Its not surprising that few know how to trade a bear market. They are the toughest markets, and tend to break all those nice models and short term indicators that worked so well in the smooth waters of a gradually rising bull market. Its probably psychological, but we are stunned at how few who actually traded it remember what the 2000-2002 bear market was like. In short, even with a roadmap, it can be a tough trail to navigate.
Here is our comparison of the current bear market and recession with the bear market and recession of 2000-2002. We use the SP500 as a relatively broad market index, as the performance varies among them. In 2000-2 the NDX was the leader to the downside as the trigger for the downdraft was the bursting of the tech bubble. This time around its the housing related stocks and the financials leading the way, but with remarkably broader participation. and demonstrated by the Russell 2000.
What these charts don't show is the extreme volatility behind these simple lines, and the intra-week swings high and low. Bear markets are notoriously hard to trade from positions, unless they are unleveraged and rock solid, and strictly in the intermediate direction of the market.
We'll know quite a bit more in the next two weeks. We'll update this comparison then.

Saint Michael the Archangel, defend us in battle; be our protection against the wickedness and snares of the devil. May God rebuke him, we humbly pray: and you, Prince of the heavenly host, by the power of God, thrust into Hell Satan and all of the other evil spirits who prowl about the world seeking the ruin of souls.
