portfolio of assets - diversification

Hey hopefully some of you can give me a couple quick tips regarding this uni assignment I have to do.

Question is:

You have been entrusted with monies for investment. Given current conditions on global markets what combination of assets would you combine together in a portfolio to ensure your portfolio is fully diversified? You may concentrate on any geographical location you wish. The dollar amount of investment is not important – what is essential is the percentage mix. Please justify your choice of assets and percentage allocations. (Hint: You should read about and try to understand current conditions on global financial markets to better answer this question. It is also acceptable to apply only bonds and stocks in your portfolio but if you wish to include other assets this is also acceptable). [1000 words]

Any tips greatly appreciated.

Cheers!!
