NYSE Island Reversal 'escaped'; YET we remain 'ship- wrecked' & same levels......an omen?

S&P500 Daily Chart @ Close 04/27/2015

Key Daily Reversal the 1st Sign that something (anything?) is amiss with this aged Rally?
All the following scored same Daily Chart Reversals @ New Highs:
NYSE/ OEX100/ NDX100/ S&P600 (Small Caps); with the R2000 below it's Highs but also scoring an Outside Down Day.
Should we care? Perhaps so!
Daily Close below 2075 would go a long way in confirming that 'something' has Corrective potential.
