A photograph of a bare grass hillside at the very last of the light on a March evening. A hard, clean shadow line runs diagonally across the whole slope: above it a narrow strip of hilltop is still lit warm gold by the low sun, and below it the entire field has gone cold blue — a dry stone wall, a metal field gate and half a dozen grazing sheep all already in shadow. The sky above is pale and empty. A farmer in a dark coat walks downhill into the shadow with a stick in his hand and a collie at his heel, seen from behind. Alone on the skyline, very small in the frame and standing in the last lit strip, is a man in an off-the-rack grey suit with a tidy lavender wig and a white-painted face, a blank badge on a lanyard, holding a single small brown paper bag at the front of his waist. The shadow line is a few feet below his shoes and moving up the slope toward him. Nobody is looking at him.

The last one before

S&P 500 6,368.85 · −108.31 · −1.67%

The opening print was 6,453.89 and the index never saw it again. That is the whole session in one fact: six and a half hours, thirty-nine ten-minute bars, and not one of them traded above the first tick of the day. It fell thirty points in the first ten minutes, spent the morning failing to get back, stepped down through the afternoon — 6,403, 6,391, 6,386, 6,378, 6,371 — and made its low of 6,356.08 inside the final ten minutes before closing at 6,368.85, off 1.67 percent. The Dow lost 793.47 points. Decliners beat advancers better than three to one. Consumer sentiment for March printed 53.3. And the volume was 18.1 billion shares against a twenty-session average of 20.4 billion, which is the detail that makes this a page: the worst week of the drawdown ended with fewer people in the room than usual. Monday was the bottom. Nobody knew that on Friday afternoon, and the archive's rule holds — this page carries no stamp either.

The photograph Retail at the Shadow Line

The day's protagonist

Amazon AMZN

Move: −3.95% to 199.34 — through two hundred dollars, and closed twenty cents off the low

Amazon opened at 206.455, made its high of the day in the first minutes at 206.60, and closed at 199.34, twenty cents above its low. It went through two hundred dollars in the afternoon and stayed under. Round numbers are not analysis and the archive knows it, but they are where people put their orders, and on 27 March there was nothing underneath this one. What gives the move its weight is the number that came out the same morning: consumer sentiment for March at 53.3, down from 56.6 in February, and a very long way from the 57.3 that had been the cheerful data point of 6 February. That is the household saying it has noticed the price of petrol. Amazon is the most direct large-cap expression of the American household's willingness to spend money it has not thought very hard about, and it fell nearly four percent while consumer discretionary as a sector fell 3.1 and the banks fell 2.5. Energy rose 1.9 percent, for the second day running the only place to be. The consumer was being marked down and the fuel bill was being marked up, on the same afternoon, in the same tape.

The deeper account

A session in which the opening print is the high is a particular kind of day, and this batch contains three of them — 20 March, 26 March in effect, and this one, which is the purest. At half past nine the S&P 500 printed 6,453.89 and that was the best it ever was. There was no morning rally to fade, no midday reversal, no argument. There were two small attempts, around eleven and around noon, that got back to 6,437.79 and failed, and after one o'clock it simply stepped down: 6,403, 6,391, 6,386, 6,378, 6,371, and then 6,356.08 in the last ten minutes. The close, 6,368.85, was 1.7 percent lower than the open and the lowest of the year by eighty-eight points.

The volume is the part that surprises people. The worst week of a nine-week drawdown, the VIX at 31.05, the Dow down nearly eight hundred points — and 18.1 billion shares changed hands against an average of 20.4 billion. Below average. This is normal and it is badly understood: capitulation days are high-volume, but the days that grind out the last of a decline are usually thin, because the people who were going to sell in a hurry have already done it and the people who might buy have stopped watching. Three stocks fell for every one that rose. It was one-sided and quiet at the same time, which is what the end of something generally sounds like.

Monday was the bottom — 6,316.91 at twenty past three on 30 March, 9.48 percent below the record close this batch opened on, and a close of 6,343.72 for a fall of 9.10 from close to close. Not one person trading on Friday afternoon knew that, and the archive is not going to pretend otherwise: the same rule it applied at 676.53 in 2009 and again at the bottom itself applies here, and this page carries no stamp. The photograph is the last strip of sun on a hillside with the shadow of the opposite ridge climbing the slope toward it, a farmer walking down into the cold with his dog. It is the same high ground as 27 January, nine weeks and 609.75 points later, and this time the light is going instead of the fog rising. Everything after this page in the descent is already written.

The artifact

The day book for the twenty-seventh. Six entries tracking a shadow up a hill, a note that the line came earlier than it has all year, and a last line about Monday. The bottom is three days away in the archive and one weekend away on the page; neither this document nor anyone holding it knows that.

The ledger — what actually happened

Measure	Close	Change	Marginalia
S&P 500	6,368.85	−108.31 · −1.67%	opened 6,453.89 — the high of the day and the first print · never traded above it again in six and a half hours · low 6,356.08 in the final ten minutes
Consumer sentiment	53.3		the March reading, from 56.6 in February and 57.3 in early February — the household had done its own arithmetic on four-dollar petrol
Amazon	199.34	−3.95%	through two hundred dollars; low 199.14, closed twenty cents above it. JPMorgan −3.02% to 282.84
Energy	+1.9%		again the only sector up. Consumer discretionary −3.1%, financials −2.5%, communication services −2.3%
Dow Jones Industrial Average	45,166.64	−793.47	down 1.7 percent; the Nasdaq Composite fell 459.72 to 20,948.36, off 2.2 percent. The lowest levels in more than seven months
VIX	31.05	+13.2%	the high of the drawdown, and the only reading above thirty in this batch
Volume	18.1bn		shares, against a twenty-session average of 20.4 billion. Decliners led 3.38 to one on the NYSE and 3.62 to one on the Nasdaq — one-sided, and thin
Monday	6,316.91		the low of the whole drawdown, printed at 3:20 in the afternoon of 30 March — 9.48 percent below January's record close, which finished the day at 6,343.72 for a close-to-close fall of 9.10. That page is already in the archive, and it carries no stamp either
