MSFT, C, XOM, JPM, GLD, GOOG, SDS, EWZ, EFA, and XLF.

Because these stocks and ETFs are so liquid (each security trades over $1B per day), they have an active options market, too. That results in smaller spreads on their options, which is good if you ever need to adjust a covered call position.

Volume should not be the only criteria you use when choosing investments. However, more liquidity never hurts and it can be used as one factor of many that you consider.
