NO, not the SPX - but the options:
"he crux of the argument is that VIX derivatives — futures and options — are subject to potential manipulation. The VIX is calculated using options in the S&P 500 one month out, but the whistleblower says there are "important nuances." He says the calculation is not based on traded prices but on mid prices — the middle between the bid and ask. Crucially, he says, it does not require any trading activity for the VIX index to move — just posted bids and offers."
It's true about VIX manipulations thru options and modifying the formula. SPX also can be manipulated thru the overnight futures market. I still think the top was in and the bottom of the wedge will be tested soon or later regardless the manipulations. The bottom will be broken when the tariffs against Chinese imports are implemented.............
