As I said in the last SPX article, the S&P 500 experienced a notable decline of 10% within three months after the previous U.S. credit downgrade:

Now it seems like SPX, the S&P 500 index, started to follow the pattern.
According to the past retracement, this time the Price Target of SPX is $4080 by October.

Looking forward to read your opinion about it.
