And if it crashes more, just keep buy more.. using the cost-averaging approach (i.e. slowly buying in as the market crashes, and slowly increasing the amount whenever there is another big crash, etc. and then pour it all in when there are signals that the market have stabilised).
View market crashes as a discount rather than a cause for panic.
