The S-Curve

Welcome to The S-Curve

Now you will be able to receive the latest announcements, product updates, and our insights on the mortgage market in real time.

The name of the blog, the S-Curve, is a reflection of our logo and the central feature of our prepayment model. S-curves are seen in nature in many phenomenon, from population growth to prepayment and default models. Our first S-curve, in the early 1990s, used the arctangent function, then piece-wise linear functions, and evolved over time to be more complex and vary by FICO, loan size and LTV. This evolution encapsulates both the timeless nature of fundamental relationships and constant innovation to describe them better over time.

We hope you find the information useful and we look forward to your feedback.

    AD&Co Marketing Team

    News

    We proudly launched our new website on November 13th. As you familiarize yourself with the new look of ad-co.com, you will come to know the many new offerings we provide. Along with the new website, we have organized our products as a menu of models and applications for a wide range of investor appetites. Let us review the menu of our product offerings.

    Dynamic Models

    LoanDynamics (LDM) is the credit modeling solution you need. Our behavioral model helps you manage interest rate and credit risks in single family, multifamily, and auto loans by forecasting prepayments, delinquencies, defaults, and loss probabilities.

    RiskValDynamics (RVD) is our flexible valuation engine formerly known as OAS Subroutines. It combines LDM, our suite of MacroDynamics models, and our original, highly-efficient cash-flow engines.  

    MacroDynamics (MDM) is our suite of macroeconomic models including InterestRateDynamics, HomePriceDynamics, and UnemploymentDynamics.

    Applications 

    Kinetics is our new modular platform, designed to deliver the full suite of our models and analytics with the option to license only the tools you need. LoanKinetics , our multi-functional whole loan application, joins the Kinetics platform, along with MSRKinetics (MSRK), our new web-based offering focused on assessing MSR risk, and PoolKinetics, a module for pay-up valuation of agency pools.

    RiskProfiler (RP) is our complete valuation and risk assessment solution that covers all asset classes modeled by AD&Co: MBS and ARM pools, loans and their derivatives (IO, PO, MI, MSR), structured securities (CMOs), and hedge instruments. All inputs and outputs are stored in a SQL database.

    We hope the new interface helps you learn more about all that Andrew Davidson & Co., Inc. can offer during these unprecedented times.

    Thoughts

    The January 14, 2021 revisions of the Preferred Stock Purchase Agreements between the Treasury and the GSEs[i] (Government Sponsored Enterprises) along with the Treasury Department Blueprint on Next Steps for GSE[ii] Reform perhaps represent the end of a decade- long effort to create multiple competitive enterprises and end the government support of the GSEs.

    Martin Luther King, Jr. was a great leader and inspirational speaker. His wisdom can serve as a guide for as long as we remember him. Andrew Davidson & Co would like to acknowledge a fraction of what he gave us with two relevant quotes that seem fitting in 2021.

    Thoughts

    Separating signal from noise is at the heart of what we do at AD&Co. One of the key tools we utilize for that purpose is a sophisticated set of model performance trigger reports. These monthly reports not only alert us to model drift but also point to possible causes for the drift.
