Micro Cap Growth Commentary

December 31, 2009

The Driehaus Micro Cap Growth Composite (the “Strategy”) outperformed its benchmark, the Russell Microcap Growth Index (the “Benchmark”), by 342 basis points this quarter. The Strategy underperformed the Russell 2000 Growth Index (the “Index”) by 178 basis points during that same time period.

Key contributors to return for the fourth quarter included holdings in the Materials and Energy sectors. Performance for the quarter was constrained by stock selection in the Information Technology and Financials sectors. By the end of the fourth quarter, the Strategy maintained an overweight commitment to holdings in the Consumer Discretionary and Energy sectors and was underweight in exposure to the Health Care and Information Technology sectors relative to the Benchmark.

By quarter-end, the Information Technology sector represented the largest weighting in the Strategy. The Strategy increased its exposure to the Information Technology and Energy sectors over the quarter and exposure to the Health Care and Consumer Discretionary sectors were reduced.

During the quarter, the Strategy identified many interesting themes including: energy companies (specifically exploration and production (E&Ps) and service companies) benefitting from the strong growth in terms of new reserves and production (for E&Ps) and increased capital expenditures and drilling activity for select oil and gas service companies in the shale regions of the U.S.; technology companies, as the wireless Internet continues to be a powerful trend benefiting many companies in areas such as semiconductors, network equipment, security and software; financial companies (specifically regional banks) are an attractive area as many banks face improving credit trends, favorable net interest margins, and consolidation as healthy banks are often acquiring failed banks via FDIC brokered deals; and the auto sector is returning to health and many auto suppliers are well positioned for growth. Auto sales and production continue to improve from very depressed levels last year. At the same time, inventories remain very low and the restructured industry has, for the first time, removed major amounts of supply and capacity from the industry.
