David Fried has developed an industry-leading reputation by focusing on companies buying back their shares. Here, his Buyback Letter looks at EnCana Corp. (NYSE: ECA).

"Canadian oil producer EnCana is among the largest holders of oil and gas resource lands in onshore North America, has an extensive drilling inventory with some 40,000 well locations, strong production and reserves growth, and robust project returns. It is focused on natural gas and in-situ oil sands.

"As the dangers of global warming have become more apparent, major energy companies are attempting to capture carbon dioxide and lock it away where it won't trap more heat. Industry leader EnCana has embarked on a pilot project to improve recovery rates from mature oil wells by using carbon dioxide.

"EnCana buys carbon dioxide produced by a power plant and ships it via pipeline to its Weyburn field in southern Saskatchewan. EnCana injects the gas into its oil field, where it reduces the viscosity of the oil, allowing the company to increase its recovery from the field.

What are the best energy investments for long-term investors? To answer this question, I surveyed 20 of the nation's leading financial newsletter advisors to find their current favorite ideas in the energy sector.

Interestingly, the advisors see the best opportunities in areas well beyond traditional oil firms; indeed, no one included in this report chose a major integrated oil company. Rather, the advisors have shown a preference for various oil services sectors, non-oil energy sources, and developing alternative technologies.

Some focus on areas such as deep-sea operations with Diamond Offshore Drilling Inc. (NYSE: DO), Transocean Inc. (NYSE: RIG) and Oceaneering International (NYSE: OII), while others look toward oil shippers such as Nordic American Tanker Shipping (NYSE: NAT) and refiners such as Valero Energy Corp. (NYSE: VLO).

Others chose companies that make specific products needed by the oil & gas industries such as NATCO Group Inc. (NYSE: NTG), which makes a wide range of oil & gas processing systems; Dresser-Rand Group Inc. (NYSE: DRC), a maker of control systems; Gardner Denver Inc. (NYSE: GDI), which makes compressor and fluid transfer systems; Tenaris (NYSE: TS), a maker of pipes and tublar products and Schlumberger Ltd. (NYSE: SLB), the largest and most diversified of the oil services companies.

Got gold? In this edition of StockWatch: Between the Bells, Thomas Winmill of the Midas Funds outlines his strategy for broadening your portfolio with investments in precious metals and foreign energy concerns.

Echoing the sentiments of recent StockWatch contributors, Tom says we're currently in a bull market, and can expect growth to continue, thanks in part to recently lowered interest rates.

Tom recommends investors check into foreign equities -- he favors overseas energy companies like Hong Kong's CNOOC (NYSE: CEO), and EnCana Corporation (NYSE: ECA) of Canada. CNOOC manages China's offshore oil and gas exploration, and currently traded in the $160s, gushing up from around $100 in mid-August. EnCana is one of North America's largest oil and gas distributors, and trades about $20 higher than at the start of 2007.

Tom also urges investors to look beyond stocks and bonds, and suggests devoting between five and ten percent of your portfolio to gold and other precious metals.

This morning I posted on five stocks that might be worth buying in New York society doyenne, Brooke Astor's $23.5 million portfolio of 15 stocks. But with Spring finally sprung, which ones should she clean out of her portfolio?

This is the question a CNBC producer posed to me after reading the Astor post. I'll be appearing tonight at 7:15pm with Melissa Francis's On The Money. Here are the three stocks I would clean out of Brooke Astor's portfolio:

• Encana Corp. (NYSE: ECA), the Canadian gas producer, is overpriced given shrinking earnings expectations. ECA had $16.4 billion in sales -- up 16% -- and $5.1 billion in profit -- down 66% -- in the last year. Its earnings are expected to decline 7.8% to $4.01 next year and its P/E of 8.6 seems high given the earnings decline. Encana has a dividend yield of 1.6% and it rose 4.3% in the last year.
• XTO Energy (NYSE: XTO), the Texas oil and gas producer, is also overpriced given shrinking earnings expectations. XTO had $4.6 billion in sales -- up 30% -- and $1.9 billion in profit -- down 5% -- in the last year. Its earnings are expected to decline 0.4% to $4.55 next year and its P/E of 10.9 seems high given the earnings decline. XTO's dividend yield is 0.89%.and it rose 4.3% in the last year.
• Morgan Stanley (NYSE: MS), the investment bank, is pricey given its low earnings growth expectations. MS had an explosive 2006 -- with $83.2 billion in sales -- up 47% -- and $8.4 billion in profit -- up 59%. Its earnings are expected to rise a mere 3.8% to $8.18 next year and its P/E of 10.1 yields a lofty PEG ratio of 2.65. MS has a dividend yield of 1.33% and it rose 29% in the last year.

Of the three, MS is Astor's biggest holding and if its earnings exceed these low expectations the stock could do quite well. But given all the uncertainty in the mortgage markets -- to which MS is exposed -- I'd suggest Astor lighten up on MS as well.

MOST NOTEWORTHY: Best Buy (BBY) and Oracle (ORCL) were today's most notable downgrades:

• William Blair downgraded Best Buy Co. Inc. (NYSE:BBY) to Market Perform from Outperform, expecting a slowing down in growth from advanced TV, a difficult competitive environment and cyclicality of consumer electronics spending in 2007;
• First Albany downgraded Oracle Corp. (NASDAQ:ORCL) to Neutral from Buy, citing valuation and a likely slowing down in growth within two-to-three quarters.

OTHER DOWNGRADES:

• Baird downgraded Forward Air Corp. (NASDAQ:FWRD) to Neutral from Outperform, citing weak near-term truck freight trends and economic uncertainty.
• EnCana Corp (NYSE:ECA) was downgraded to Sell from Hold at Citigroup to reflect the disappointing 2007 guidance with 1% overall production growth, as well as cost run-up and concerns of portfolio quality.
• Following poor second-quarter earnings and light third-quarter guidance, Baird downgraded Tektronix Inc. (NYSE:TEK) to Neutral from Outperform and a $33 target.
