Episode notes
Complementary Trading And Research Partnership
- Scott Goodwin and Jonathan Lewinsohn combined trading and research skills to create a credit strategy that is greater than the sum of its parts.
- That complementary partnership enabled flexible long/short, across-credit investing and differentiated execution.
Invest Big Only With Conviction
- Build concentrated portfolios only when you have strong conviction and do deep upfront work before investing materially.
- Avoid toehold positions that make your portfolio diluted and average returns toward the mean.
From Law Clerk To Distressed Investor
- Lewinsohn transitioned from M&A and law to distressed investing after clerking for Judge Richard Posner.
- Anchorage gave him his first chance in distressed despite a nontraditional background.
