IdaTech, an Oregon fuel-cell company will bypass the New York stock markets, Nasdaq and the NYSE, and list on the London Stock Exchange. The flotation is valued at £100m ($195m).

Observers believe this is another sign that America’s draconian Sarbanes-Oxley legislation is proving a turn-off for U.S. firms.

IdaTech manufactures environmentally friendly generators for industry and for recreational use. Owner Investec, with 96 percent of the stock, is selling between 50 and 60 percent of its holdings.

Following Nasdaq’s £1.9 billion ($3.7bn) deal to buy Swedish exchange OMX, which operates in Iceland, the Baltic states and Scandinavia, Dubai has muscled in on the act.

The Dubai International Financial Centre is said to be “the world’s newest international financial centre”. It has appointed HSBC to advise it on a possible challenge for OMX.

On Friday, OMX agreed to be taken over by Nasdaq, the New York exchange, which last year made two failed attempts to buy the London Stock Exchange.

The Nasdaq cash and share deal for OMX would have created a £3.8 billion ($7.5bn) company with operations in eight countries. It would be the third transatlantic merger between exchanges in the past 12 months.

The Times (London) reports, “The DIFC’s decision to consider a counterbid further underlines the international ambitions of the tiny Gulf state. Last year, Dubai Ports World, another arm of the Dubai government, seized control of some of the world’s most important ports when it acquired P&O. The planned bid for OMX signals DIFC’s ambitions to raise Dubai’s profile in international financial markets.”

The Dubai International Financial Exchange, which opened for business in 2005 was intended to “create an environment for progress and economic development in the UAE and the wider region”.

So, the consolidation of the world’s stock markets proceeds apace. In March the New York Stock Exchange completed its acquisition of Euronext, the pan-European borse. Nasdaq claims still to have ambitions to bid for the LSE, but is prevented by City regulations from bidding again until next February.

A combination of OMX, which is being advised by Credit Suisse and Morgan Stanley, and the slightly larger Nasdaq, being advised by JP Morgan, would create a company worth 30% more than the LSE, which has a market value of £2.7 billion. OMX has a derivatives business that ranks behind NYSE Euronext’s Liffe, and Eurex, controlled by Deutsche Börse. It is considered particularly attractive by other exchanges because of its innovative financial-trading technology.

Nasdaq is planning to use new generation OMX technology as a base for the group, which would, it claims, deliver two-thirds of the £76m ($150m) that may be gained from the merger.

Dubai, however, might just have the last word.

With Robert Greifeld identifying three key areas of interest for Nasdaq in the next year, a renewed bid for the London Stock Exchange seems likely. The areas are :

* Taking market share from NYSE Group.
* Fending off BATS, a new electronic stock market.
* Forging mergers and acquisitions.

It is then anticipated that Nasdaq will make a new attempt to take over the LSE before the end of the third quarter of next year.

The LSE has declined to comment on Nasdaq’s position. In return, it ratcheted up takeover rumours by claiming that it’s looking at its own “strategic alternatives”.

The Times (London) reports :

The New York market has been linked to takeover talks with both the Philadelphia Stock Exchange and the Nordic OMX market in the past week. It is understood that the talks with Philadelphia are advancing well and that Nasdaq insiders expect a takeover to be sealed within six months.

Talks with OMX, which has also tried and failed to take over the London exchange, are at a much earlier stage, but both potential deals are part of a wider strategy to boost Nasdaq’s balance sheet and improve its product offering, so that its next bid for the LSE will be more difficult to reject.

A Nasdaq insider commented, “The long-term objective is still London. This is a game of chess and LSE is the king.”

We await the new LSE moves with great interest.

The Chairman of the London Stock Exchange, Christopher Gibson-Smith, recently gave an interview to The Times (London) considering a number of possible outcomes for the business going forward.

In the wake of the comprehensive defeat of the Nasdaq bid, what threat is posed by the new giant forming across the water in Paris between Euronext and the New York Stock Exchange?

“What’s going to happen”, says Gibson-Smith? “I don’t suppose they know. We watch it really carefully, but it’s not a short-term threat.”

He also dismisses any increased competition arising from Mifid, the new EU directive on financial services, and the prospect of Project Turquoise, a rival trading platform from a consortium of powerful banks. Mifid, he says, offers more opportunities to the LSE than dangers, and more of a threat to continental rivals. “They have tried it before and not achieved it. They might this time. We don’t [believe they will]. We feel confident in being able to deal with it.”

The Chairman points out that the LSE is growing trading volumes by 55 percent a year driven by algorithmic trading, which allows business to be conducted electronically at high speed. “[The system] is transforming capacity to use our transformed market”, he says. “I see a world awash with opportunities.”

However, on global markets, he’s more cautious, “There are some real national barriers in the way of achieving that.” And will the NYSE/Euronext giant come gunning for the LSE? “It’s filling column inches, but …”

Philosophical to the end, Christopher Gibson-smith opines, “There have never been, in my entire business career, fewer than five huge uncertainties that have to be dealt with”.

Whatever happens, it’s obvious the Chairman of the LSE does not intend to be caught napping.
