Stated strategy

Quantitative / systematic, Fundamental active, Value, Growth, Income, Fixed income / rates, Multi-asset, Long/short hedge Form ADV Part 2A, Oct 30, 2026 · original

In the firm's words

Quantitative / systematic: the team employs a combination of rigorous quantitative and fundamental research to evaluate securities that may offer compelling hedging opportunities.
Fundamental active: Co-portfolio managers, analysts, and traders work collaboratively to execute a fundamental, research-based bottom-up investment process.
Value: more stable companies (e.g., those that are effective stewards of capital with quality management) that are undervalued by the market but have a nearterm catalyst that we believe can move their security prices higher.
Growth: An equity strategy that seeks investments in small-capitalization companies that have sound growth potential.
Income: A strategy that seeks to pay high current income with the potential to deliver capital appreciation through investments in discounted closed-end funds that are believed to be positioned to benefit from narrowing discounts.
Fixed income / rates: For our fixed income portfolios, rigorous proprietary analysis drives fundamental security selection.
Multi-asset: Item 4 has been amended to include information about Asset Allocation Strategies that have been added to our Investment Services.
Long/short hedge: The long/short investment process is led by a macro top-down and fundamental bottom-up approach that seeks long and short opportunities in worldwide markets as well as in companies that exhibit enduring (on the long side) or eroding (on the short side) franchise value.

Portfolio style

Measured from the filed 13F common-share book for Jun 30, 2026, the newest measured quarter, never from the firm's own description.

Style

Diversified active

Top 10 weight 40.7%, 42.6 effective positions, active share 23.7% against the S&P 500 as of 2026-06-30; it meets none of the index-like, systematic-like or concentrated tests

Turnover

Low turnover

24.8% over the last four quarters (under 30%)

Horizon

Long horizon

Value-weighted holding period 20.6 quarters (12+), a floor since 72.9% of the book was already held when coverage starts

Closest benchmark: the S&P 500 as of 2026-06-30, active share 23.7%; sector active share 11.5% against the combined 13F book's sector weights.

Over time 26 measured quarters

How the bands are measured

Style bands measure the filed 13F common-share book each closed quarter, tested in this order. Unknown: under $10,000,000 of valued equity or 5 stocks. Index-like (100+ stocks): active share of 20% or less against the closest benchmark, which is the S&P 500, S&P MidCap 400, S&P SmallCap 600, Russell 1000, Russell 2000, Nasdaq-100 or Dow Jones Industrial Average (weighted by an index-tracking fund's reported holdings or the index's constituents nearest the quarter end, over the names resolved to companies, and only when those are 90%+ of its weight) or every 13F filer's combined book, or index series holding 80%+ of the registered fund assets it advises (N-CEN) and equal to 50%+ of its book. Systematic-like: 500+ stocks, 100%+ annual turnover and a top 10 weight of 25% or less. Concentrated: a top 10 weight of 60%+ or 12 or fewer effective positions. Diversified active: none of these. Turnover is the smaller of buys and sells over average equity value, summed over four quarters: low under 30%, high 100%+. Horizon is the value-weighted number of quarters each position has been held: short under 4, long 12+.

Covers the securities this platform tracks: U.S.-listed common stock and the put/call positions reported on it. A 13F can also report security types outside that coverage — preferred shares, bonds, warrants, untracked share classes — so the filing's own declared total can exceed the figures above. The source filing is linked at the top of this table.
