In March 2009 the S&P 500 (SPX) made a major bottom at 666. Perhaps there could be a major peak at 6,666?
The 08/16/25 blog “Comparison of the S&P 500 in 1987 vs. 2025” illustrated that there could be a Fibonacci price relationship between the late stage of the SPX 1987 bull market with what’s happening in 2025.
The Trading View daily SPX chart that was illustrated in the 08/16/25 blog is shown below.
In addition to this potential price relationship there’s also a Fibonacci time cycle pointing to a potential turn in the last week of August 2025 or the first week of September 2025. This is the bull’s eye zone; there’s always leeway around Fibonacci time/price targets.
Planned news events can cause leeway around Fibonacci time/price targets. Its possible the U.S. FOMC rate announcement on 09/17/25 could be causing the time target leeway.
The 08/16/25 blog noted a broad wide leeway zone of 100 – SPX points around the bull’s eye price target of SPX – 6,600, which was reached on 09/12/25.
It’s rare for the main U.S. stock indices to make significant turns on round numbers.
An SPX rally to or near 6,666 on 09/17/25 could be an important peak.
