Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Berkshire Hathaway Inc. (BRK.A) announced improved results year over year, with book value up nearly 20%.
• BJ's Wholesale Club Inc. (BJ) Q4 earnings were in line with expectations but guidance for the year fell short.
• Cbeyond Inc. (CBEY) received an analyst's downgrade and lowered price target following its Q4 results.
• Costco Wholesale Corp. (COST) strong Q2 results fell short of analysts' estimates and shares declined.
• Dress Barn Inc. (DBRN) said it swung to a profit in Q2 and same-store sales increased, and it raised its outlook.

Yes it can. Berkshire Hathaway Inc. (BRK.B) can outperform Apple Inc. (AAPL) in 2010. That was my thesis in December (see Buffett's Berkshire vs Jobs' Apple for 2010?) and I still believe all the Apple hype in the world will still succumb to a solid value proposition in the long run.

While Apple was reaching new all time highs Berkshire was treading water through 2009. However, after a monster run-up Apple is taking a breather.

Analyst Upgrades

• Piper Jaffray upgraded Tractor Supply Co. (TSCO) to neutral to underweight ahead of the company's investment meeting Tuesday and raised its target on shares to $55 from $46.
• Barclays upgraded Norfolk Southern (NSC) to overweight from equal weight, citing earning potential and core price fundamentals. The firm raised its target to $52 from $55.
• KeyBanc upgraded Denbury Resources (DNR) to buy from hold based on expectations that the EAC acquisition has material value that is not reflected in shares. The firm has a $19 target on shares.
• BP Plc (BP) was upgraded to buy from neutral at BofA/Merrill.
• Abercrombie & Fitch (ANF) was upgraded to neutral from underperform at Cowen.
• Rowan Companies (RDC) was upgraded to sector perform from underperform at RBC Capital.

Sardar Biglari has done an admirable job of turning around operations at Steak 'n Shake (SNS), but over the past few months, he's made a few less-than-subtle efforts to imitate his idol Warren Buffett.

Back in December, he announced that he would do a 1-for-20 reverse split of the stock to boost the share price over $300 and "dissuade speculators." "We are attempting to eliminate those who erroneously think that it is easier for a $10 stock to go to $20 than a $200 one to go to $400," he wrote in a letter to shareholders.

In its annual letter to shareholders, Berkshire Hathaway Inc. (BRK.A) reported net income of $8.1 billion and revenue of $112 billion for 2009. That's an improvement over the net income of $5.0 billion and revenue of $108 billion in 2008. However, net income in 2007 totaled $13.2 billion.

In dollar terms, the conglomerate's book value rose 19.8% last year to $21.8 billion, or $84,487 per share. That was the best gain since 2003, but trailed the S&P 500's return of 26.5% for the year.

As always, there is a volume of speculation after the much anticipated release of the quarterly changes in holdings report from Berkshire Hathaway (BRK.A). While leaving all the deep analytical number crunching for greater minds than my own, I'd like to take a look at what Warren Buffett could be telling us through his company's latest form 13F.

Why has Warren Buffett swallowed Burlington Northern Santa Fe (BNI) while letting go of Norfolk Southern (NSC) and Union Pacific (UNP)? Being the master of due diligence, Mr. Buffett has most likely determined that BNI is the most attractive of the three. The future of rail transport is all but guaranteed to shine, and I believe that Mr. Buffett has exited the other two rail companies simply to avoid conflict of interest issues.

U.S. stock futures fell Friday morning as investors were caught off guard when China hiked its banks' reserve requirement again. It didn't help that the eurozone economies' growth seems to have wilted in the last quarter. Wall Street also awaits several key economic data, including retail sales.

The People's Bank of China announced Friday it is raising the banks' reserve requirement ratio -- reserves banks must set aside -- by 0.5 percentage points, marking the second such action this year. China is attempting to cool a credit boom without resorting to interest rate hikes that might derail a recovery in the world's third-largest economy. While the move was in line with expectations, it still sent dampened global sentiment as investors worried about the impact of monetary tightening on global economic growth.

