Alternative asset portfolio valuation involves assessing the worth of non-traditional investments such as private equity, real estate, hedge funds, collectables, and art. Unlike traditional investments like stocks and bonds, these assets often lack a transparent market price, making their valuation more complex. This process includes using various methods, such as discounted cash flow analysis, comparable sales, and appraisals, to determine the fair value of these assets. Accurate valuation is crucial for investors to make informed decisions, manage risks, and ensure the proper performance of their alternative investment portfolio.
