Our Process

Our process rests on our firmwide commitment to uncovering and capitalizing on the persistent and recurring stock pricing inefficiencies in small-, mid-cap, and emerging-growth equities caused by a lag in investor response to new information. This lag in recognizing the catalysts likely to positively impact future earnings growth drives the security selection across all our strategies and mutual funds. The criteria used within each product, however, can differ. This is how our investment team implements our philosophy in the Concentrated Small-Cap Growth strategy.
