During my appearance on the "Bulls & Bears" television show this weekend, I talked about Exxon Mobil ( XOM), and today I wanted to make sure the four or five of you who missed the show caught my remarks.

Specifically, I noted this stock should be a part of anyone's long-term portfolio.

Not surprisingly, I want you to forget about the fundamentals for a minute.

Instead, focus on the chart below, and you'll see a thing of beauty: 20 years of almost uninterrupted growth.

Sell, of course, when we stop driving cars.

Until then, Exxon Mobil is one of the few "buy-and-holds" I'd recommend keeping in everyone's portfolios.

Today, the Nasdaq, the Philadelphia Housing Index, Quidel ( QDEL), Motorola ( MOT), Quicksilver ( KWK) and Patterson-UTI Energy ( PTEN).

And that is the final word from Oahu, where (as usual) I am late to the party and only now catching the first season of "Lost" on DVD. Yeah, the show really is worth all the hype!

Please note that due to factors including low market capitalization and/or insufficient public float, we consider Quidel to be a small-cap stock. You should be aware that such stocks are subject to more risk than stocks of larger companies, including greater volatility, lower liquidity and less publicly available information, and that postings such as this one can have an effect on their stock prices.
