Caution: The trading has not been consistently heavy enough to make the figures significantly predictive. Also, I cherry-picked the swing dates, which tends to make swings bigger than had I picked random December and January dates. Furthermore, of course, in December and January, other events and other motivations exist besides tax incentives.

My Conclusions: Nonetheless, indeed, Fancamp tax-selling does exist. At this time of the year, we can take some consolation in that. However, the degree of it is debatable; and the extent of it widely varies.

What I found a little surprising was the fact that the price swings, as a whole, were more pronounced from mid-December to mid-January as compared to the end of December to the end of January. The reason possibly could be the sellers generally don’t wait to the last day of the year to place their orders.
