It was quite a day for retirement planners everywhere as the decisions to show up to work or not tomorrow have been on-again, off-again no less than 22 times today as the all-important Dow 13,000 maginot line was criss-crossed frequently only to end on a disappointingly negative note - washing away all those glorious gains in the last 30 seconds.
Of course, in reality, Dow 13000 was crossed considerably more times (thanks to the fractal nature of the quotes) but being conservative 22 times seemed enough.
