The best way to rebalance is to plough more money into the other areas until your asset allocation is back on track. How? Assuming your domestic equities now represent 45% of your asset allocation – but should actually be only 30% – stop sending money there temporarily and redistribute that 30% of your investment contribution evenly over the rest of your investment categories. You can do this by “pausing” your automatic investment to particular funds from within your investment account.
