Factors Affecting Performance [Text Block]
How did the fund perform over the last six months?*

For the period of January 1, 2025 to June 30, 2025, the fund returned 1.20%, underperforming the fund's broad-based securities market index, the Bloomberg U.S. Aggregate Bond Index, which returned 4.02% for the same period and underperforming the fund's secondary index, the Bloomberg U.S. Treasury 30 Year Bellwether Index, which returned 2.11% for the same period.

What factors materially affected the fund's performance over the last six months?

Despite volatility during the period, yields of long-term Treasury bonds ended the period relatively unchanged. The treasury bond market exhibited volatility throughout the period in response to tariff concerns and shifts in expectations regarding Federal Reserve policy decisions. Uncertainty about the long-term economic impacts of tariffs and fiscal policy have led to the volatility in long term treasury yields over the period. Long-term treasury yields reached their lows in April 2025 before rising steadily through the end of the period and ended the first half of the year mostly unchanged.

How did the fund perform over the last six months?*

For the period of January 1, 2025 to June 30, 2025, the fund returned 5.86%, outperforming the fund's broad-based securities market index, the Bloomberg U.S. Aggregate Bond Index, which returned 4.02% for the same period and outperforming the fund's secondary index, the Bloomberg U.S. Corporate High Yield Index, which returned 4.57% for the same period.

What factors materially affected the fund's performance over the last six months?

High yield continued to generate positive returns for the reporting period. During the period, risk assets experienced some volatility due to macro-economic factors stemming from trade negotiations and tariffs. After the initial market shock of increased tariffs on trading partners, risk assets rebounded and continued to generate positive total returns. All sectors contributed positively to the Bloomberg U.S. Corporate High Yield Index (the "Index") with notable positive contribution from communications and consumer discretionary. On the ratings side, BB-rated holdings led contribution to returns of the Index.

How did the fund perform over the last six months?*

For the period of January 1, 2025 to June 30, 2025, the fund returned -3.99%, underperforming the fund's broad-based securities market index, the S&P 500 Index, which returned 6.20% for the same period and underperforming the fund's secondary index, the ICE BofA 3-Month U.S. Treasury Bill Index, which returned 2.09% for the same period.

What factors materially affected the fund's performance over the last six months?

In the first half of 2025, futures markets were marked by a mix of reversals and consolidation, presenting a challenging environment for trend-following systems. Global stock index futures saw choppy behavior, with early-year rallies in U.S. and European equities stalling amid shifting central bank policy signals and geopolitical uncertainty. Bond futures were volatile but lacked sustained directional moves, as inflation data and diverging rate expectations kept global yields in flux. In foreign exchange, the U.S. dollar strengthened modestly against major currencies in Q1 before weakening in Q2, driven by changing interest rate differentials and mixed economic signals across regions. Commodity futures were mixed—energy markets, particularly crude oil, saw sharp but short-lived moves tied to supply disruptions and OPEC policy, while metals and agricultural contracts experienced sporadic price swings without sustained trends.

This backdrop of frequent reversals and limited trend persistence across asset classes created a difficult environment for trend-following models, which typically perform best in sustained directional markets. Reflecting these conditions, the fund posted a negative return in Q1, with losses across all asset classes—Currencies and Fixed Income were the largest detractors, while Commodities and Equities also contributed to the decline. In Q2, performance improved, supported by gains in Commodities, Currencies, and Equities, though Fixed Income remained a drag. Despite the recovery in Q2, the fund ended the first half of the year with a net loss.

How did the fund perform over the last six months?*

For the period of January 1, 2025 to June 30, 2025, the fund returned -2.10%, underperforming the fund's broad-based securities market index, the S&P 500 Index, which returned 6.20% for the same period and underperforming the fund's secondary index, the HFRX Global Hedge Fund Index, which returned 2.38% for the same period.

What factors materially affected the fund's performance over the last six months?

The fund's merger arbitrage strategy was the largest positive contributor in the first half of the year as several notable deals closed (e.g. Capital One / Discover). Closed-end fund arbitrage and the long/short equity strategy also made modest positive contributions. The fund's global macro strategies were a net detractor during the period as positive contributions from Flow (driven primarily by fixed income) did not make up for poor performance in value (primarily commodities and fixed income) and Momentum (hurt by equities and currency). Flow strategies take positions based on expected capital flows in markets which are determined through economic theory or statistical observation of market behavior. Momentum is a systematic trend-following strategy that seeks to capture momentum premia in futures markets. Carry strategies seek to capture inefficiencies in the futures curves of different markets and asset classes including commodities, fixed income, and implied volatility. Value premia strategies take positions based on expected future prices in markets as derived from economic and/or non-price data and include strategies applied to commodities, currencies, and fixed income. A market neutral strategy attempts to profit whether the market is going up or down.

How did the fund perform over the last six months?*

For the period of January 1, 2025 to June 30, 2025, the fund returned 1.43%.

What factors materially affected the fund's performance over the last six months?

For the first half of 2025, resilient economic data delayed the timing of expected rate cuts and inflation remained slightly above the U.S. Federal Reserve's (the "Fed") target level. At its June 2025 meeting, the Fed noted that economic activity continued to expand at a solid pace, the labor market is solid and inflation remains somewhat elevated. Uncertainty about the economic impacts of tariffs and fiscal policy has resulted in the market pricing in two 25 basis point rate cuts for the remainder of 2025.
