comment Analyzing an incomplete set of trades
It's actually an OTC market, so I know everything about the individual entities and can link them to their trades.

comment Market making in thinly traded assets
The lack of correlation is intrinsic to this asset. There simply aren't any other traded assets that have any measurable relation to its value (observed or otherwise).

comment Do I need a copula to accurately estimate the VaR of a portfolio of risky assets?
Thanks, one last question. You say that a Gaussian copula suffers the same tail risk problems as a multivariate normal, but what about a Gaussian copula with non-Gaussian marginals? Couldn't that fit fat tails?

Thanks for your reply, but if I were to use historical VaR on 20 assets (or even 6 as in your example), wouldn't it suffer from the curse of dimensionality? I thought that's why I needed to make distributional assumptions.

Well no model is perfect. I am aware of the criticism that people have put too much trust in VaR and gaussian copula, but that doesn't mean they have no use. What would you suggest instead?
