the thing I dont like about these charts is they are very start and end specific & results can vary greatly for somewhat different intervals. Supposedly you could fix that by using moving averages over say 30 or 60 days but I have almost never seen anybody do it.

Also regarding the comparison itself, IIRC there was a good buffet quote .."In short term markets are voting machine but in long term they behave as weighing machine". definitely applies in this case.
