It’s an impossible dream come true, like running a three-minute mile or hitting eight home runs in a single baseball game — recommending a group of stocks and seeing them rise an average 100%- plus during the next six months.

This dazzling achievement, part of the uranium boom, is the work of commodities expert Sean Brodrick, who last October recommended seven uranium investments — six stocks and one Canadian uranium fund. Since then, the seven have shot up between 30.6% and 156.8%, with the average increase an incredible 106.9%.

Chief reason for the runup: the surging price of uranium, up more than fivefold the last two years and 19% in the past week alone.

Citing a worsening supply squeeze and a phenomenal increase in demand, Mr. Brodrick, a uranium bull who plies his trade at the Safe Money Report investment newsletter in Jupiter, Fla., contends the rise in the price of the metal and uranium stocks is far from over, that “both have nowhere to go but a lot higher.”

Uranium, chiefly used for the creation of electric power, is thousands of time more efficient than fossil fuels. For example, the energy in one uranium fuel pellet — the size of the tip of a finger — is the equivalent of 17,000 cubic feet of natural gas, 1,780 pounds of coal, or 149 gallons of oil. About 19% of the country’s electricity comes from nuclear power.

Demand for uranium is far outstripping supply, with the world’s 435 mines providing enough to cover only 45% of the need. Mr. Brodrick figures the supply-demand squeeze should get much worse in the next few years, potentially sending prices sky-high. By 2015, he notes, some estimates put uranium oxide demand at 264 million pounds a year, nearly 55% higher than today’s 171 million pounds.

Two years ago, uranium traded at about $20 a pound. It’s now around $113, up from $72 in January. By yearend, Mr. Brodrick projects a surge to between $150 and $220. He concedes that’s a big jump, but said, “I’ve underestimated the pricing power of uranium before, and I don’t want to do it again.”

Also pushing up prices recently has been flooding at a couple of major uranium mines, one in Australia and another that’s supposed to come on stream soon in Canada.

Although he sees substantially higher uranium prices, Mr. Brodrick thinks the metal could weaken briefly in the short term. The chief reasons: The U.S. Department of Energy might sell some of its stockpiles into the market; likewise, a lot of speculators, sitting with some giant gains in the metal, may want to take some profits. Further, hedge funds have gotten into the uranium act, both in the metal and the stocks, and that’s likely to create a lot more volatility, Mr. Brodrick says.

What about the public’s concerns about the use of uranium to generate electric power? In the late 1970s, there were major operational problems at uranium plants in Chernobyl, Ukraine, and at Three Mile Island in Harrisburg, Pa., souring lots of people on uranium.

Mr. Brodrick says he thinks we’re in a new era, that concerns about global warming will cause populations here and abroad to eventually warm up to nuclear power plants because they emit zero greenhouse gases. Meanwhile, the rising number of proposed uranium plants suggests more are on the way. Globally, for example, 165 new plants are under proposal, 22 of which are designed for America, which has 103.

Mr. Brodrick sees a renaissance of American uranium mining, with entrepreneurs reopening a bunch of abandoned uranium mines in the west, notably in Texas, Wyoming, Arizona, and Utah.

While he believes uranium stocks still make investment sense despite their big gains, he cautions that they’re highly speculative. He also notes that “there are a lot of hucksters out there, so you really have to know what you’re doing and be careful to do your homework.” The key, he says, is to make sure the company you invest in has knowledgeable uranium people and sufficient funding.

His three favorite uranium stocks, each of which he says he believes will be at least 50% higher 12 months out, are Fronteer Development Group, Paladin, and Dennison Mines.

Another newsletter, the Complete Investor, serves up what it regards as another three attractive beneficiaries of the energy boom. One is Cameco, the world’s largest uranium miner, which, it’s noted, will see earnings soar as a result of the giant rise in uranium prices. The two others are diversified miners — Australia’s BHP Billiton and London-based Rio Tinto. Both, it’s noted, offer added safety because of their stakes in aluminum, copper, iron, coal, and other commodities.

The bottomline, if you believe our bulls: The uranium boom is just not about to run out of steam anytime soon; so hop aboard, but with care.
