Stocks are holding on to this morning's gains, with the S&P 500 (S&P Indices: .INX) and the narrower, price-weighted Dow Jones Industrials Average (Dow Jones Indices: .DJI) up 0.22% and 0.31%, respectively, as of 1 p.m. EST. Within the Dow, winners outnumber losers by more than 2-to-1 right now. Let's go over the largest percentage losers of the day so far.
I see no immediate news item that would push shares of payment card issuer American Express Company (NYSE:AXP) down today, so I'm going to take this opportunity to offer a "longer-horizon" comment. In his latest annual letter to shareholders, released last Friday, Berkshire Hathaway Inc. (NYSE: BRK.A) CEO Warren Buffett praised American Express Company (NYSE:AXP) as one of his "Big Four" investments. Noting that the company's share repurchases had lifted Berkshire's stake from 13% to 13.7%, he added:
The earnings that the four companies retain are often used for repurchases -- which enhance our share of future earnings -- and also for funding business opportunities that are usually advantageous. Over time we expect substantially greater earnings from these four investees.
The bottom line for Mr. Buffett, which ought to be of great interest to Berkshire investors and value-oriented investors, is that "Berkshire's ownership interest in all four companies is likely to increase in the future." Let's be clear: That could be due to additional purchases by Berkshire or simply a result of continuing share buybacks by the company (or a combination of both). Either way, with American Express Company (NYSE:AXP) currently trading at 13.5 times the estimate for the next 12 months' earnings per share, it looks like Berkshire would receive adequate value for its dollar.
Shares of The Home Depot, Inc. (NYSE:HD) are also down today. Speaking of share buybacks, yesterday I pointed out that the home improvement retailer is one the top-five companies in terms of the size of its share buyback authorization as of the end of February. (In fact, it was No. 1, with a massive $17 billion authorization.) At a current valuation of nearly 20 times the estimate of the next 12 months' EPS, it's less clear, at first glance, that repurchases at current levels will create value equivalent to those of Amex's stock.
Finally, shares of energy supermajor Exxon Mobil Corporation (NYSE: XOM) are also losing ground today. Again, I can see nothing specific affecting the company, but the energy sector is mixed today. The market is like that most of the time -- it's best not to try to find an explanation for all of its gyrations.
