Yep, that's what I said -- that you can easily get additional risk by not diversifying.

And the trading fees are outside of EMH -- there are certainly plenty of ways to reliably lose money in the real world, but not in the EMH world.

I said 'uncompensated' risk.

EMH doesn't say anything about uncompensated risks.

To get to risk premium you need something like CAPM or APT which are a different kettle of fish.
