Uncertainty of 1st qtr may encourage some to sell double and triple baggers early and take the tax hit even if holding only 6 to 9 months, no?? I trade IRA so market tax issues are ??? to me.
"tax hit" is relative to the individual trader. I doubt that a group move will effect markets in this regard. AT least to any extent.
It really depends on the investor / trader and their individual situation.
I guess the bigger question in my mind is how many really bought all the way up from Mar 09 lows. Look at the volume. I think (opinion / minimal fact) there are not as many double and triple baggers in the hands of retail as what may be thought?
