Our Company History

South Street Capital Management (“SSCM”) is a capital manager specializing in residential Mortgage Backed Securities (“MBS”). SSCM was formed in 2018 as a partnership between Atlantic Capital Advisors (“AC Advisors”) and South Street Holdings Inc. who had been strategic partners for 10+ years.

AC Advisors had a long history of mortgage investing and mortgage banking. The management team at AC Advisors founded a privately held REIT in 1998 that remained its sole management duty until 2007 when they formed Hatteras Financial, which they took public in 2008. Original investment focus was in adjustable-rate and hybrid adjustable rate residential Mortgage Backed Securities (MBS). The strategy expanded from strictly ARMs to include agency fixed rate MBS, the creation of a whole loan conduit in 2013 and the purchase of an Mortgage Servicing Rrights (MSR) manager in 2015. Hatteras Financial was acquired in 2016 but the management team continued to manage the original privately held REIT.

South Street Securities Holdings Inc., through its wholly owned subsidiaries, is a leading provider of U.S. Treasury and Agency repo financing to Agency Mortgage REITs, asset managers, banks, broker-dealers and other capital market participants. South Street is a leading provider of MBS repo financing to the Agency REIT sector by acting as a credit intermediary between the Agency REITS and high-quality liquidity providers in the repo space. South Street’s mortgage business provides access to the capital markets for mortgage originators that hedge their forward pipeline exposure. South Street also provides other servicing, collateral management, technology, and administrative services for banks, broker-dealers and other capital market participants.

Our long history has allowed us to build strong relationships with non-bank mortgage originators, major commercial banks, leading investment banks, law firms and other asset managers.  We believe the model we execute appeals to the investor in search of investment stability and income. Our goal is to provide a diversification tool for asset allocation strategies to generate a higher risk-adjusted rate of return than traditional fixed-income alternatives.

As the nation’s largest donor- and volunteer-supported mentoring network, Big Brothers Big Sisters makes meaningful, monitored matches between adult volunteers (“Bigs”) and children (“Littles”), ages 6 through 18, in communities across the country. We develop positive relationships that have a direct and lasting effect on the lives of young people.

The First Tee

This initiative began as a way to bring golf to kids and teens that otherwise would not be exposed to the game and its positive values. What started as a concept to make golf more accessible to young people, turned into an opportunity to help ALL young people develop core values and learn life skills that are inherent to the game of golf. The First Tee Life Skills Experience was formulated with the help of academic, sport psychology, youth development and golf experts to proactively teach core values and life skills as part of basic golf instruction at chapters.
