BALTIMORE (Stockpickr) -- The dividend increases continued last week despite the uptick in market volatility that sent the S&P 500 tumbling nearly 2.17% by last Friday's close. All told, 27 companies increased their payouts to shareholders, cementing what's already been a strong quarter for increased dividend outlays.

Those dividend numbers are especially important as volatility increases. That's because dividends are largely immune from market sentiment shifts that border on irrational.

Even during times when stock prices slide, as long as companies are seeing continued fundamental performance, dividend stocks can deliver income to your portfolio. Historically, though, dividend stocks also beat non-payers by a large clip on price appreciation.

That's because over the last 36 years, dividend stocks outperformed the rest of the

S&P 500

by 2.5% annually, and they outperformed nonpayers by nearly 8% every year, all while paying out cash to their shareholders, according to a study from NDR. And right now, companies that are willing to part with cash in arguably tough times are worth a second look.

Despite a semiconductor slow-down that's affected the entire industry,

Intel

(INTC) - Get Report

has had an active year thanks to its acquisition of McAffee for $7.7 billion earlier this year, and now a sizable dividend increase.

Intel's utter domination of the semiconductor industry has made this stock a popular option for investors looking for exposure to the mature end of the tech sector. In total, Intel lays claim to nearly 75% of the chip market, and has the financial wherewithal to pour substantial cash into its research and development projects.

Of course, another area where Intel is putting resources is its dividend payout. Last week, the company increased its quarterly payout by 14.3%, bringing its total dividend to 18 cents per share.

and

General Electric

(GE) - Get Report

Automatic Data Processing

(ADP) - Get Report

is another company that's enjoying increased shareholder attention at the hands of a dividend hike. Last week, the human resources administration giant increased its dividend to 35 cents per share, a 5.9% raise for the stock's owners.High switching costs have helped make this firm less prone to turnover rates as clients seek out cheaper servicers. Instead, it's the number of employees on clients' payrolls that's been threatening to curb growth at ADP.

If any stock is susceptible to overall economic trends, it's ADP. As one of the nation's biggest payroll and HR servicers, the company's top-line is driven directly by employment levels at its more than half-million client firms.

Regardless of unemployment woes, ADP has continually managed to improve its numbers and expand its service offerings to attempt to counter contractions in the job market.

(TGT) - Get Report

While peers such as

McDonalds

Wendy's Arby's Group

(WEN) - Get Report

, a $2 billion fast food chain that boasts more than 10,000 restaurant locations in 23 countries. Still, the company is managing to whet income investors' appetites with a 33.3% dividend increase that brings the company's dividend yield to a slightly more competitive 1.7%.Following the merger that blended two of the country's most recognizable quick-service restarant chains into Wendy's Arby's Group, the new company is still fighting to make an impression on fast-food customers.

That said, management is making good moves to differentiate the company's offerings from those of its larger competitors. With fewer than 10% of the chains' stores abroad, international opportunities could provide quick growth potential for Wendy's, especially in markets that have already been successfully tested by rivals.

Among WEN's biggest shareholders is the

iShares S&P 400 MidCap Value Index ETF

(IJJ) - Get Report

, an exchange-traded fund that owns shares of

Manpower

(MAN) - Get Report

and

BorgWarner

(BWA) - Get Report

in addition to its stake in the restaurant chain.
