The point is that arbitrary dates are meaningless without context. The price hit an all-time-high at the end of November 2013 and has been falling ever since, so if you pick the following January as the start of the year, of course it's going to look bad. But not everybody cares about January, or any other arbitrary date for that matter; I certainly don't.
We see too many people using November and December as the only and absolute reference point like Bitcoin started trading at 800$-1100$ when the price has only been that high for a few weeks in total.
