The Linaburg-Maduell index is calculated with 10 principles -- such as whether the fund provides up-to-date, independently audited annual reports, or whether it provides clear strategies and objectives. It also gives points on whether the fund gives ownership percentage of company hodlings, total market value, returns and management compensation.

Enhancing transparency is a key task for sovereign wealth funds, whose often opaque operations have come under heavy criticism by some Western politicians who suspect them of investing with political, rather than commercial, motives.

In fact in the recent meeting of the world's leading sovereign wealth funds, only Norway, Chile, New Zealand agreed in advance to speak to Reuters on the sidelines; when contacted on the ground China also spoke. Others either declined to comment at all or did not return email.

First, you have the Brazilians who are worried about hot money and have already slapped a tax on foreign investments in domestic bonds and stocks in order to cool down capital inflows.  They want the G20 to take action against what their central bank chief calls "imbalance- and bubble-building".

Next you have the Americans and other big economies who know that the huge amounts of stimulus they have put into the world economy have to be removed eventually. They are not ready to do it yet, but expect the G20 countries to discuss how they are going to "sequence" the great unwinding.

And then there is Argentina, which is not alone in noticing that talk of unwinding tends to put investors on edge.  Its central bank governor wants the big countries to be careful, fearing a rapid reversal of stimulus policies could mean big outflows in emerging market countries such as, er, Argentina.

So a tricky balance, a super-sensitive investor audience, and plenty of domestic politics. Fore!

The discrediting of the efficient markets theory in the aftermath of the financial crisis appears to have been accompanied with growing support for the view that rather than efficient in nature, financial markets are predisposed towards the formation of bubbles.

A bubble can simply be defined as an occurrence that begins when the price of an asset has been driven significantly above it "fair" value. According to the efficient markets theory this would not happen.

If bubbles are a natural outcome of financial market activity it is relevant to ask whether the very loose fiscal and monetary policies of many central banks and governments are presently sowing the seeds of the next bubble.

Even though the real economies of the U.S., UK, Eurozone and Japan continue to be defined by expectations of rising unemployment and falling real wages, access to cheap money has already helped restore the profitability of many investment banks.

In turn, this has fed risk appetite which is evident in the rally in stocks since the spring, increased demand for "risky" currencies and a recovery in commodities prices. Brent oil has rallied by 128 percent from its 2009 low. The ability of oil to rally despite the existence of oil supplies well above the seasonal average suggests there is already speculative element in this market which could be in danger of driving prices above their fair value.

This week’s meetings of the Federal Reserve, the Bank of England and the European Central Bank have focussed attention not so much on rates, but on the extraordinary policy decisions taken by these central banks in the wake of the financial crisis and whether conditions are ripening in favour of a gradual withdrawal of some of these policies.

The Fed last week ended its $300 billion treasury bond purchasing plan, though it will carry on buying mortgage backed securities. The Bank of Japan last week announced that it will stop buying corporate bonds at year end. The Reserve Bank of India also removed emergency support measures last week.

This week there is speculation that the ECB could announce that it will hold no more 12-month cash tenders next year. By contrast the Bank of England is expected to increase quantitative easing at the November 5, Monetary Policy Committee meeting. Supporters of quantitative easing continue to stress that the lack of clear inflation pressures suggests there is room for these plans to be extended.

However, the lack of response in either money supply or inflation indices could equally be illustrating that these plans are not having a significant impact on the real economy and are therefore no longer appropriate. The paring back of these plans are likely to have an impact on the ability of some banks to turn an easy profit and thus should rein in risk appetite and limit speculative and "bubble" forming activity.

Unfortunately, a bubble can only be truly confirmed after it has burst; a characteristic with clear destabilising consequences. If bubbles are natural phenomena within financial markets, the need for tighter regulation and ongoing reviews of processes that oversee the financial system are absolutely necessary.

This conclusion, while in complete contrast to the implications of the efficient markets theory, ties in very well with the political desire to reform the banking regulatory framework in order to protect the tax payer from future hefty bank bail-out costs. The banking landscape, while already vastly different from just two years ago could continue its transformation for years.

