Portfolio Choice Which portfolio would you prefer? No large differences across nations “The chart shows the high, low and most likely final values of £12,500 invested in 5 different portfolios for 5 years. For example, in Portfolio 1 you will get £13,500 and in Portfolio 5 you end up getting anything between £7,500 and £34,000, but the most likely amount is £19,000. Which portfolio would you prefer?”

Conclusions • Risk Perception not predictive • Except China – negative! • Returns Expectations are! • Especially when interacted with Risk Tolerance • Controlling for: • Risk Tolerance; • Risk Perception; • Returns Expectations; • Country-specific effects; • Only China maintains base-level difference in portfolio choice • Risk Tolerance always predictive • Singaporeans more sensitive
Social support network effects perceptions, not choices. Risk perception and social support Portfolio choice and social support "If things went wrong financially, I could rely upon the support of my family and friends." "If things went wrong financially, I could rely upon the support of my family and friends."
A progression of cultural differences A Similarity index (UK based) reveals an intuitive progression • The more mature the economy and market, the more it resembles the UK • The more dislike the UK, the higher the variance of its measurements • Indicates lack of stability in market expectations and understanding

Risk Tolerance Stable Over Time • 62% of the sample had no change in their allocated Risk Profile over 4 months • No changes of more than 1 Profile • The majority who changed were within 3 points of the profile boundary • The downturn in markets allowed us to test the scales market sensitivity • There was only a minor increase of 1.9% in the “Low” and “Medium-Low” Risk” profiles from June, 2007 Stability Good Risk Tolerance scales are also stable over time, and through market conditions. Risk Tolerance measurements may have some natural variance in them, but not a large amount Testing the Scale Our scales performed extremely well, being stable both across time and changing market conditions. This implies we were measuring a real underlying trait, rather than mood or sentiment Down One No Change Up One Immune to Market Conditions Low Med-Low Moderate Med-High High
