http://en.wikipedia.org/wiki/Empirical_evidenceSo, were those who expected the bounce this morning -- absent Overstock news -- wrong?
What is your evidence that the news
caused the rally? You are suggesting that absent this news, the market would not have rallied. What is your evidence for that?
Empirical evidence includes observation (ie past news of China creating crash)
I didn't say anyone who was expecting a bounce was wrong.
I did not suggest that absent this news the market would not have rallied.

Observation is only the first step. You must empirically demonstrate causation. This, in this case, is impossible.
My feeling was that since you assert that the news
caused the rally, that the rally would never have come to fruition without it. Hence, those expecting the rally absent news would have been wrong.