When I heard about GM keeping its Opel unit, that line from a song by British band Coldplay came to my mind. After all those long nights of paltering on job cuts and money, GM was having a change of heart.

The sale of Opel to a group led by Canadian car parts maker Magna -- announced in September -- was widely considered a done deal. Turns out, it was less done than more. Citing improving business conditions and the strategic importance of Opel, GM decided it would be better to alienate the German government that provided it with a loan to sweeten the sale of the unit to Magna than to lose the business. GM said it would repay the rest of the 1.5 billion euro ($2.2 billion) bridge loan if Berlin requested. The loan helped save Opel from being sucked into GM's dip into bankruptcy this year.

"This is a black day for Opel," an employee, who declined to be named, said in front of the company's headquarters in Ruesselsheim, near Frankfurt. German government officials were said to be seething, as were the Russians, who's Sperbank had tied up with Magna to do the deal. But not all of Europe was angry. British unions welcomed the news. "It is fantastic news for the UK and right that General Motors does not break up its family and instead retains ownership of (Opel sister brand) Vauxhall," said Tony Woodley, joint general secretary of the Unite union.

Analysts say big questions remain about what GM will do with Opel when consumer-friendly car scrapping schemes expire. At that point, will it be back to square one?

CF is itself fending off a hostile takeover bid from Agrium. Last month, possibly throwing a monkey wrench into CF's bid for Terra, Agrium said it would sell part of a nitrogen fertilizer facility to Terra to overcome regulatory issues related to its hostile takeover bid for CF.

In its latest move, CF is offering $32 in cash -- including a $7.50 special dividend that Terra plans to pay -- and 0.1034 of a share of CF common stock for each Terra share. That would amount to $40.61 per share based on CF's Friday closing price and represents a 28 percent premium to Terra's Friday closing price, the company said in a statement. It is about 5 percent higher than CF's previous stock bid of 0.465 CF shares for every Terra share.

But perhaps more importantly, the new bid would not require approval from CF shareholders as it is now mostly cash. Terra had said CF would not be able to get its all-stock offer approved by CF shareholders. Cutting them out of the process is always a good way to help move a deal along.

As if that was not enough, volatility soared. The VIX fear gauge leapt 37.8 percent in the week, nearly 30 percent alone on Friday. Cross-sectional volatility — volatility between stocks as opposed to just the index — is also rising as can be seen  (black line) in the graph to the right.

But might it all simply be a matter of timing? Credit Suisse estimates that 22 percent of mutual funds end their fiscal year at the end of October. So the big sell off could at least in part be due to managers ensuring their end of year profits look good.

Confidence in the emirate had run aground earlier this year as investors bet on Dubai's state-linked entities not being able refinance debt. So far, this year it has met all its obligations and with the fresh issue booking about $6.5 billion from regional and international investors, Dubai's doomsday scenario appears to be vanishing. 

With much of the United Arab Emirates' oil coming from the largest of the emirates Abu Dhabi, investors have flocked to the capital this year as appetite for good emerging market debt revives. The spread between Abui Dhabi and Dubai widened at its peak to over 500 basis points in February, but Dubai government efforts to restore confidence -- kickstarted by the UAE central bank buying $10 billion of its bonds -- has helped spreads narrow to about 200 basis points.

Dubai still has a long way go. The next test will be property developer Nakheel resolving its $3.5 billion Islamic bond maturing on Dec. 14 and then a raft of debts in 2010.....but as Harold Wilson once said, "A week's long time in politics."  

For a place so reliably bathed in sunlight, the Dubai property explosion seems to have generated enough construction noise to drown out the environmental debate raging elsewhere in the world.

For the first-time visitor, the scale of the global construction superlatives - The Palm, made from reclaimed land jutting out defiantly into the Gulf, the skyscrapers built in a region where there is no shortage of space - is staggering.

The amount of environmentally 'sinfull' concrete poured over the last decade is ncalculable. Billboards lauding the benefits of solar power look like a bit of an after thought.

Climate change was just beginning to take hold as an issue for property developers when the economic downturn struck and put paid to nascent environmental ambitions.  "Green is not cheap," says Markus Giebel, chief executive of Dubai property group Deyaar Development. "Dubai was on the right track, but there's no money now. People are thinking about survival."
