A photograph of a small traveling fair on a cold October evening at dusk, the sky deep grey going dark. The frame is dominated by an old pirate-ship swing ride, its hull painted a once-bright crimson now faded and chalky with weather, caught in the instant just past the bottom of its arc and beginning to rise again — riders pressed back into their seats, a girl's hair streaming, the ship's trailing edge faintly blurred while the rest of the frame is sharp. Below it a thin evening crowd watches; the ride operator leans on the control rail mid-yawn; puddles on the trampled ground catch the ride's lights. At the near edge, a respectful distance back, seen from behind, stands a man in full clown makeup and a grey suit a half size too big — tidy lavender side-parted hair — perfectly still, head tilted slightly up, watching the ship climb away from its lowest point, his hands clasped behind his back holding a small brown paper bag. Nobody ordered the turn. The arc did it.

The turn nobody ordered

S&P 500 3,669.91 · +92.88 · +2.60%

The same hot number, the same fall — and then, from nothing, five and a half percent up off the lowest price the bear market would ever print.

The day's protagonist

The same number, again — no symbol.

Move: 3,491.58 at 9:40 — the lowest price of the bear market, and the last time anyone saw it

September's inflation report was hot for the second month running: 8.2% against 8.1% expected, with core inflation at 6.6%, a forty-year high. The market did exactly what it had done a month earlier — fell hard, straight through the year's low, to 3,491.58. And then, with no new information of any kind, it turned. Five and a half percent off the low, the fifth-largest intraday reversal in the index's history, closing up 2.60% on a day whose news was unambiguously bad. No explanation has ever satisfied anyone: positioning, options expiry, exhausted sellers, all plausible, none provable. What is certain is the level. 3,491.58 was never traded again. The bear market of 2022 ended, in price, on the morning of its worst headline.

The deeper account

The bear's closing low came the day before, at 3,577.03. This page holds the intraday floor — which is why the almanac notes 3,491.58 unsealed: records of place go unstamped; the house reserves its record mark for closes.

The wing's CPI pair completes here. Same release, same hot surprise, same direction of shock — and opposite days, one month apart. The palettes are one dye, fresh and faded.

The three bottoms already in this encyclopedia — 2002, 2009, 2020 — were all quiet, and all closes. This one was neither, which is why it is the strangest of the four.

Nothing about the reversal has ever been explained to general satisfaction. The modern market's largest moves increasingly have no author, only mechanics.

From this morning's low the index rose more than sixty percent over the following two years, without ever revisiting it.

The artifact

The morning log — closed by the operator, unbothered

The operator's inspection found nothing because there was nothing to find: cables sound, wind ordinary, and the news — 8.2 against 8.1, core at a forty-year high — unambiguously bad. The ride touched 3,491.58 at 9:40, held it for minutes, and climbed. No explanation has ever satisfied anyone, and none was needed for the level to hold: the floor of the arc was never seen again.
