During Thursday's trading, Anadarko Petroleum (NYSE: APC) hit an all-time high of $78.75 and closed at $77.62. Anadarko was one of my first recommendations after I started writing for BloggingStocks, and is nearing 100% appreciation from the $40 price tag it had when we acquired it.

The 10-year chart below indicates the strong long-term performance of Anadarko, rising about 500% and paying dividends to boot. I cannot say the stock is a bargain at recent highs, but I can emphatically state that this company belongs on your watch list.

Watching one of your largest holdings go up in value is a vision of joy. The same is not true on the way down. Huaneng Power ADS (NYSE: HNP) is indeed way down from its high of $57.50. I recommended the stock last year at $26.50 and looked brilliant until last month when it completed retracing its upward trajectory back to that level.

The company reported an 80% drop in earnings attributed to higher coal costs Tuesday. However, today the value buyers must be back in droves because the stock closed up almost 16% as one of the day's big movers. The stock closed at $30.25, up over $4 per share. The following three-year chart captures the drama.

The Dow Jones Industrial Average is down about 150 points as I peck away on my laptop. I was looking to see what stocks were holding up on a down day, and sure enough one of my favorites showed up -- Precision Drilling Services TR (NYSE: PDS), a stock I recommended two months ago.

I apologize if I seem like a cheerleader, or a play-by-play announcer, but it was only two weeks ago that I posted on what were already strong gains, and this one keeps going up (even though its business is to drill down...). From my original December recommendation at $15.47 per share, PDS has moved up to $22.61 by midday today and climbing, for a 46% gain. This is when the Dow industrials are down almost 7%.

Two super companies reported earnings this afternoon, both with a heavy burden to outperform. One did, one did not. Intuitive Surgical, Inc. (NASDAQ: ISRG) after the market close announced $189.4 Million Fourth Quarter Revenue, Up 68 while reporting earnings of $1.24 per share besting analysts expectations of $1.04 by 19%. In after hours trading it is up $36 per share as I peck away on the keyboard, up to $289 after already rising $19.00 during the trading day. My last post on the subject was Chasing Value: Intuitive Surgical drops 12% today.

Google, Inc. (NASDAQ: GOOG) on the other hand, while reporting positive growth, fell short of analysts expectations by 2% and you know what that means: a reversal of fortune and headlines like Google Shares Plunge After Earnings Miss. The Stock closed the day up $16.03 to $564.30 only to take a dive in after hours trading almost $40 per share. Tomorrow will be another day and those wiser than I can dissect the company report further, along with market sentiment. However, Google has been down with the market all month long and there is enough fear in the market to prevent any notable stock recovery this year, unless the perception of internet advertising shifts again.

Well today I lost some cash, at least 'on paper.' And if I believe what I read in the business news it is because of the comments of a single analyst. Now that's power. It has to make you wonder. Intuitive Surgical (NASDAQ: ISRG), one of my biggest holdings, finished the day at $244.30 down $33.27. OUCH!

Shares of medical device maker Intuitive Surgical Inc. fell sharply Tuesday as an Oppenheimer & Co. analyst said the company's strong growth will slow in 2008 on fewer U.S. sales of the da Vinci surgical system, due to market saturation and a lack of adoption by gynecologists for hysterectomy procedures.

Analyst Amit Hazan said Intuitive Surgical is the most expensive stock in the medical technology sector, a value driven by both the company's robust growth rates and by results consistently beating Wall Street expectations by wide margins. He is correct that ISRG is expensive. Even after todays losses it still is trading at a P/E ratio of about 80.

Despite reporting a 49% drop in fourth quarter earnings, Valero Energy Corporation (NYSE: VLO) beat Wall Street expectations by 38 cents, and you know what that usually means -- the stock jumped.

Valero was able to take advantage of price spreads on crude in the fourth quarter that were obviously not a part of analysts' estimates which they are no doubt changing as we speak.

According to the AP: "In 2008, Valero officials said they expect gasoline markets to return to more seasonal patterns, with margins improving during the summer driving season. Diesel margins were expected to be strong because inventories are lower than last year and demand remains strong, said Chairman and CEO Bill Klesse."

What can I say except to report the facts as they are. Valero Energy (NYSE: VLO), one of my top picks of 2007, is my worst of 2008 -- so far! The refiners have taken a big hit this year as the Department of Energy has reported that gasoline inventories are up at the same time that oil prices have only come down marginally.

