S&P 500, the uptrend holds but the engine loses steam in week eight

The S&P 500 weekly bullish signal is in its 8th week and holds: price above the Ichimoku cloud, four structural moving averages aligned, no close below the 200-week average. But the engine is losing steam. Weekly price action has cooled, the Signal Strength drops to 7 out of 100 and is fading, and the index is hugging its historical highs, just over 3% from the peak. A mature picture, not a reversal.
