Question

Consider the Black-Scholes-Merton model for two stocks:

dS1(t)=0.1S1(t)dt+0.2S1(t)dW1(t)

dS2(t)=0.05S2(t)dt+0.1S2(t)dW2(t)

Suppose the correlation between W1 and W2 is 0.4. Consider the dynamics of the ratio S1/S2, where A,B,C,D,F,G,I,J,K,L are constants to be found:

d(S1(t)/S2(t))=(ASB1(t)+C)SD2(t)dt+FSG1(t)SI2(t)dW1(t)+JSK1(t)SL2(t)dW2(t)

Hint: it may help to write down first the explicit expression for the ratio.

Answer 1

Please help me with this variation:

Consider the Black-Scholes-Merton model for two stocks:

dS1(t)=0.1S1(t)dt+0.2S1(t)dW1(t)
dS2(t)=0.05S2(t)dt+0.1S2(t)dW2(t)

Suppose the correlation between W1 and W2 is 0.4. Consider the dynamics of the ratio S2/S1, where A,B,C,D,F,G,I,J,K,L are constants to be found:

d(S2(t)/S1(t))=(AS1B(t)+C)S2D(t)dt+FS1G(t)S2I(t)dW1(t)+JS1K(t)S2L(t)dW2(t)