This is putting the squeeze on oil refiners like Valero, which are not able to increase margins on slackening demand at the pump. Last year, Valero made me look great all year long, rising 36%, and this year I stuck with it: Chasing Value: Valero Energy (VLO) is just so refined.

If the economy continues to look gloomy and the inventory trend continues, with supplies remaining more than ample, then perhaps my best pick will turn into my worst.

In the meantime, we are only 10 days into the new year, and January has been dismal. The market was up and down yesterday, finally ending higher, as fickle as I have seen it in a while, and it is up notably again today. Valero closed yesterday at $61.67, about $8 off my start point. It is up today even after the inventory report has been broadcast, so I think fickle is the word of the day, or even the week.

This is the final review of the seven stocks I picked twelve months ago, and the time has passed quickly. This covers the period from December 28 2006 through December 27 2007. It has been a stock pickers year for sure given that the S&P 500 index moved up only modestly. Having come to this conclusion, I must admit my seven picks were all over the place. Three beat the indices, two performed sorely and two were basically break even except for the healthy dividends.

If the stock you happened to pick was Google, Inc. (NASDAQ: GOOG), which I included as sort of a "stalking horse" because of its popularity, it beat all else as a portfolio of one. As a matter of fact GOOG beat my picks by a whopping 930% meaning it bested my returns with very little effort with a gain 9.3 times the average of my seven stock picks.

The average of my seven picks fell dramatically in the last two months and I have gone from wonderboy with about a 22% YTD return, to waterboy with about 5.5% return -- UGH! I rode the Chinese market up and down, among the macro events.

Luckily for me I did not stop picking stocks last December. My actual average of all recommendations in 2007 is notably higher, see: Chasing Value: My best and worst picks of 2007.

Highlighting the fact that this year was suited to the stock pickers, James Cramer's average based on his nine picks beat all the indices by a healthy margin. Cramer, as you might imagine, had the most volatile picks. The two best Apple Inc. (NASDAQ: AAPL) and Savient Pharmaceuticals Inc. (NASDAQ: SVNT) did spectacularly well. Apple was appreciating most of the year while Savient saved Cramers tush by doubling in the last month due to approval of one of their drug therapies.

• Dow Jones Industrial Average: 12,501.52 is Up to 13,359.61 (+6.86%)
• NASDAQ Composite Index: 2,425.57 is Up to 2,676.79 (+10.36%)
• Standard & Poor's 500 Index: 1,424.73 is Up to 1,476.37 (+3.62%)

This was a close call for me, but in the end I decided I would only include one power company on my stock list for 2008, and this was not it. I recommended Duke Energy Corporation (NYSE: DUK) last year and wrote about the company numerous times.

Duke pays a handsome dividend yield of 4.29%, and will likely see some growth next year as investors look for stability. This year it was relatively flat. That might be good enough if the market ends in turmoil next year, but I expect it to trade below the Dow Industrials even if it trades ahead of the Standard & Poor's 500 Index.

If you are just starting out and building a new portfolio for the long term, Duke Energy is definitely a good conservative beginning. It would be in my top 20 picks, but it just got crowded out of my list of eight. DUK had a closing price of $20.56 Wednesday.

DISCLOSURE: We own shares of DUK in several portfolios. We bought in between $18 - $19 a share for a long term hold.

Hey, I admit that I am infatuated with this company and the guy who runs it, Warren Buffett, I just think it has had a good run and I am a watcher at this point, not a buyer. Berkshire Hathaway Inc. (NYSE: BRK.B) was a strong candidate for inclusion on my 2008 buy list, but today is not the day.

I have written volumes about why BRK.B should be included in new portfolios and is a must on every watchlist, but I just do not see it as the bargain I did when I was promoting it at the $3,600 level. Although it does not pay a dividend, most of its stock holdings do, and Warren Buffett has been the gold standard for creating shareholder equity. If 2008 proves to be a shakey year on Wall Street, you may want to own this stock. That however, will be a reflection of the economy more than stock value.

