Can we draw the following hypothesis from the context? 

Context:

The Dow Jones Industrial Average closed at its lowest level in over six years on Thursday, having lost 1.16%, or 89.68 points, bringing it to a level of 7,465.95. It had, at one point, set an intraday bear market low of 7,447.55. It was the lowest ending for the index since October 9, 2002. The Dow has fallen almost fifteen percent since the start of this year.

Hypothesis: The DJIA has fallen twenty percent since the start of the year.
