According to Bloomberg the index had climbed by more than 8% in October (until Thursday) and it's looking to finish higher still. All of the industry groups covered by the index are higher than they were at the end of September.
It'll even beat the surge seen in January, when the index rose by 7.2%. That was the best start to the year for the index since 1989.
The surge is partly down to some timely help from central bankers.
