There you go, I've done it...... In truth I've seen a fair few of these charts over the years comparing this period, and that period with the period pre-Black Monday 1987, and they have never ever worked out.... However.................-Nope I'm not going to say it,, lets just see what happens.....
-- Note : There are some differences:
1) 1987 started at the top,,, this comparison starts at the interim top which occurred after the Flash Crash......
2)1987 was amidst a strong bull move. 2010 is occurring in what I believe is a post-'bear market rally' phase.
3) The Wall Street movie indicator does not suggest a crash until late September - See this link.
