5 Stocks Under $10 Worth Buying

If you've got $10, I have some stock ideas for you.

I've been singling out attractive opportunities in low-priced stocks since my original "5 Stocks Under $10" column 13 years ago, and I've seen plenty of stocks with pocket-change prices generate incredible gains.

There are risks, and they are readily apparent, given recent volatility. There are often good reasons for stocks to be ignored or beaten down. However, a market rally can work wonders for the unloved with positive catalysts in their pockets.

Let's go over my five picks from March 2009 -- when low-priced stocks bottomed out -- to prove my point.

*Bare Escentuals was acquired for $18.20 a share in 2010. Focus Media was acquired for $27.50 a share in 2013.

The average gain of 567% in a little more than five years is pretty remarkable. Yes, that also happened to be when the market was bottoming out, but that still blows away every major market index in that time.

Let's go over this month's picks.

Plug Power (PLUG -5.17%) -- $7.32
You won't find too many stocks hotter than Plug Power this year. The fuel cell specialist is up a whopping 372% this year, and things continue to look up as alternative energy grows in popularity. The biggest catalyst for Plug Power this year was when Wal-Mart, the world's largest retailer, announced that it was tripling the presence of its hydrogen fuel cell charging stations at its distribution centers.

Losses have been narrowing, and the market sees Plug Power turning profitable next year. Along the way, we're seeing growth on a tear. Analysts see revenue more than doubling this year, followed by a 79% top-line pop next year.

STMicroelectronics (STM -2.55%) -- $8.88
This may seem like a lousy time to warm up to STMicroelectronics. The Swiss semiconductor giant has surprised the market for three consecutive quarters by posting losses when analysts projected profits. With its next quarterly report set a week from today, the trend suggests that we're looking at another disappointing report.

However, at least the pros are ready for a quarterly deficit out of STMicroelectronics this time. They see a return to profitability during the current quarter, and that's important if it expects to sustain its healthy 4.5% dividend yield. The past year has been disheartening, but STMicroelectronics is fetching a reasonable 15 times next year's earnings forecast.

New Residential Investment (RITM 1.60%) -- $9.49
Mortgage real-estate investment trusts provide healthy yields, but there are naturally risks involved with real estate these days. New Residential stays a step ahead of the pack by specializing in mortgage servicing rights, a healthy stream of revenue that actually benefits from rising rates.

New Residential was spun off just 11 months ago, so it's not exactly a household name for yield chasers, but the logic of buying into REITs specializing in mortgage servicing rights is sound. As mortgage rates move higher, folks are less likely to refinance their loans, extending the value of these servicing rights. New Residential shelled out payouts of $0.495 per share through its abridged 2013. The healthy distributions should continue.

Inovio Pharmaceuticals (INO -5.10%) -- $2.53
Biotech stocks have corrected recently, giving investors with the risk tolerance to buy into feast or famine players working on potentially blockbuster treatments a compelling entry point. Inovio is a nascent biotech with a vaccine for HPV-caused pre-cancers and cancer working its way through the long FDA approval process. There's an important mid-stage data readout for the vaccine, VGX-3100, due likely this summer.

Inovio has no shortage of gamblers. Daily trading volume has averaged more than 8 million shares lately, and that's a lot for a stock commanding a $600 million market cap. The good news for those willing to wait is that Inovio was able to raise enough money last month to likely see it through at least 2017. That's a pretty big deal since biotech upstarts often have to deal with cash burn rates as much as the treatments that they're actually working on.

Harmonic (HLIT -3.10%) -- $6.72
You can find companies that are starting to put it all together in the bargain-priced bin. Harmonic seems to be doing more than a few things right. It has posted better-than-expected earnings in its three past quarters, and the growth trajectory on the bottom line is encouraging. Wall Street sees a profit of $0.29 a share this year after posting net income of $0.17 per share last year. They see earnings of $0.37 per share come next year.

Harmonic helps video content creators and distributors in creating, preparing, and delivering programming for television and new media platforms. It reports tomorrow afternoon, giving Harmonic a good shot at stretching its streak of market-thumping results to four quarters in a row.

Five for the road
These five stocks aren't trading in the single digits by accident. If I'm right about the catalysts, though, they may not be trading in the single digits for too much longer.
