Sirius Trading Partners LLC

Sirius Trading Partners provides discretionary investment management for individual and high‑net‑worth clients through model-driven, ETF-based managed accounts. The firm offers two systematic mandates—one that rotates among traditional, unleveraged ETFs using daily momentum signals and one higher‑intensity multi‑horizon strategy that may employ leveraged, inverse, and volatility‑linked ETFs.

The firm’s investment process is quantitative and systematic, relying on proprietary models that use price momentum, volatility characteristics, and other statistical indicators to guide selection, allocation, and timing; portfolios may be concentrated, allocate to cash, and involve frequent trading including near the market close or in extended hours. Accounts are custodied at Interactive Brokers and managed on a discretionary basis, with ongoing monitoring and stated capacity limits to preserve execution efficiency.

Distinctive features in the brochure include published hypothetical and historical performance disclosures, which are uncommon among independent advisers and indicate the firm presents model backtests or track records alongside its strategy descriptions. Also notable for a small independent adviser is that the firm is not structured as a solo practitioner and explicitly documents different risk profiles and permitted instrument sets between its two mandates, along with procedures to limit new subscriptions when capacity constraints arise.
