All workflow is in the Blue Tractor cloud - effortless for the portfolio manager
Predictable, transparent subscription pricing scaled to ETF AUM
Active ETFs are expanding rapidly, driven by investor demand for innovative strategies that capture alpha.
But the standard fully transparent ETF structure exposes every holding and trade daily — turning your IP into an open book. Copycat and predatory traders – now armed with AI – can quickly unravel a portfolio manager’s strategy.
Traditional actively managed mutual funds never reveal portfolios daily — so why should an actively managed ETF?
Regulators worldwide have listened & now permit active strategies within a semi-transparent ETF structure — a solution that protects a portfolio manager’s edge while preserving all the benefits of the ETF wrapper.
Instead of full daily disclosure, semi-transparent ETFs publish a correlated tracking basket that shields portfolio IP, while still giving market makers the data they need to hedge risk and keep spreads tight.
Blue Tractor’s ETF tracking basket solutions are delivered by the Shielded Alpha® cloud service. Shielded
Alpha® is a family of semi-transparent ETF tracking baskets, ranging from an award-winning flagship
framework (developed for the U.S. ETF market, but applicable globally) to tailored, bespoke designs.
At their core, Shielded Alpha® tracking baskets deliver the optimal balance between:
Opacity for Asset Managers –safeguarding portfolio holdings and trading activity
Transparency for Market Makers –sufficient information to hedge risk and make effective
markets.
Regulators will pose the question: Does the semi-transparent ETF provide enough information for
market makers to ensure tight spreads and liquidity? Shielded Alpha® tracking baskets are designed
precisely to meet this test – optimized to give the capital markets what they need, while fully protecting
an asset manager’s edge.
Blue Tractor’s Shielded Alpha® cloud service powers a suite of semi-transparent ETF tracking basket solutions — from our award-winning flagship model, to bespoke baskets individually tailored to any portfolio manager’s strategy.
At their core, Shielded Alpha® tracking baskets deliver the optimal balance between:
Safeguarding portfolio holdings and trading activity
