many great points...
i'll just add that diversification is for the purpose of risks mitigation... to properly diversify, one needs to spread $ into various asset classes...not just within equities asset class...
if one has sufficient funds for investment, asset allocation is the macro form of diversifying one's risks...
so, money could be parked in properties, stocks, FCFDs, forex, running a business outfit, antiques, etc....
within each class;
eg property, one can further diversify with international purchases...1 in sgp, 1 in cambodia, 1 in aussieland, 1 in russia, whatever.... to mitigate risk of all properties in one single country (country risks)
eg, FCFD, one need to choose a few currencies instead of just USD or Euro
eg, as for stocks...as i mentioned, the simplest is to buy the sector ETFs, financial ETF will represent a group of financial companies....even if one collapses, the ETF would not be as hard hit as that single company....similarly, there's Oil ETF or Gold ETF, etc...buying a few of them is as diversified as one can get...
make sense?
