Analyst initiations:

MOST NOTEWORTHY: Golar LNG, Yingli Green Energy and Bill Barrett were today's noteworthy downgrades:

• Jefferies downgraded shares of Golar LNG (NASDAQ: GLNG) to Hold from Buy on valuation, as they see limited upside over the next 12 months.
  
• Banc of America downgraded shares of Yingli Green Energy (NYSE: YGE) to Neutral from Buy on difficult fundamentals, as they believe solar industry gross margins will continue to contract due to silicon competition and decelerating demand in Spain and Germany.
  
• SunTrust lowered Bill Barrett Corporation (NYSE: BBG) to Neutral from Buy based on valuation and lack of near-term exploration catalysts.

OTHER DOWNGRADES:

• Autodesk (NASDAQ: ADSK) was lowered to Accumulate from Buy at ThinkEquity.
  
• Goldman removed Oneok (NYSE: OKE) from its Conviction Buy List.
  
• Merrill Lynch downgraded Boardwalk Pipeline Partners (NYSE: BWP) to Sell from Buy.

ONEOK (NYSE: OKE) purchases, transports, stores and distributes natural gas in the United States. The firm's ONEOK Partners segment is engaged in the fractionation of natural gas liquids and the gathering and processing natural gas, primarily in the Mid-Continent and Rocky Mountain regions. The Distribution unit provides natural gas distribution services to residential, commercial, and industrial customers in Oklahoma, Kansas, and Texas. The Energy Services operation focuses primarily on marketing natural gas. ONEOK sold its gathering and processing, natural gas liquids, pipelines and storage businesses to ONEOK Partners in 2006 and became that company's general partner and 46% owner.

The firm pleased investors last week, when it boosted its FY07 EPS guidance from $2.62-2.72 to $2.75-2.79. The Street had been looking for $2.66. Management also issued FY08 guidance of $2.75-3.15 ($2.87 consensus). OKE shares popped on the news and then moved into a bullish "pennant" consolidation pattern. Prices frequently exit pennants moving in the same direction they were traveling on entry. In this case, that would be to the upside.

Brokers recommend the shares with two "strong buys", one "buy" and six "holds". The OKE P/E ratio (19.83), Price to Sales ratio (0.40), Price to Book ratio (2.66), Price to Cash Flow ratio (7.40), Price to Free Cash Flow ratio (28.53) and Revenue per Employee ($2.77M) compare favorably with industry, sector and S&P 500 averages. Institutions hold about 74% of the outstanding shares. The stock is one of those used to calculate the S&P 400 MidCap Index. Over the past 52 weeks, it has traded between $39.26 and $55.27. A stop-loss of $42.00 looks good here. Note that the firm is expected to report Q4 results on February 25th, after the closing bell.

Oklahoma turns 100 years old this year, and I wrote a bit about its business climate in my recent Investing in Oklahoma post. That post featured some growth companies based in Oklahoma: Arena Resources Inc. (NYSE: ARD), Helmerich & Payne Inc. (NYSE: HP), Unit Corp. (NYSE: UNT), Chesapeake Energy Corp. (NYSE: CHK), ONEOK Inc. (NYSE: OKE), Devon Energy Corp. (NYSE: DVN), and the Williams Companies (NYSE: WMB).

Earlier this year, the Motley Fool also took at look at Oklahoma companies, and focused on some of the same energy sector companies that I did. Its search also included two non-energy companies as well: drive-in burger chain Sonic Corp. (NASDAQ: SONC) for its growth potential, and Tulsa-based Dollar Thrifty Automotive (NYSE: DTG).

Sonic recently announced 21 consecutive years of positive same-store sales performance, and reaffirmed its 33 cents earnings per share earnings expectations for the fourth quarter. For fiscal 2008, Sonic expects earnings growth of 15% to 17%. The consensus of analysts surveyed by Thomson Financial is that Sonic is a buy. The share price was $23.40 at the close on Friday, up from a 52-week low of $20.02 in late July, not yet quite back to its 52-week high of $25.09 in May, but still up from its stumble at the end of August after an analyst's downgrade based on labor and dairy costs. That was before the announcement and reaffirmed expectations mentioned above. Also, Sonic made the Forbes list of 100 best mid cap stocks in America.

Oklahoma celebrates its centennial in November -- Happy Birthday, Oklahoma!

Today, Oklahoma is known as one of the most business-friendly states, due in part to low tax rates. Oklahoma's economy is based largely on the energy, aviation, and food processing sectors. From 2000 to 2006, Oklahoma's gross domestic product increased 50 percent. The GDP per capita grew almost 10 percent between 2005 and 2006, one of the highest rates in the nation.

Fortune magazine's 2007 list of the fastest growing companies in the U.S. included six from Oklahoma. At number three on the list was Tulsa-based Arena Resources Inc. (NYSE: ARD), a seven-year old oil and gas firm with a three-year annual growth rate of 165 percent. Back in August, Arena announced strong second quarter 2007 financial and operating results. Arena is also a major holding in the Bruce Fund, which recently made the 2007 Forbes Honor Roll.

Tulsa-based oil and gas driller Helmerich & Payne Inc. (NYSE: HP) had a three-year annual growth rate of 37 percent, which beat the S&P 500. In August, H&P announced strong second quarter 2007 results, as well as two new contracts. The Motley Fool sees expansion in other sectors as good news for drillers such as H&P.
