Investment Strategy
ACP aims to outperform the S&P 500 Index through stock selection based on intra-industry fundamental analysis, with a focus on intra-industry valuation methodologies. Primary research is a key component of their investment process. Their staff of portfolio managers and equity analysts track specific sectors within the Index, using stock valuation methodologies tailored to each sector and modified to reflect changing industry factors.
ACP's investments include long and over-weighted positions in attractively valued companies, both within and outside the Index, that are expected to outperform their peers. The portfolio also includes under-weighted and, in some cases, short positions in overvalued companies that are expected to underperform. A primary strategy is investing in undervalued securities, which carries financial risk but offers potential for capital appreciation.
