mestic sovereign portfolio.
