Was a question on to calculate covariance between 2 markets. Completely had a brain fart on how to do this and where the formula is from?
M12 = (1.20 × 0.90 × 0.0225) + (0 × 0 × 0.0025) + [(1.20 × 0) + (0 × 0.90)] × 0.0022 = 0.0243.

Can anyone point it to me as to where I can reference this in the material/explain it.
