Japanese Bull Market

I Believe the Japanese bull market began in early November 2010, and with this disaster and the impending nuclear fallout (I pray there not be one) it seem the bull has ended. However, I don't think that will be the case. History has shown that the Japanese people will pull together and come out stronger than ever. The problem in terms of investing is that of timing. So lets look at the chart. Despite the 20% lopped off in 2 days we are still not oversold. I need to see the Slow STO down to last summer levels, RSI almost there? And I have to tell you the 20% down right know looks really tempting to put the toe in the water, say like a 25% position. So finding the exact bottom is really hard so don't sweat missing it, the downside is where the fear should lie not missing a couple of upside points.
