1) Volatility drives returns. The high volatility of 2008 led to large negative returns, but 2009 saw substantial positive returns as volatility decreased.

3) Looking back 3 years, only 4 of 15 asset classes had positive returns, with emerging markets and fixed income performing best. However, past performance does not predict future returns, and focusing only on past winners can be misleading.
