Because 2015 is the year when we had all time high, but the year was end in red. Also, 2014 ended below average growth calculated from 1970. Exactly one year ago touched all time high, and now we have first period of one year with decline from 2011 to now.
Although some people believe we will see new all time high. we have some similarities to the 2008 pre-crisis period. Years with all time highs, but ended in red. Also, moving averages are almost the same.
