Bridgewater Associates focuses on institutional portfolio management and consulting services in the global credit and currency markets. structures portfolios in a manner designed to produce consistent and uncorrelated returns. Bridgewater believes that building portfolios based on risk allocations is more effective than using capital allocations; and that investors should consider their strategic asset allocation (beta) separate from tactical moves (alpha). The firm believes investors can improve their portfolios' overall results by separately creating a well-diversified beta portfolio that is balanced against environmental biases and calibrated to one's targeted returns, and a well-diversified alpha portfolio that reduces systematic biases (and also calibrated to one's targeted returns). Bridgewater applies this approach to investing across the portfolios it manages. Bridgewater offers an active management strategy (\"Pure Alpha\"), a constrained active management strategy that invests in a subset of the markets in which Pure Alpha invests (\"Pure Alpha Major Markets\"), an asset allocation strategy (\"All Weather\"), and an investment strategy which applies its best understanding of how to combine All Weather with tailored active market views (\"Optimal Portfolio\").