This week it was announced Berkshire Hathaway executed a $4.5 billion buyout of Marmon. Berkshire has done a lot of buying this year. One example being its 8% stake in Burlington Northern Santa Fe (NYSE: BNI) railroad, reportedly now the largest shareholder. At the same time it has been selling other positions and completed its exit from PetroChina Co LTD ADR (NYSE: PTR) prior to a major pullback in Chinese stocks. Berkshire recognized huge gains from this sale, and it is reflected on the company's bottom line.

My eight stock picks for 2008 will not include one of my favorites, Intuitive Surgical, Inc. (NASDAQ: ISRG) because of recent appreciation in the stock price. Since I am basing my picks on the December 28 close, in two days, it just looks too pricey. The company is not only the leader in producing patented robotic surgical systems; it is the only game in town.

Intuitive Surgical was a strong candidate at $280 to $290, about 20% off it's high, but not at Wednesday's closing price of $335.24. It has a trailing P/E of 109 and a forward P/E of 77 if you believe projections, and I do since ISRG is constantly beating them. However, this stock has a 52-week low of $86.20 and a high of $359.59. That's very high and a 400% bounce has to leave even Apple Inc. (NASDAQ: AAPL) and Google Inc. (NASDAQ: GOOG) enthusiasts astonished.

I have written favorably about ISRG in the past 22 months, so perhaps some of my readers have shared in the gains. It is one of the few stocks I have mentioned that does not pay a dividend, but it has beat all estimates every year since I bought it, and is likely to do so again (albeit with fits and starts). It has hardly penetrated its potential market, and already it has grown into a $12 billion company.

At this point, I would definitely put ISRG on my watch list, and perhaps like many volatile stocks, there would be an opportunity to own it at a lower price.

Disclosure: I own shares of ISRG in several portfolios.

The headline story in Barron's (subscription required) this week "Sell Buffett" may have created a buying opportunity! I thought that the story by Andrew Barry was a very fair analysis. However, since I wrote Chasing Value: Berkshire Hathaway did what it's supposed to do -- go up! like Barron's, calling attention to Berkshire Hathaway (NYSE: BRK.A)'s stock rise and suggesting investors put it on their watch list waiting for a pullback -- Barron's might have triggered just such a slip.

In Barron's story, they make the case that fair value for BRK.A is probably around $130,000. It was $142,400 at the time of publication. The article suggests Berkshire is overvalued by at least 10%. Guess what, today the BRK.A shares are trading around $133,000, down about 9%.

When I wrote a week before the Barron's story came out, I suggested the same thing they did, but unlike Barron's, I felt that if it came down it would be worth buying, not because it was set to jet in the near future, but because a 10% to 15% pullback gives you the opportunity to add one of the most solid companies in the investing universe to your core holdings at a time when the market is very erratic, and oil, gold, interest rates, food, energy, housing, etc. is in turmoil.

In seeking value stocks that have seen their share prices greatly diminished this past year based on reduced earnings, I came across Precision Drilling Trust (NYSE: PDS), which has a price earnings ratio (P/E) near 5 and a dividend yield over 10%. According to AOL Money & Finance information the company is Canada's largest drilling contractor with a fleet of 240 service rigs. Its contract drilling units provide drilling services, equipment supply and repair, and on-site catering and management. PDS has extended their reach into the United States this year and has invested in new technology, replaced older rigs, and is preparing for continued expansion. Favorable metrics include a low P/B of 1.57 and high historic profit margins of 40%.

PDS closed today at a price of $15.47 per share near its 52 week low of $15.35, a low set today during the trading day, and 44% off its high of $27.78. The P/E is a trailing figure and is actually higher but the dividend looks secure. The dividends have been paid monthly. The company earned $0.58 for the third quarter implying an annual return of $2.32 if earnings do not slip further. That would give it a forward P/E of 6.68. This is comprable to other energy sector stocks, unless earnings are further eroded. The winter weather makes working PDS's drilling rigs harder. I am looking for the spring thaw to also thaw out its earnings.

When I posted Chasing Value: Newcastle's 21.9% yield too good to be true?, I said that the metrics don't really matter as long as Newcastle Investment Corp (NYSE: NCT) stays open for business and keeps paying that dividend!

Today came the announcement that NCT will be distributing $0.72 per share for the fourth quarter, on January 30, 2008, to shareholders of record on December 31. This represents a 20% dividend yield -- not too shabby, but a little lower based on today's price, hovering around $14.00. When I first posted, the stock was 10% lower and yield was 10% higher.
