I love this article that I found via Greg Plavik's blog. Not being a financial risk management expert means that I can't claim whether it's right or wrong, but I found it interesting.
Why I mention it on this blog is that I spent almost the entire time reading it thinking that the writer could have been talking about IT in general and Oracle performance in particular. That quote above is one of dozens I could have plucked out and reminded me of an old blog post.
It's a long article, but read it and see what you think.

For the avoidance of any doubt, all views expressed here are my own and not those of past or current employers, clients, friends, Oracle Corporation, my Mum or, indeed, Flatcat. If you want to sue someone, I suggest you pick on Tigger, but I hope you have a good lawyer. Frankly, I doubt any of the former agree with my views or would want to be associated with them in any way.
