Given the size of your portfolio, I would not worry yet about diversification. Instead, concentrate on your best idea. Since you're into XOM at $86, I'd just keep buying this dip. It is one of the few values available right now among blue chips, and you can lower your average price per share by continuing to accumulate. By the time you are ready to retire, you'll want to have hundreds of shares of XOM, in addition to everything else you'll eventually have in your portfolio. So you might as well knock out the XOM part while the price is good!
