I don't know, do care (options vesting soon, so "up" right now is tactically important).
More generally I think the question on the turn isn't up or down but the volatility of the down and the follow-on psychological effects on investors. We've so quickly moved into new territory that I think it's hard for people to calibrate on the percentages rather than the numbers.
100 Dow points when the Dow was at 10k was a 1% move. Stack a few in a row and something has really happened. 100 Dow points at 25k shouldn't even register as Much more than an aberration, yet the financial news still reports 100 points breathlessly.
On the flip side, when we do take a 10% correction, how will the typical investor reaction to CNBC wailing about a drop of 2500 points on the Dow? Or, even we catch a modest bear, 5000 points? CNBC will no doubt roll out entirely new graphics with skewed graphs where the y-axis crosses at 17500 showing the tremendous, unheard of, first-in-history 5000 point drop.
I have no idea when this will happen but if it happens soon (before people have had a chance to mentally recalibrate), I think this is quite likely to induce more volatility to the down side.
