Quote from Aardvark:
It is interesting how often markets do go higher during "holiday" periods of low volume (pro players on holiday).
[Random speculation alert] Agree, high probability that any significant move today can be ignored or be an opportunity to scale into positions that fade the move. [/Random speculation alert]
. Do not go lightly into naked options based on that kind of comparison. As the market moves against you, the real differences are painfully obvious.
