Investing in private partnership structures such as hedge funds, private equity and private real estate can be a fruitful and exciting endeavor, especially when venturing into asset classes that lack competition and efficiency. An important qualification to remember when beginning due diligence on a partnership is that no investment is perfect. Each one has its own risks, however esoteric or idiosyncratic, and risks change over time, as do the operations and other intricacies of investment management.
