????能源價(jià)格受到巨大沖擊的原因往往是經(jīng)濟(jì)嚴(yán)重失衡——比如中東局勢(shì)緊張帶來(lái)對(duì)石油供給的恐慌,；或者經(jīng)濟(jì)衰退造成需求萎縮,，使得能源價(jià)格直線下降,。

????但這次油價(jià)暴跌（從夏天的每桶105美元降至最近的約60美元，創(chuàng)2009年以來(lái)最低）并非全球危機(jī)所致,。而是由于對(duì)歐洲,、日本和中國(guó)經(jīng)濟(jì)增長(zhǎng)的擔(dān)憂，以及沙特,、俄羅斯,、利比亞和美國(guó)石油產(chǎn)量的增加。

????別指望生產(chǎn)商會(huì)減產(chǎn),，特別是在美國(guó)——在那里,，蓬勃發(fā)展的頁(yè)巖油行業(yè)在油價(jià)下跌后仍可盈利。高盛（Goldman Sachs）分析師預(yù)計(jì),，2015年石油產(chǎn)量和消費(fèi)量都將上升,，但供給的增長(zhǎng)將超過(guò)需求。這應(yīng)該會(huì)進(jìn)一步壓低油價(jià),。以下將為大家介紹如何才能保護(hù)自己的投資組合并從石油供給過(guò)剩中獲利,。

????你的行動(dòng)計(jì)劃

????降低新興市場(chǎng)配置。投資公司Osterweis首席執(zhí)行官馬修?柏勒指出,，俄羅斯和伊朗需要油價(jià)保持在每桶100美元以上，來(lái)避免出現(xiàn)大量預(yù)算赤字,。沙特則一直強(qiáng)硬地拒絕減產(chǎn),。基金公司Forester Capital Management負(fù)責(zé)人湯姆?弗雷斯特說(shuō),，如果沙特繼續(xù)這樣做,，“其他新興市場(chǎng)就可能受到不利影響”。這是一個(gè)把新興市場(chǎng)投資份額降到5%的充分理由,。

????押注運(yùn)輸股,。經(jīng)濟(jì)學(xué)家愛(ài)德華?亞德尼認(rèn)為，由于每加侖汽油價(jià)格預(yù)計(jì)將比2014年的高點(diǎn)低30美分,，“交通運(yùn)輸行業(yè)將出現(xiàn)巨額利潤(rùn),。”這幾年鐵路股一直高歌猛進(jìn),。因此,，投資可以向較便宜的卡車運(yùn)輸企業(yè)或者航空公司傾斜，后者將從油價(jià)下跌和消費(fèi)支出增長(zhǎng)中受益,。SPDR標(biāo)普交通運(yùn)輸交易所交易基金（SPDR S&P Transportation ETF）的三分之二都投入了這些行業(yè),。

????保留低油耗汽車概念股。定價(jià)網(wǎng)站TrueCar總裁約翰?克拉夫茨克說(shuō)：“汽油價(jià)格下跌時(shí),，立即就會(huì)看到人們?cè)谶x擇汽車方面所受的影響,?！逼噺S商已經(jīng)開(kāi)始打折銷售超級(jí)省油的汽車，比如,，福特（Ford）?？怂闺妱?dòng)車的售價(jià)最近下跌了6000美元?？死虼目诉€預(yù)計(jì),，使用汽油發(fā)動(dòng)機(jī)的中型和緊湊型轎車很快就會(huì)報(bào)出“極為美妙的價(jià)格”，它們每加侖汽油能跑30多英里（約50公里）,。其他人可能會(huì)選擇更大的——SUV重新受到關(guān)注,。但逆市操作也許能帶來(lái)長(zhǎng)線收益。（財(cái)富中文網(wǎng)）

????Big jolts to energy prices are often caused by major economic imbalances—like rising tensions in the Middle East setting off supply scares. Or a dropoff in demand from a recession, causing prices to plummet.

????This time there is no global crisis behind crude’s slide (from $105 a barrel in the summer to around $60 recently, its lowest level since 2009). Instead to blame: fresh worries about growth in Europe, Japan, and China, set against rising production in Saudi Arabia, Russia, Libya, and the U.S.

????Don’t expect producers to turn off the spigot just yet, especially in the U.S., where the burgeoning fracking industry can still profit at lower prices. Analysts at Goldman Sachs predict output and use will both grow in 2015, but supply will outpace demand. That should push oil down further. Here’s how you can protect your portfolio and profit from the oil glut.

????Your Action Plan

????Ease off emerging markets.Russia and Iran need oil at or above $100 a barrel to avoid major budget deficits, says Matthew Berler, CEO of investment firm Osterweis. The Saudis have been playing hardball by refusing to cut production, and if they continue, “other parts of the emerging markets could get hit,” says Tom Forester, head of Forester Capital Management. Good reason to cut emerging markets to 5% of your portfolio.

????Bet on shipping.With gas expected to stay 30￠ a gallon below 2014 highs, “the transportation industry is getting a big windfall,” says economist Edward Yardeni. Railroad stocks have been on a tear for years. So lean toward cheaper truckers and airlines, which benefit from sinking prices and rising spending. Two-thirds of SPDR S&P Transportation ETF is in those industries.

????Save on a gas sipper.“When gas prices go down, you see an immediate impact on vehicle choice,” says John Krafcik, president of pricing site TrueCar. Automakers have already begun discounting super-fuel-?efficient cars—the Ford Focus Electric recently fell $6,000—and Krafcik expects to soon see “fantastic deals” on gas-engine midsize and compact sedans, which can get 30-plus mpg. Everyone else may be buying big—the SUV is back!—but a contrarian play may pay off in the long haul.
