Dividends are on the rise right now. And while consistent payers like Sysco always have some allure, investors should watch for big jumps like the ones at Corning and Union Pacific.

Dividends are back in style.

Of course, for some companies, they never stopped being a key way to return profits to shareholders. For example, when food distributor Sysco (SYY) raised its dividend this quarter by 3.8%, it marked the company’s 10th consecutive annual dividend increase.

The 9% annual dividend increase declared on November 21 by Lancaster Colony (LANC), a manufacturer of candles and specialty foods, beat even that record of consistency. Lancaster Colony is one of only 16 US companies to have increased cash dividends every year for 49 years or more.

But I’m talking about something very different than those examples of dividend consistency. This quarter, I’m seeing companies that have been relative dividend tightwads decide not only to raise their payments, but raise them big time.

I’m seeing 12%, 15%, and even 50% and 67% dividend increases. I’ve even seen one company raise its regular annual dividend payout twice this year.

For these companies, this isn’t business as usual—and it signals something new in the way these companies have decided to support their share prices in a very rough stock market.

The good news for investors, of course, is that these dividend increases are coming at a time when lasting price appreciation has become extremely hard to come by.

What Works and What Doesn’t
What’s going on? I think we’re seeing a recognition by some companies that share buybacks as a way to boost share prices and impress shareholders aren’t very effective right now.

Part of that might come down to buyback fatigue. The volume of buybacks, in which companies purchase their own shares in the markets, peaked with $914 billion authorized in 2007. This year, the total so far comes to $445 billion—the highest since 2007.

But when every company is doing buybacks, they don’t make a company stand out. Once buybacks become a regular piece of corporate financial management, they simply don’t convey much information to investors about what a company’s management thinks about future performance.

And, I’d argue, investors have become justifiably cynical about buybacks. Remember that total for 2007? That was for announced buybacks. Once a company has announced a buyback program with suitable fanfare, it isn’t under any legal obligation to actually buy the full dollar amount of shares authorized.

If the future turns out to be not quite so rosy—or so profitable—then never mind.

Of course, there’s also the problem that buybacks may simply not do a good job of delivering value to shareholders. Research by Fortuna Advisors shows that the median S&P 500 company engaged in stock buybacks from 2004 to 2008 delivered a return on investment of 3%. Seventy-five percent of such companies delivered a return on investment of less than 10%.

The data suggest, certainly, that these companies would have been better off investing in their own businesses—if they could identify opportunities that would return more than 10%. And if they couldn’t find those opportunities, they should simply have returned the cash to shareholders in the form of dividends.

And don’t forget the allure of a dividend in a stock market that isn’t delivering much in the way of capital gains. If you’re still bullish, a dividend is a way to get paid while you wait for the turn in prices.

If you’re less optimistic, a dividend yield of 3% or 4% or more is still attractive when the alternative is a ten-year Treasury paying less than 2%.

4 Big Increases
Some of the dividend increases I’ve seen recently look like naked attempts—and good for management for recognizing the opportunity to make an impression on yield-starved investors—to push a stock’s yield above that offered by a ten-year Treasury.

For example, Johnson Controls (JCI) raised its dividend 12.5% on November 16 to a projected annual yield of 2.5%. When Emerson Electric (EMR) raised its annual dividend by almost 16%, the company wound up with a 3.4% projected yield on its shares.

(What’s a projected yield? It’s the yield that you get looking forward at the declared dividend rate over the next four quarters divided by the current share price. In the case of a company that has just raised its dividend, I think this gives investors a better picture of a stock’s yield than looking at the old, trailing 12-month dividend payout.)

Other companies are still playing the old dividend-as-signal game, where a substantial dividend increase isn’t enough to turn a piddling yield into a competitive payout but is an effective shout-out announcing that a company is back after a recent slide.

I’d put the 40% dividend increase at Whole Foods Market (WFM) in that category. The 40% jump did grab my attention, even if the 0.6% projected yield wasn’t exactly mouthwatering.

The same goes for the big 67% dividend increase announced on November 3 by Starwood Hotels & Resorts (HOT). That brings the annual payout to 50 cents a share, from 30 cents.

The projected yield is just 0.6%, but the boost is big enough to convince me that management really, really believes that the company’s mix of 70% international and 30% US properties, and its strategy of managing rather than owning, will continue to work even if the global economy is relatively soft in 2012.

And the dividend announcement is a good counter to the disappointing guidance for fiscal 2012 that Starwood delivered on Oct. 27, when it reported fourth-quarter earnings for fiscal 2011. For fiscal 2012, the company said, earnings per share would be $1.96 to $2.25 versus the Wall Street consensus forecast of $2.25.

The hike in the dividend, then, serves as a reminder that the lowered guidance doesn’t suggest anything like the end of the world for the company’s business.

2 More Telling Dividend Jumps
I think a dividend increase like the 50% jump announced by Corning (GLW) on October 6 serves both purposes. First, it pushed Corning’s projected dividend yield up to 2.1%, above the yield on the ten-year Treasury.

Second, it signaled that the company, which would announce some pretty negative trends for demand for its liquid crystal display (LCD) glass in the fourth quarter, was confident that demand would recover in 2012.

All things considered, though, what I really like to see in a dividend increase right now is a jump that puts the yield over the ten-year Treasury rate, and that signals not only that the future isn’t grim but that it might be downright rosy.

That’s the combined message that I think Union Pacific (UNP) sent when it raised its dividend not once, but twice this year. The two increases brought the projected yield on the railroad’s shares to 2.4%.

When the company reported third-quarter earnings on October 20, it said revenue had climbed 15.7% from the third quarter of 2010, as total carloads carried grew by 1%. Four of the railroad’s six business groups—those for autos, industrial products, energy, and chemicals—reported increased volumes.

And for 2012? Standard & Poor’s projects a 3% increase in volume and a 6.5% increase in revenue (after the 15% revenue growth in 2011). Credit Suisse is less optimistic about growth in volumes, projecting a 2% increase, but more optimistic on pricing, which translates into an estimated 18% increase in earnings in 2012.

S&P puts a 12-month target on the stock of $107 a share. (It closed at $98.25 on November 22.) Credit Suisse has set its target at $120 a share.

If I can extrapolate from Union Pacific’s two dividend increases in 2011, I’d say the railroad would agree with the higher target.

That’s obviously just the company’s opinion, and predicting growth in 2012 in the US economy is a tough job. But as we try to cut through the confusion, I’d suggest that investors pay special attention to companies that are letting their dividend increases do the talking.
