绿色区: aggressively going after stocks. willing to take considerable risk
灰色区:Opportunitistic, but always ready to take profit, establish hedge, or cut loss
黄色区: High Alert, need to see evidence market can find support in the lower range of this area before committing. Continue to hedge in the high end of this area.
红色区: most likely bear market is here. Do anything everything possible to protect porfolio
这只是现在的考虑,如果有别的重大变化再调整
