You're implicitly making a prediction here. Are you sure that the market will fall in the coming weeks?
Whether it's a week, a month, or a year, their market is going a lot lower yet. It'll retrace back to where it was, no matter what the central government does today. Trillions of dollars in real wealth will be lost in the debacle, as the event sets off dominoes.
As of now, if you invested the index four months ago, you haven't lost a penny.
