Update on commodity index reweightings

A bit of an update to yesterday's news on reweightings in the Goldman Sachs Commodity Index (GSCI).

While we were searching to find the large changes in energy weigtings reported by the NY Post (see update in yesterday's GSCI post), we came across some notable shifts in the makeup of the Dow Jones-AIG Commodity Index.

The print edition of today's Financial Times reported notable changes in the Dow Jones-AIG's weightings for base metals and natural gas.

Base metal prices extended their slide, with nickel and zinc prices falling after an announcement by Dow Jones that it is adjusting the weightings of the 19 futures contracts in its Dow Jones-AIG Commodity Index. It said nickel would be cut to 2.7 per cent from 5.7 per cent and zinc would be cut to 2.8 per cent from 4.9 per cent.

Dow Jones said it would boost the weighting of US natural gas to 13 per cent from 7.3 per cent. The company rebalances its benchmark commodity index at the start of each year. Historically it reduces the weighting of the best performing commodities from the previous year, and increases the weighting of underperforming commodities.

Hope we're up to date on these issues. Sorry for the delay in posting, we had some difficulties in accessing & editing the blog earlier today.

And for more on the recent commodities action and base metals correction, please see Rob Kirby's FSO Monday market wrap up, as well as George Kleinman's latest article, "Collapse or Correction?". Good reading!

Slate profiles Victor Niederhoffer

Slate's recent profile of writer/speculator, Vic Niederhoffer has been getting some attention from traders and finance types in recent days. I thought we'd take a look at it here too, to offer up some possible educational value from Vic's experiences with trading and loss. Here's an excerpt from Slate's profile of Victor Niederhoffer : " I've enjoyed getting your e-mails. It sounds like you've thought a lot about being wrong. Well, the reason you contacted me, to call a spade a spade, is that I'm sort of infamous for having made a big, notorious, terrible error not once but twice in my market career. Let's talk about those errors. The first was your investment in the Thai baht, which pretty much wiped you out when the Thai stock market crashed in 1997. I made so many errors there it's pathetic. I made one of my favorite errors: "The mouse with one hole is quickly cornered." That is key. There are certain decisions you make in li

Clean Money - John Rubino: Book review

Clean Money by John Rubino 274 pages. Hoboken, New Jersey John Wiley & Sons. 2009. 1st Edition. The bouyant stock market environment of the past several years is gone, and the financial wreckage of 2008 is still sharp in our minds as a new year starts to unfold. Given the recent across-the-board-declines in global stock markets (and most asset classes) that have left many investors shell-shocked, you might wonder if there is any good reason to consider the merits of a hot new investment theme, such as clean energy. However, we shouldn't be too hasty to write off all future stock investments. After all, the market declines of 2008 may continue into 2009, but they may also leave interesting investment opportunities in their wake. Which brings us to the subject of this review. John Rubino, author and editor of GreenStockInvesting.com , recently released a new book on renewable energy and clean-tech investing entitled, Clean Money: Picking Winners in the Green Tech Boom .
