Mish's Global Economic Trend Analysis:
"The important point in above chart is that the move up from the March low is likely a correction, not the start of a new bull market. That information alone is worth far more than any details as to how the market may decline from here. Many patterns are still in play.
Depending on the index, you can count these moves off the bottom as a simple A-B-C correction as shown, or as an A-B-C-D-E wedge. We'll know which one was correct in hindsight, but both suggest stocks will eventually make new lows - either sooner (in 2010) or later. A multi-year top could be in. Fundamentally, it should be in."
