!hat is $basis risk%"

% Basis ris" describes the ris" that offsettin( investments in a hed(in( strate(y

$ill not e'perience cash flo$ or price (ains in the same manner5

% Basis ris" has the potential to create an e'cess (ain or loss and therefore is

not directional5 8he amount of basis ris" in a hed(in( strate(y describes theho$ much ris" is left behind due to imperfect correlation bet$een the t$o

investments5

% Basis ris" in subprime RMBS portfolios (enerally arises from

- &erformance differences in the underlyin( portfolio assets

- Structural differences in portfolio instruments

- 9i:uidity differences in the different secondary mar"ets

- 8imin( of e'pected cash flo$s from the portfolio instruments
