reported earnings volatility under different methods

Reported earnings is stated to have more volatility under the trading securities classification as opposed to the available for sale classification. is it right?

As i see it as the unrealized lossed go out of the OCI and get reported in the income statement at once ( under the available for sale method) the volatility increases because it is all reported at once.

Clarify please

AFS unrealized gains and losses bypass the income statement and go to OCI, hence less earnings volatility.
