Index construction

A Tilt is a rules-based portfolio: a set of construction rules and the constituents they produce. Tilt applies the rules to a universe of securities, ranks the securities that pass, sizes the positions, and returns the constituents. Each rebalance runs the same rules on fresh data. Publishing a Tilt through Tilt’s review process makes it an index. You can write the rules yourself or describe the Tilt to Tilt Agent, which writes them for you. You can read and edit every rule either way.

​

The construction pipeline

Each stage is a section on a Tilt’s Methodology tab: The result is the Tilt’s constituents: the selected securities and their weights on the evaluation date.

Find your way around

Select a Tilt in Library to open its Tilt view. In chat, select View details on a Tilt card or select a Tilt reference in a sent message to open the same view without losing your place in the chat.

1. Chats lists your conversations with Tilt Agent.
2. The conversation shows your requests and Tilt Agent’s replies.
3. The Tilt card summarizes a Tilt that Tilt Agent created or changed.
4. View details opens the Tilt view.
5. The message box takes your next request, such as a new Tilt or a change to its rules.

1. Close returns to the chat. A Tilt opened from Library shows Back to Library instead.
2. Methodology shows the rules and a backtest. Portfolio lists the constituents and weights.
3. The backtest compares the Tilt with a benchmark over a period you choose, with risk statistics.
4. The methodology sections hold the construction rules, one section per stage. Open a section and edit it. Each edit joins the change queue at the bottom of the Tilt view. Open the queue and select Apply to save the changes and re-evaluate the Tilt.
5. The actions menu has History, Export to Excel, and Publish to Marketplace.
6. History lists every methodology change, with who made it and when.

After opening a Tilt from Library, select Explore in chat and choose a suggested question or Ask anything. New Chat opens with an editable draft and the Tilt attached. Nothing is sent until you select Send. When you ask Tilt Agent for a change in the chat, it edits the same rules you see in the Tilt view.

A first example

This Tilt takes US companies worth more than $5 billion with strong free-cash-flow margins, ranks them by revenue growth and return on equity, and holds the top 20 by free-float market cap: market_cap is in millions of US dollars.
