I've just returned from the World Money Show in Orlando where more than 10,000 investors gathered to learn about global investing. I had a chance to meet with many of the U.S. and foreign financial experts featured at the show, and over the next week I will share some of their top investment ideas. To view all of the stocks featured in this special global report, click here.

As an advisor, scientist, and venture capitalist, Josh Wolfe is a recognized leader in nanotechnology; in fact, he was among a handful of industry experts invited to join President Bush in the Oval Office when he signed the landmark nanotech funding bill.

The ideas that he recommends are often meant for the more-sophisticated investor, as can be seen from his latest global nanotech idea -- Oxonica (LSE:OXN), a London-listed nanotech firm. Intriguingly, he speculates that the company may soon list its shares in the U.S.

The editor of The Forbes/Wolfe Nanotech Report explains, "Oxonica, which supplies nanomaterials for the energy, security, health care, and materials sectors, appears to be bucking the trend. Spun out of Oxford University in 1999, Oxonica has already established itself as a leading nanotech start-up.

"Recently, it was rated as a top start-up for corporate partnership by nanotech strategic advisory firm Lux Research." For full disclosure, he notes that his venture firm Lux Capital is an equity investor in Lux Research.

Meanwhile, he notes, "The key to Oxonica's success has been its portfolio management approach to commercializing nanomaterials. Oxonica has products in its pipeline for industries as diverse as cosmetics, energy, security, and bio-diagnostics and it has not restricted itself to being a one-trick pony.

Each year Steven Halpern, editor of TheStockAdvisors.com, surveys the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is part of his 24th annual Top Stocks Report.

Symyx Technologies (NASDAQ: SMMX) is the top speculative pick for 2007 from nanotech expert Josh Wolfe. The editor of the Forbes/Wolfe Nanotech Report says, "Santa Clara, California-based Symyx is one of the nanotech materials companies in our model Nanosphere portfolio.

"SMMX is a research services company focused on serving the chemical, energy, pharmaceutical, and electronics industries. It works closely with alliance partners ExxonMobil and Dow Chemical to provide research services, develop and sell discovery tools systems, and license software and intellectual property.

"We believe that the biggest source of value in Symyx is in spin-off opportunities. Two have, in fact, been funded by venture capital firms. In addition, materials that they are commercializing are now coming to market and will earn them royalties on top of the service and hardware revenues they already receive.

"For the four financial quarters ended September 30, 2006, Symyx generated $33 million in cash flow on revenues of $116 million. Revenues for the first nine months of 2006 were up 10% versus the same period in 2005. Symyx shares bottomed just below $20 in October of 2006."
