Although global expert Vivian Lewis believe we are not yet "at the end of the correction" she continues to find selected opportunities in individual stocks, such as Israeli-based Alvarion (NASDAQ: ALVR), a leader in WiMax technology.

In her Global Investing newsletter, the advisor says, "The market's recent rise was fed by a 'shortage' of stocks; without buybacks and private equity, there will be glut."

She forecasts that as borrowing gets costlier, it will dry up investment by the corporate sector, homebuilders and consumers. And, she cautions, fixed-income vehicles will then lure investors away from the stock market.

Nevertheless, she continues to recommend select special situations, and has added Alvarion to her buy list. She explains, "WiMax started out as the commnications standard of the Israeli Army in desert campaigns, but is now widely used in countries where telephony is in its infancy, in the developing world."

Now, she says, "Alvarion's all-IP OPEN WiMAX ecosystem opens the door to complete, best-of-breed networks." She explains, "Through a new technology arrangement with ArrayComm's Advanced Multi-Antenna software, the company will be able to offer fast personal broadband network services and take this around with them."

She explains, " This will be a kind of 'always-on' IP-based service for high speed broadband. This will do email, computing, telephoning and texting, games, other consumer electronics, media, office, whatever. Another way to name it is 'DSL on the move'. We rate the stock a buy."

Last December, over 100 stocks were featured in our Top Picks for 2007 report. Now, at mid-year, we turn to the 20 advisors whose picks showed the strongest gains to get an update on their previous picks, as well as a new favorite stock for the second half of the year.

Vivian Lewis, editor of Global Investing, chose DryShips Inc. (NASDAQ: DRYS) as her top pick for 2007. The stock rose 126%, as of June 1, 2007. Here is her original recommendation on DRYS and her new favorite stock for the rest of 2007.

Meanwhile, the advisor now says, "DryShips is trading at a P/E of only 15, even now that the stock has gone up 300%. There is a lot of negativity about George Economou, who heads the company and now is the CFO.

"He headed a prior shipping company, which filed for bankruptcy after it could not pay back loans to British banks a decade ago. This was in the DryShips prospectus of course, and was also the subject of a report written by Kate Welling (former Barron's reporter) for a group shorting DRYS, including the Weeden brokerage firm.

"As a result, all this maybe makes DRYS cheaper than in would be otherwise. When I recommended DRYS in Global Investing in December 2005, I wanted it for its yield of 7.8%. That went up to 8.4% a year ago when the shorts were out in force, and the stock fell from $12.75 (our buy level) to $9.50.

"So the recovery is nice, but there is still an 'odor' around, which is why the resignation of the second CFO in a year causes some upset. I'm not giving up on this stock and indeed, perhaps would want to buy on weakness -- although as a holder, I am not sure I want to see weakness."

Last December, over 100 stocks were featured in our Top Picks for 2007 report. Now, at mid-year, we turn to the 20 advisors whose picks showed the strongest gains to get an update on their previous picks, as well as a new favorite stock for the second half of the year.

Vivian Lewis, editor of Global Investing, chose DryShips (NASDAQ: DRYS) as her favorite stock for 2007, which rose 126% as of 6/1/07. Here is her original recommendation on DRYS and her current opinion on the stock.

Now, she explains, "For a new pick for the second half of 2007, how about a copper company from Canada reviving an old mine in Baja California, Mexico?" Baja Mining (TSE: BAJ) is her current strong favorite.

"Baja Mining got a definitive feasibility study of its Boleo Project in Mexico, and it is lovely. Based on a presumed copper price of US$1.50/(metric) tonne, and cobalt at $15/pound and zinc sulphate at $1,200/tonne, the average cost of produced copper, net of byproducts, would be minus 7 cents/lb.

"Proven and probable reserves are sufficient for a 25-year mine life, with 275 million tonnes of measured and indicated resources grading 1.77% copper equivalent, and a further 250 million of inferred resourced grading 1.29% copper equivalent.

"These huge reserves mean that the project will have an after-tax indicated rate of return of 24.7%, or 46% at current market prices for the metals. The net project value at an 8% discount rate is $700 million, or $2.3 billion at current market prices.

Having just completed the Top Picks report for 2007 – the 24th consecutive year I have surveyed the newsletter advisors for their favorite stocks -- I thought I would share some observations to help readers best use the information in this feature.

And over the next few days, I will post articles to share observations on the stocks and sectors chosen, discuss the participating advisors, and highlight some of last year's top performers to help guide you in assessing this year's report.

I'll begin today by noting some caveats that should be kept in mind by those who are considering buying stocks from among the list of Top Picks. The advisors who have participated in this year's project were asked to submit a favorite speculative and/or conservative stock for the year ahead.

DryShips Inc. (NASDAQ: DRYS) is the top speculative idea for 2007 from Vivian Lewis, editor of Global Investing. She notes, "The company is an operator of a drybulk cargo fleet, and produced no more negative surprises with its unaudited financial and operating results for the third quarter.

"True, there was a net loss of $9.4 million (a loss of 28 cents per share) from Forward Freight Agreement losses previously announced. They were made by the now-fired CFO early in 2006. He disastrously misjudged the drybulk charter rates trend.

"His replacement, Gregory Zikos, a lawyer, MBA, and investment banker, has just been named CFO and to the DRYS board. Meanwhile, Cantor Fitzgerald reiterated a 'buy' on DRYS, forecasting 2006 earnings at $2.24 and 2007 at $2.15, below earlier estimates but with more confidence. Cantor's target is $16.

"Apart from these losses, the rest of the quarter was within the norms of highly leveraged Greek shipping companies, and net income in the quarter would have been 50 cents per share.

"Meanwhile, Dryships' major shareholders (led by George Economou) reinvested the 20 cent per share dividend payment they were scheduled to receive in October, in the amount of about $3.1 million, in DryShips shares. For speculative investors, we consider the stock a strong buy."

Osaka, Japan-based Chris Loew -- who covers Japanese stocks for Global Investing -- picks both his speculative and conservative favorites for 2007 from the same consumer trend. He explains, "In the apparel sector, fur is huge this year. The must-have item in Japan this winter is a down coat with real raccoon or tanuki (raccoon-dog, fox family) fur trim on the hood (priced about $250).

"Sanei International Co., Ltd. (JP:3605) (Other OTC SNEIF) -- my conservative pick for 2007 -- owns a multitude of apparel brands, mainly for women, and operates 1,088 stores and is well positioned to profit from this frenzy.

"The stock is reasonably priced at a P/E around 15 to17, barely reflecting improved consumer demand this year. In '07, the real-fur trend and looser consumer spending should give Sanei shareholders a warm feeling.

Canadian Oil Sands Trust (TSX: COS.UN) is the top conservative buy for 2007 from international investing expert Vivian Lewis. The editor of Global Investing notes, "Canada recently slapped surprise taxes on income trusts. Nevertheless, we think oil sands will also be a good idea even if not exempt from taxes on dividends.

"The main reason is that the dividends are pretty meager. COS pays 2.7%. This is not going to cause a sell-off in the share, even if the dividend is cut in 2011. The trust, however, dropped 10% in what I consider a mistaken reaction to the tax news.

"Meanwhile, Canadian Oil Sands Trust saw third quarter volumes and sales prices rise, which partly offset higher royalties paid, while net fell 27%. The dividend is 30 cents per unit. The stock is up 41%, including dividends, over the past year.
