struggling asx

whats with our slack aussie stock market?
Recently when the dow drops 100-200 points we seem to follow suit the next day, shedding a similar percentage, but when the dow soars 100-200 points we don't seem to follow and stumble along gaining a handful of points the next day if we are lucky.
We seem to share their pessimism but not their optimism!
Ytd the dow has outperformed the asx too, i though our economy here was supposed to be booming
