OCTA aims to balance growth potential with income generation by concentrating investments in the US energy sector. Portfolio selection is based on a value investment style, targeting mispriced companies using metrics like low price-to-forward-earnings (P/E) ratios, high free cash flow, strong balance sheets, a history of returning value to shareholders, and efficient operations in profitable drilling locations. The fund typically holds 30 companies, each deriving at least 50% of their gross income, net sales, or assets from energy-related industries. Companies primarily engaged in tar sands or oil sands extraction are excluded. No single position may exceed 5% at the time of purchase. The fund may also include ADRs from developed markets and can hold up to 20% of its assets in cash or cash equivalents.
