Active Share (as of 9/30/19) Active Share is a measure of the percentage of holdings in a portfolio that differ from those of the benchmark. It is calculated by taking the sum of the absolute value of the differences of the weight of each holding in the portfolio versus the weight of each holding in the benchmark and dividing by two. Where the benchmark is the Russell 2000 Growth, the iShares Russell 2000 Growth ETF is used as a proxy. 86%

Performance data quoted represent past performance; past performance does not guarantee future results. The investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance of the Fund may be higher or lower than the performance quoted.

Rates of return for periods greater than one year are annualized.

Monthly Performance


We employ a risk-averse investment strategy predicated on the belief that strong long-term investment results are best achieved through a compounding of reasonable gains and the avoidance of major losses. We, therefore, consciously strive to limit downside exposure as much as to generate upside returns.

We focus on out-of-favor, undervalued situations with low P/E, P/B and P/FCF ratios and strong or rapidly improving cash flow dynamics. We seek to avoid fads and speculatively priced stocks, where the risk of mistakes is high.

We continually search for under-researched, growth situations that can be purchased for modest multiples. As such companies gain recognition and are accorded multiples more in line with their growth rates, we may become sellers. We also tend to focus on asset rich companies with improving earning prospects. In short we often follow the old saying, “Buy assets, sell earnings.” This tends to reduce the risk of earnings disappointments.

Underlying everything we do is an intense focus on cash flow, especially a company’s ability to generate free cash flow after all expenses and capital spending. Cash flow is more real than reported earnings, which are subject to accounting manipulation. Companies that generate strong free cash flow are able to repay debt, repurchase shares, and grow through acquisitions or reinvestment in their businesses. They are also attractive acquisition targets for both other companies and financial buyers. Because of these characteristics, companies with rising free cash flow are often better able to grow, regardless of stock market conditions and, at the same time, may offer downside protection during periods of market weakness.

Mutual fund investing involves risk. Principal loss is possible.

The Osterweis Fund may invest in medium and smaller sized companies, which involve additional risks such as limited liquidity and greater volatility. The Fund may invest in foreign and emerging market securities, which involve greater volatility and political, economic and currency risks and differences in accounting methods. These risks may increase for emerging markets. The Fund may invest in Master Limited Partnerships, which involve risk related to energy prices, demand and changes in tax code. The Fund may invest in debt securities that are un-rated or rated below investment grade. Lower-rated securities may present an increased possibility of default, price volatility or illiquidity compared to higher-rated securities. Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities.

While the fund is no-load, management fees and other expenses still apply. Please refer to the prospectus for more information.
