Long-term growth stock expert Alexander Green sees long-term upside potential for conservative investors willing to invest along side of Warren Buffett.

Here, the investment director of The Oxford Club reviews Berkshire Hathaway (NYSE: BRK.B), a holding in his model portfolio.

"The market surprised investors with the magnitude of its drop over the last year and a half. Then it surprised them again with a furious rally that began in early March.

"What lies just ahead? No one knows for sure, of course. But we do know several investments that are attractively priced at current levels, such as Berkshire Hathaway (BRK.B), a conservative choice, run by investment great Warren Buffett.

This is a follow-up on the short term results comparing the Williams Companies Inc. (NYSE: WMB) to Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), and Berkshire Hathaway Inc. (NYSE: BRK.B).

I wrote a series of stories about why I thought WMB would outperform the other more popular stocks and two weeks is not much of a test unless you have been trading on my suggestions instead of investing.

The final post was Serious Money: Better than Apple, Google, Microsoft & Berkshire Hathaway, Part 5 if anyone cares to go back and review that.

This is the final post on why I believe you would be better off investing in the Williams Companies Inc. (NYSE: WMB) than you would in Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), or Berkshire Hathaway Inc. (NYSE: BRK.B).

I hope I made the case this week outlining the deeper value proposition, competitive advantages, reduced risk, and of course the dividend that make Williams the preferable investment for the long term.

This week I have been evaluating the Williams Companies Inc. (NYSE: WMB), a stock that I think would make a good core holding for anyone seeking a dependable dividend, growth potential, and relatively low risk given its current price.

The price was $13.77 when I started the series and $13.00 when I myself bought in.

After the first three posts, I hope the case has been made, but we will continue nevertheless looking at Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), and Berkshire Hathaway Inc. (NYSE: BRK.B) for more supporting evidence.

Over the past three years, I have found occasion to recommend these stocks and to pan them when their prices became ridiculous, not always with perfect timing. This week I have been expressing my preference for one over the rest, the Williams Companies Inc. (NYSE: WMB).

Part 3 continues to compare Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), and Berkshire Hathaway Inc. (NYSE: BRK.B) to Williams using a variety of common criteria.

In my first post on the subject yesterday, I discussed some of the advantages that Williams Companies Inc. (NYSE: WMB) might have over more popular stock "brands" like Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG), Microsoft Corp. (NASDAQ: MSFT) and Berkshire Hathaway Inc. (NYSE: BRK.B) -- all great companies.

I highlighted the yield, book value, and spread between natural gas and oil, concluding that even "my pal Warren" would prefer Williams. Today I continue to look at the various valuation metrics one might contemplate in examining a stock's potential.

Last year most analysts proclaimed that the market would be up by the years end. The only accurate part of the analysis was that the year did end; although not well.

When Burlington Northern Santa Fe (NYSE: BNI) was trading at $114 analysts were silent. When it dropped below $100 and then $90 a share I do not recall anyone writing anything accept that "my pal Warren" was buying. At $80, and then $70 not more than a whisper.

Then yesterday when BNI was trading in the mid $60's (it closed at $64.97) Citigroup (NYSE: C) Investment Research analyst Matthew Troy cut shares of Burlington Northern Santa Fe Corp. and Canadian Pacific Railway Ltd. to "Sell" from "Hold."

If I write about Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG), Microsoft Corp. (NASDAQ: MSFT) or even one of my favorites Berkshire Hathaway Inc. (NYSE: BRK.B). I know that readership will be higher than if I write about less popular names.

Most recently this happened when I wrote about Williams Companies Inc. (NYSE: WMB) and to my disappointment interest was not high. Maybe it was the header: Chasing Value: Williams has the pipes and it's not blowing smoke -- go back and read it.

"Though the past year has been tough for Warren Buffett, we still like Berkshire Hathaway (NYSE: BRK.B), which we believe is well-positioned for the year ahead," says Paul Tracy.

In his StreetAuthority Market Advisor, he looks at the holding company which is a position in his "undervalued gems" model portfolio. Here's his review.

"For only the second time in the investment-based company's 44 years, Buffett saw the book value of Berkshire drop. Of course his book value decline of 9.6% should be put in context with the 37% loss incurred by the S&P 500.

One of our reader's who blesses us with frequent comment's, B. Harrison, left the following tidbit for us recently (responding to: Buffett suffers big losses at Berkshire Hathaway) and I thought I would share it because this sentiment comes to us frequently.

