Just as we examine companies each week that may be rising past their fair value, we can also find companies potentially trading at bargain prices. While many investors would rather have nothing to do with companies tipping the scales at 52-week lows, I think it makes a lot of sense to determine whether the market has overreacted to the downside, just as we often do to the upside.

Here's a look at three fallen angels trading near their 52-week lows that could be worth buying.

Dial up this dividend
Dial-up Internet connections might be for the dinosaurs, and the days of high growth are long gone for United Online (Nasdaq: UNTD), but that doesn't mean you should ignore the stock at these dirt cheap levels.

While revenue is more or less flat these days, United Online's strict cost controls keep profits moving slightly higher, which, in turn, keeps its dividend at very healthy levels. Currently yielding more than 8%, United Online could offer an investment payback in as little as nine years if it can keep that yield up! Former Internet service providing peer Earthlink (Nasdaq: ELNK) has taken to transforming itself into an IT company in order to save its petering revenue stream, leaving the low-cost ISP space almost exclusively to United Online. Clearly not the most exciting tech company by any means, United Online is trading at just 90% of book value and seven times forward earnings. I don't see the company getting much cheaper from here.

Foreign exchange
Who said students were the only thing you could exchange across continents? Telkom Indonesia (NYSE: TLK) is yet another foreign telecom that has wound up in the delectable dividend column.

The company is currently offering a dividend yield of 7.5% and has grown that yield by an annual rate north of 20% over the past decade. Foreign telecoms aren't going to knock your socks off with enormous growth rates, but their predictable levels of cash flow and lack of competition often make for a consistent dividend and slow but steady growth. Telkom Indonesia has grown revenue fourfold since 2001 and is valued at a reasonable 11 times next year's earnings. Relative to some domestic alternatives, this company offers a good balance of value and income, and it just might be a nice match for a conservatively run portfolio.

An ETF I can dig
Over the past couple of weeks it's become apparent to me just how inexpensive much of the gold sector has become. While I've had fun picking apart various gold miners that could be attractive plays, this week I'm going to suggest lumping them all together in the Global X Pure Gold Miners ETF (AMEX: GGGG).

Not only does gold provide a great hedge against inflation -- and, in recent years, against market downturns -- but the fund itself offers a reasonably low 0.59% annual management fee. Its largest holding is Eldorado Gold (NYSE: EGO), a company with rising short interest that I recently profiled as a solid income producer with expenses that are well under control and increasing output. I don't think you could go wrong with this basket in your portfolio.

Foolish roundup
This week's focus was on high-yielding dividends that could be had on the cheap and ways you can protect yourself from a toppy market and inflation. I'm so confident these three names will bounce off their lows that I'm going to make a CAPScall of outperform on each one.
