A strong run of earnings reports today, along with a somewhat influential analyst note, are taking energy stocks higher in today's trading session.

The oil and gas sector and the coal group both enjoyed gains. The

Dow Jones U.S. Energy Index

picked up a small gain of 0.2% by the afternoon, as oil and gas rode into the green on this morning's positive earnings reports from

Enron

( ENE) and

Dynegy

(DYN)

. Those results came on the heels of

Reliant Energy's

(REI) - Get Ring Energy, Inc. Report

earnings report yesterday, and all three companies beat analysts' estimates.

Reliant posted first-quarter earnings of 72 cents a share, topping the consensus

Thomson Financial/First Call

estimates of 70 cents. The strong first quarter, plus an adamantly positive outlook for the future sent the stock up 3.6% to $48.68. Enron, which also posting earnings well above estimates, reported a bottom line of 47 cents a share. Estimates came in at 45 cents. Enron was trading up by 2% to $60.64.

Dynegy, which posted net income of 41 cents a share, surpassed the consensus forecast by a penny, and the stock rose 4.6% to $55.58.

The Dow Jones U.S. Gas Utilities Index

is up 0.4% today, while the combination

Dow Jones U.S. Oil & Gas Index

rose 0.1%.

"As a group, I think

oil and energy stocks are going to do well for the long-haul," said Doug Myers, vice president of trading at

IJL Wachovia

. He added that he wouldn't be surprised if in the near-term the market saw a "nice 10% jump across the board" in energy stocks.

The

Amex Natural Gas Index

TheStreet Recommends

rose a little more than 1% on today's earnings news, while the

Chicago Board Options Exchange Oil Index

slipped 0.1%.

Other well known names in the sector are slightly mixed in performance.

Chevron

( CHV), an integrated petroleum company, lost 50 cents to $93.30. Oil services company

Schlumberger

(SLB) - Get Schlumberger NV Report

, posted a gain of 0.6%.

Lifting the coal side of the larger energy sector was a note put out this morning by

Lehman Brothers

analyst Peter Ward, who initiated coverage of

Massey Energy

( MEE).

Ward, an energy and power analyst, tacked a buy rating on the coal producer, noting that "fundamentals for low-sulfur coal have never been better. In the past few months, the coal market has reversed a 20-year trend and become a sellers' market." Those seemed like just the right words to send Massey's stock up to a 52-week high of $25.30, before the issue settled back to $25.15. Massey, currently the sole component of the

Dow Jones U.S. Coal Index

, sent the index on the same ride.

Ward also issued a notes on competitors

Arch Coal

(ACI) - Get Albertsons Cos. Inc. Report

and

Consol Energy

(CNX) - Get CNX Resources Corporation Report

, raising Arch's estimates. "Frankly, Arch is a better pick" than Massey, Ward said in a telephone interview. Arch was recently up $1.37, or 3.9%, to $35.15.

As commodity indexes show prices on the rise since the start of April, Myers noted that "the end-users are going to have to pay substantially higher prices for their energy use," citing the recent problems in California as one specific example. As a result, he sees "increased space for better margins."

Since the start of April, the Dow Jones oil, gas and energy indexes have each been on a steady rise.
