About Yayati

Broadening adoption of option-based strategies.

Yayati Asset Management builds the Guardrail portfolio family — strategies that use option collars to limit losses on stocks and bonds while preserving return potential. We pair institutional derivatives expertise with software that makes those strategies repeatable for advisors.

The problem we solve

Time savings

Pre-packaged derivative products are complex and tax-inefficient — they cost advisors time, not save it.

Customization

Outsourcing option strategies lacks scalability and carries high minimums.

Accessibility

Spreadsheet trading is manual and impossible to scale across a book of clients.

How the portfolios work

Risk management

Downside caps and option collars define the worst case before you enter.

Income generation

Covered-call writing turns volatility into a funded distribution.

Growth exposure

Capital-efficient structures keep upside participation intact.

Team

Institutional derivatives expertise.

Desks and product teams from Goldman Sachs, Deutsche Bank, Credit Suisse, Charles Schwab, and AssetMark — building option-based strategies advisors can actually run.
