Getting the 'big picture' right is critical to your investment success. For example, ideally you would want to buy bonds when interest rates are high and sell when they are low. Conversely, you would want to be in shares when they are low and sell when they are high.
As always, you should consult your financial advisers, but do be sure they discuss overall asset allocation with you. There is far more money to be made in getting that right than in most individual investments.
