Absolute Return funds are being offered by Putnam, Fidelity and other mutual fund organizations. The degree of freedom that most of these funds have is that they need not track to a particular index as a benchmark - such as the S&P 500. Instead, their goal is to assure you that you get positive returns for your investment over a 3-5 year period. The assurance that is given may be either a few percentage points above Treasury bill returns, or some other similar "safe" investment.
The methodologies that may be used however are frequently borrowed from how hedge-fund managers operate, thus giving the fund manager an opportunity to go long or short, or take on convertibles as securities and so forth.
It is also worthwhile contrasting absolute return funds against offerings from some Insurance companies with variable annuities who offer a minimum percentage of return but also set a ceiling on the maximum return in any given year. Of course insurance offerings usually come with load fees (frequently hidden away) and thus eat away at the returns through that mechanism.
Our suggestion has always been to either trust independent financial advisors or even better, independent newsletters with many years of experience behind them to guide you through the difficult times in the stock market.
