Multi year rallies that lead to new highs after breaking out of a multi year sideways consolidation, the
Shiller PE Ratio by Year was at 10 at the time of breaking highs. The 2009 lows did not reach 10 at its lows. The current period broke out of its muli year consolidation with a Shiller PE Ration by Year at 25. Looking left of the chart, 25 has been a level where price has entered into toping area. However, the 1990s rally stayed above 25 for quite some time, so I would only look at this as an observation atm. If the Shiller PE Ratio by Year made a hook down with price at or near all time highs, I would become concerned.
