I like to use these comparison charts as a crude road map - they're never going to match perfectly, but the general angle of the climb and time frame is a reasonable guide. If the pattern holds, our cyclical bull doesn't end until next March.

There are reasons to believe a significant pullback is coming - the worst quarter of the presidential cycle is the third quarter of a mid-term election year. Considering the extreme overbought conditions, it seems like we are set up for a 10-15% pullback before the next major run. Of course, that would be too perfect.
