Markets are still dour today, as the federal government shutdown persists amid rising concerns about the debt ceiling, and the fact that there has been no movement toward a resolution on either issue. Some Republican lawmakers have been quoted  as saying that breaching the debt ceiling would not have deleterious effects on the economy -- which doesn't seem to indicate a sense of urgency in Washington to get the job done.

The Dow Jones Industrial Average (DJINDICES:^DJI), which has been sulky all day, took a dive about an hour before noon, but some components are shaking off the doldrums.

Winners soar
Procter & Gamble
(NYSE:PG) is a rising star today, as the company's annual meeting in Cincinnati kicks off. CEO A. G. Lafley has been filling investors' ears with sweet somethings, noting that even though P&G has met or exceeded its goals so far, it can do even better. Lafley also introduced some new performance metrics, such as "value creation" for both consumers and stockholders. Investors are loving it, and P&G is up 1.4% by noon.

Wal-Mart (NYSE:WMT) is also up more than 1.7% so far today. No doubt the big retailer is still glowing from its announced iPhone 5c price cut to $45, but a tasty deal with partner Krispy Kreme could also be giving the company a boost. The doughnut purveyor will soon be selling its own brand of ground coffee at select Sam's Club locations, which could be a boon for both Sam's Club parent Wal-Mart and Krispy Kreme.

Losers plunge
AT&T (NYSE:T) and Verizon (NYSE:VZ) go ex-dividend today, and both have dropped lower than might be expected from respective payouts of $0.45 per share  and $0.53 per share. Things may pick up as the day wears on, though. AT&T announced today that it plans to release a voice-over-LTE smartphone by year's end and expand upon that project next year. Meanwhile, Verizon reported earlier this morning that it has activated a new 4G LTE network in Watertown, N.Y. As lunchtime approached, there was a small improvement in these stocks, but the overall climate on the Dow is glum, at best.