• "And the American people are simply apathetically sitting back while our CORRUPT Congress who enabled and allowed all of the corporate FRAUDS, continues to allow the CORRUPT CEOs and Boards of Directors run those corporations, and to keep their ill gotten "weath" that they amassed while mismanaging the corporations, and orchestrating and perpetuating all of those FRAUDS."

I do not agree that the American people are "apathetically sitting back".... They are voicing their opinions on the web, in letters and emails to their representatives, they take to the streets and protest, they sell the stock of poorly run companies and file class action suits. The truth is that they are frustrated because our representatives have an unwavering singular focus, and that is to sustain themselves in office. Nothing takes a higher priority then that; it's called political self preservation.

Bad times can bring out the best and the worst of us. There is a character with a huge heart and apparently stacks of cash for needy folks willing to wait in line for it in Time Square.

He has been cast as "Bailout Bill" and he has created a stir because he is giving away money directly to those in need, figuring that the folks on the bottom rung of the ladder need just as much help as those at the top, that the government has been bailing out.

According to reports, In order to get the money people have to go to the 'Bailout Booth' in the heart of Manhattan's Times Square; to a small cubicle, where, depending on your story you can get a cash stipend to help out with a present financial dilemma.

When you're at the top of your game you get a lot of attention and Warren Buffett was the focus of a Barron's story this week titled Warren's Unhappy New Year (subscription required).

The article points out that 'my pal Warren' has been overly optimistic about his financial holdings: American Express (NYSE: AXP), U.S. Bancorp (NYSE: USB) and Wells Fargo (NYSE: WFC).

All three companies have been hit hard the last few weeks, bringing down Berkshire Hathaway (NYSE: BRK.A). Last week, USB and WFC were trading about 50% off the year-end prices.

Does it make sense for Barron's to do a write-up about a turn of events over a three week period given a 50-year track record? Surely you jest Andrew Barry.

I made it through mid-year of tracking my 2008 picks from last December and then -- Wham! -- I went from a slight advantage to being humbled badly by the market. However difficult it is to display your failings, once again I will share all of the horrors since I posted the original story Chasing Value: Final list -- 8 stocks for 2008.

The master is still the master, Warren Buffett and his life's work Berkshire Hathaway (NYSE: BRK.B) beat me easily as well as the three indices I tracked.

For the most part, unless you started shorting stocks, there was no place to hide and most of my picks were big losers. There were two that beat Buffett and the market. The defense sector was the defensive sector it was supposed to be with Raytheon Company (NYSE: RTN) doing well on a relative scale. The other place you could have a morsel of stability was utilities and Huaneng Power International (ADR) (NYSE: HNP) lost less but not by much.

This post is part of our feature on Money Winners of 2008. See all 20.

Well, "my pal Warren" did it again. "The richest man in the world" -- it has a nice ring to it.

Though the moniker did not last throughout the year due to the violent markets, and his significant holdings in insurance, Geico and General RE; banking, US Bancorp (NYSE: USB) and Wells Fargo (NYSE: WFC); and credit card company American Express (NYSE: AXP), which all dropped, he is still viewed as the top investment guru in the world, deserving his title -- the Oracle of Omaha. These are likely only temporary setbacks and he may very well be back on top soon.

Warren Buffett has been alternating places with Microsoft (NASDAQ: MSFT) founder Bill Gates over the past decade. Since Microsoft shares are only down about 35% this year, less than the overall market, and since that remains his largest holding, Gates edged out Buffett at last measure. Although Buffett is notorious for not investing in "tech-stocks," he has stated he did buy 100 shares of Microsoft after he and Gates became friends.

It has been quite a year indeed for Buffett because in all the market turmoil he has remained very active, and he has advised both presidential candidates when asked, though he has supported the Democratic Party and president-elect Barack Obama, who has more actively sought his advice as of late.

Here's a shocker (although not really to those paying attention), if you would have invested in Berkshire Hathaway Inc. (NYSE: BRK.B) three years ago instead of the wonder company Google, Inc. (NASDAQ: GOOG) you would be 30% ahead right now.

'My pal Warren' never ceases to amaze and for all the excitement that Google has brought to the investment world, the stock market in particular, and the internet -- scaring the likes of Yahoo! Inc. (NASDAQ: YHOO) and Microsoft Corporation (NASDAQ: MSFT), it has not done all that much.

For those that took a ride on the Google band wagon at the beginning you are now poorer than you would have been taking a more traditional investing approach and you did it all the while taking more risk. More risk and less reward is a bad thing.
