I love to kick off the new trading week by taking a quick peek at companies that have just hiked their dividends. It's not just about the money. A company that's loosening its purse strings probably has improving fundamentals to back up that generosity.

Readers of the Income Investor newsletter can certainly appreciate that kind of thinking. Let's take a closer look at four of the companies that inched their payouts higher over the past week.

Let's start with Men's Wearhouse (NYSE: MW). The suit seller gave its quarterly dividend rate a welcome alteration, taking the sleeves out by another 17% to $0.07 a share.

It may not seem like much, but rival Jos. A Bank (Nasdaq: JOSB) doesn't even pay a dividend. The hike at Men's Wearhouse comes even after the apparel retailer dramatically shaved its holiday-quarter profit outlook last month.

Elsewhere, UPS (NYSE: UPS) is delivering a fatter yield. The world leader in package delivery is boosting its quarterly distributions by 7% to $0.45 a share. This Income Investor newsletter recommendation has doubled its dividend over the past five years.

What's in your wallet? A lot more than you think, if you're a Capital One (NYSE: COF) shareholder. The credit card issuer is coming through with a huge uptick in its payout rate. Investors who were getting just $0.027 a share will now enjoy $0.375 a share.

With its new yield of 2.7%, Capital One is still a dwarf among the financial heavies. Companies like Citigroup (NYSE: C) and Bank of America (NYSE: BAC) have substantially higher yields. However, it's comforting to see Capital One -- a company that would seem to have plenty to risk, if borrowers continue to default on their short-term debt -- feel upbeat enough about its future to pull off this aggressive update.

Finally, McGraw-Hill (NYSE: MHP) is turning the page. The book and financial-analysis publisher is hiking its quarterly disbursements by 7% to $0.22 a share. McGraw-Hill has now raised its dividend in each of the past 35 years.
