About Us

A carefully planned trajectory

The name Convexity means a rounded curve joining two points on a graph. Convexity also represents the elegant arc of a business relationship formed by bringing together the smart eye for long-term investment with the craft of an excellent winemaker and Napa premier vineyards. Thus, Convexity represents the best investment — making classic, premium quality Napa Valley Cabernet.

The Team

Together John Meriwether, Chi-fu Huang and Eric Rosenfeld formed the LTWC. Earlier they were partners together in an asset management company, where they drew on mathematical models to make long horizon investments in equities, fixed income, and foreign currencies in the major global markets. LTWC continues this tradition of excellence in the more liquid markets.