Wal-Mart (WMT) closed at $53.43. WMT's volatility is flat on tight trading range as it is expected to report Q4 EPS on February 18. February put option implied volatility is at 20, March and June puts are at 21; near its 26-week average of 21, according to Track Data, suggesting non-directional price movement.

Three stocks with IV rise on January 29; Berkshire Hathaway (BRK/B) +9%, Focus Media (FMCN) + 8%, Talbots (TLB) +6% according to IVolatility.

Berkshire Hathaway Class B (BRK.B - option chain) shares are are on the move today after Standard & Poor's announced that the stock will be added to its benchmark S&P 500 index, replacing Burlington Northern Santa Fe (BNI), which will be acquired by Berkshire. BRK.B will also be added to the S&P 100. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on BRK.B, which is now possible with the recent 50:1 stock split.

BRK.B opened this morning at $73.28. So far today the stock has hit a low of $70.82 and a high of $73.28. As of 12:00, BRK.B is trading at $71.08 up $3.09 (4.5%). The chart for BRK.B looks bullish.

The financial world was rocked, more or less, when Berkshire Hathaway (BRK.B) recently announced a plan to split its B shares -- billionaire investor Warren Buffett, the company's chairman and CEO, famously refused to split the stock for years. (In fact, the A shares are still trading in six-digit territory, upwards of $100,000 apiece.)

On Monday, option players didn't hesitate to express their reservations about the stock split. During the course of the session, speculators on the International Securities Exchange (ISE) bought to open 4,736 puts on BRK.B, compared to just 2,559 calls. The single-day put/call volume ratio arrived at 1.85, with bearish bets nearly doubling their bullish counterparts.

A new year is upon us and like the beginnings of any year, and even more so, a decade, the predictions are flying fast and furious.

The start of 2010 is bringing out every analyst, talking head, business journalist, periodical and newsletter propagator, sportscaster, palm reader, taro card interpreter, astrologist, medium and madam making predictions to garner attention, entertain and even profit. Apologies to anyone I left out.

During my tenure at BloggingStocks I have expressed my opinion often about the contribution that dividends make to your overall return. Most shrewd investors, and especially "my pal Warren," know this and understand why I re-emphasize the point when I make my annual selections.

By now I hope you have had a chance to peruse my picks for 2010. If not the links below will give you another opportunity.

The first four picks were all from the contenders list, but here I reach back to earlier in the year, when in May, I wrote about why I thought Williams Companies Inc. (WMB) would outperform four other, more popular stocks.

I compared it to Apple Inc. (AAPL), Google Inc. (GOOG), Microsoft Corp. (MSFT) and Berkshire Hathaway Inc. (BRK.B).

During the past seven months this turned out to be true for half the period, but Apple came on strong and passed it by the second review.

This year's selections do not seem to offer the same dividend opportunities of years past and my first three choices have none at all. That changes with this pick. Home Depot (HD) is distributing a 3.09% yield.

It's getting tiring to relate the demise of various companies to the residential market collapse, high unemployment and so forth, but certainly this company has been greatly affected. In addition, Home Depot was already struggling to recover from a "me first" CEO who happened to be forced out with the small stipend of $200 million, leaving behind shabby stores with questionable customer service while at the same time facing strong competition from Lowe's Cos (LOW).

Where as my fist pick, Berkshire Hathaway (BRK.B) is a large cap diversified conglomerate, my second, Grubb & Ellis Co. (GBE), is a micro-cap stock of $90 million.

GBE is a network of nearly 130 owned and affiliated offices, providing commercial real estate services to property owners, institutional investors, and tenants. Its 1,800 brokers and some 6,000 affiliated real estate professionals offer advisory and brokerage, property management, construction consultation, and other services.

The company has been devastated by the bursting of the residential real estate market bubble, lost equity value, illiquid capital markets and the still impending concern over the commercial real estate market facing rising vacancies as hundreds of billions of dollars in loans must be rolled over.
