One of my oldest on-line blog friends is MarkM. We participated together in Bill Cara's blog. He's been a great friend to this blog with his insightful, enigmatic commentary. He even has a suite, er woodshed, when cussin', fussin', smokin' and drinkin', the lubrication of a healthy society, is needed for reparations of one sort or the other.
He has a blog, DURABLE WEALTH, PRACTICAL COMMENTARY ON THE CREATION, PRESERVATION AND TRANSFER OF WEALTH, that you can find here: http://durablewealth.blogspot.com/
Martin Pring is also out with an informative paper: Lost Decade: http://www.pringturner.com/newsletters/LostDecade.pdf On page three, he has a comparison of secular bear markets in terms of percentage loss over time.
And here's a video from Pring on reversal in bonds: http://www.youtube.com/user/mjpring#p/a/u/0/7rM0Me-BfR4
