????提起泰瑞和詹尼這對格里高利夫婦的投資組合，可能會讓人覺得有點(diǎn)懸。退休的格里高利夫婦如今住在檀香山，他們差不多將畢生的積蓄約250萬美元都買了一只股票：蘋果公司（Apple Inc.）。

????格里高利夫婦如此執(zhí)著一念地投資蘋果股票，似乎與媒體（如《財富》雜志）和主流投資策略師們給出的建議格格不入。投資者不能將所有的資金放在一只股票里，退休人員尤其如此，他們的投資組合更應(yīng)注重收益和財富保值，不應(yīng)追求成長和冒險。沒說錯吧?

????哦，在您準(zhǔn)備對格里高利夫婦的投資做法嗤之以鼻前，不妨問問自己下面這些問題。您住在一套離檀香山威基基海灘幾步之遙、價值65萬美元的豪華公寓里嗎？您有這樣的智慧、信念和堅(jiān)持，將2004年一筆20萬美元的投資（投資一家當(dāng)時似乎已過氣、市場份額僅3%的電腦公司的股票）變成了近300萬美元的財富，幫助實(shí)現(xiàn)了提前退休的夢想嗎？“所有的建議都是分散投資，但以我們的經(jīng)驗(yàn)，分散投資并不管用，”62歲的詹尼?格里高利表示。她和她58歲的丈夫泰瑞在退休前都是從事廣告行業(yè)。泰瑞說：“分散投資可能有助于財富保值，但我們需要讓財富增長?！?/p>

????格里高利夫婦的情況并非個案。在MacObserver.com留言板、Proboards的蘋果金融留言板以及Braeburn Group網(wǎng)站的投資者論壇中等等，到處都是蘋果的鐵桿粉絲驕傲地宣稱，自己將所有或者大部分的錢買了蘋果股票。

????對于他們中的很多人而言，投資蘋果股票——持續(xù)關(guān)注蘋果公司（往往每天都要花上幾個小時）——已不只是一項(xiàng)金融投資那么簡單。它是一個更高的追求?！疤O果不光是一家電子設(shè)備或裝置的生產(chǎn)商，”只投資蘋果股票的羅伯特?保羅?雷濤是加州伯班克一家天主教堂的營運(yùn)總監(jiān)，也是Braeburn Group蘋果獨(dú)立分析師的創(chuàng)立人（雷濤對這家網(wǎng)站的命名也是帶有蘋果特色，具有“智慧和復(fù)合特色”）。“我相信，蘋果產(chǎn)品的設(shè)計(jì)和功能給人們帶來了美好的體驗(yàn)?！?/p>

????晨星（Morningstar）數(shù)據(jù)顯示，十年前沒有一家共同基金將蘋果列為第一大持股。如今，這個數(shù)字已增至683家，差不多每8家基金中就有1家是這樣。有些基金在美國國稅局（IRS）關(guān)于共同基金分散投資條例許可的范圍內(nèi)，幾乎將所有額度都投入了蘋果股票。有12只基金持有的蘋果股票已達(dá)到或超過了資產(chǎn)總額的20%。如今還有一只單單投資蘋果的對沖基金B(yǎng)ullish Cross Asset Management，只交易蘋果股票及其期權(quán)。管理這只基金的安迪?扎基是一位獨(dú)立的蘋果分析師，也是《財富》雜志網(wǎng)站的供稿人。

????Just thinking about Terry and Jeanne Gregory's portfolio can be a little scary. Retirees now living in Honolulu, the Gregorys have basically their entire life savings -- about $2.5 million -- invested in just one stock: Apple Inc.

????The Gregorys' love affair with Apple (AAPL) flouts every bit of investment advice doled out by magazines like this one and by mainstream investment strategists. No investor -- especially a retiree whose portfolio should be geared toward income and wealth preservation, not growth and risk taking -- should have all his money invested in just one stock. Right?

????Well, before you dismiss the Gregorys as fools, ask yourself these questions. Do you live in a $650,000 luxury condo a stone's throw from Waikiki Beach? And did you have the smarts, conviction, and stick-to-itiveness to turn a $200,000 investment in 2004 -- in a seemingly past-its-prime computer stock with a mere 3% market share -- into a nearly $3 million windfall that financed a dream early retirement? "All the advice was to diversify, but in our experience, diversification didn't really work," says Jeanne Gregory, 62, who, like her husband, Terry, 58, is retired from the advertising industry. "Diversification," adds Terry, "may be good for preserving your wealth, but we needed our wealth to grow."

????The Gregorys are not alone. Online message boards like the MacObserver.com boards, Proboards' Apple Finance Board, and the investor forums on the Braeburn Group website are filled with Apple obsessives who proudly admit to having all or most of their money in Apple.

????For many of these folks, investing in the stock -- and keeping tabs on the company (often for hours a day) -- isn't just a financial pursuit. It's a higher calling. "Apple is not just a maker of widgets or digital devices," says all-Apple investor Robert Paul Leitao, director of operations for a Catholic church in Burbank, Calif., and also the founder of the Braeburn Group of independent Apple analysts (a website Leitao named after an apple variety with "smart and complex flavor"). "I believe the design and functionality of Apple products speak to the dignity of the human experience."

????Ten years ago there wasn't a single mutual fund that counted Apple as its largest holding, according to Morningstar. Today there are 683 -- or one out of every eight funds. Some of the funds are just about as all-in on Apple as the IRS rules for mutual fund diversification allow. There are 12 funds with 20% or more of their assets in Apple. There's now an Apple-only hedge fund -- Bullish Cross Asset Management, which trades both AAPL shares and options -- run by Andy Zaky, an independent Apple analyst and a Fortune.com contributor.
