There will be no miracle. Less revenues from falling oil market will drag the index lower
as it should be around 800 already and could hit 530 when the oil would retest a multi-year low.
The correlation index for the past 12 months shows negative correlation but it is a temporary situation
as on the longer periods (20+ months) it is positive.
This will change gradually when the index will catch up with a falling "knife" oil.
