JPMorgan's Chief Investment Office was given an edict to try to reduce risk-weighted assets, as part of a firm-wide initiative in the face of regulatory changes, and also to shift the synthetic credit portfolio to bee in keeping with the more...
Ellie K's insight:
The default of Kodak in January 2012 was an unexpected credit event that would certainly have effected JP Morgan's Chief Investment Office's decisions leading up to the "London Whale" in May 2012. Eastman Kodak was part of many credit default swap indices. Kodak's filing for bankruptcy on January 19th led to a variety of idiosyncratic risk exposures in JPM's synthetic credit portfolio. * This is part of Alphaville's excellent "CSI: CIO Series" by Lisa Pollack.

How fast is high-frequency stock trading? In the time it takes to read this sentence, tens of thousands of high-speed, computer-automated transactions can occur. Winning traders edge out rivals by intervals measured in nanoseconds. Fans of the practice say that high-frequency traders add crucial liquidity to the stock market. Critics dispute that claim and highlight, instead, lurking perils for the global financial system. Via Complexity Digest
Ellie K's insight:
Yes! It IS time for some greater introspection about this, before there are even worse problems. Right now, there is very little understanding of risks to most people, including the voting public. European regulators seem to have a more realistic view and be willing to act upon it than in the U.S.A. Delete the scoop?

Most hedge funds claim to produce positive absolute returns. The reality is sobering: most strategies still largely depend on stock market performance and those not incorporating equities haven't kept their promises either.

Gary King, PhD has a nice collection of outlier event-themed research work, covering a wide range of fields of study. I think the website uses Harvard's OpenScholar CMS, which is an additional feature worth noting. * The image that accompanies this was my choice (Prof. King has nothing to do with any errors in judgement I might make). It is a photograph of a recent annular eclipse, as observed in Southern California (Spring 2012) via Flickr. Delete the scoop?

Ill-gotten gains are artificially bounded by zero, as there is no data on losses experienced by cybercriminals. Thus the shape and skew (mean and stdev too!) of frequency distributions are incorrect. Also: "Cybercrime surveys... exhibit a pattern of enormous, unverified outliers dominating the data... 90% of the estimate [was] from the answers of 1 or 2 individuals." The significant harm experienced by users rather than the small gain achieved by hackers is the true measure of the cost of cybercrime. Delete the scoop?

The recent interest in the median as opposed to the mean as a representative of common, characteristic value for an observed quantity has caught my attention recently. The latest post from DataGenetics blog does a cute little illustration of that using stick figures, telephones and Microsoft Excel.
Perhaps it is my operations research background, but I did not find the second part of the post to be surprising or non-intuitive, where the concept is expanded from 1-D to 2-D.
