TED Talk: How Algorithms Shape Our World

Here's a terrific TED talk by Kevin Slavin focusing on automated trading. I've been writing and speaking about how XBRL will interact with the world of automated trading and how that pushes, or should push, data quality to the top of the priority list for companies reporting to the SEC for a while now. But the SEC is still complaining about things like issuers not getting the plus and minus signs right in the data. It's a combustible mix.

XBRL Wiki-onomy Explodes The number of unique extension tags, tags companies create when they can't find a good fit in the current US GAAP dictionary, had been running around 8,000 . There are roughly 15,000 in the standard US GAAP set. This quarter the number exploded to about 48,500. The main cause of the increase is probably the set of companies that had to move into "detailed" tagging. That means placing every number in the Notes section of their 10-Q into this format. This number is way north of any expectations I had heard.
