New grass
S&P 500 2,447.33 · +209.93 · +9.38%
The open was the low. From the first tick it climbed — on a bill that had not yet passed, out of a floor made the day before in silence. By the close the Dow had put up 2,112.98 points, the largest gain ever printed and its best day since March 1933, when the banks reopened; the index rose 9.38 percent, its best day since October 2008. The sea came back the way it had gone out: all day, one direction. Nobody knew yet that the floor would hold. The grass did not ask.
The day's protagonist
The arriving money — no symbol.
Move: +9.38% on a bill that had not yet passed — the Dow's largest point gain ever recorded
Washington had spent the weekend failing to agree, and on Tuesday morning it was merely close — but the market had stopped waiting for votes. Two trillion dollars: direct payments, expanded unemployment, business lending, arriving on top of a central bank that had removed the number from its own promise the previous morning. The index rose nine point three eight percent, its best day since October 2008; the Dow's eleven point three seven — 2,112.98 points, the largest gain ever printed — was its best day since March 15, 1933, when the banks reopened after the holiday, a page this encyclopedia already keeps, eighty-seven years and four wings earlier. The point record was the third raising of the bar in twenty-two days, after March 2 and March 13 had already taken it from the day after Christmas 2018. The floor had been made twenty-four hours before, and nobody knew that either.
The deeper account
Wing 5 closes here, thirty-three calendar days after it opened on an all-time high. Peak, halt, worst-since-1987, floor, best-since-1933: the fastest complete cycle in the encyclopedia.
The Boxing Day page in the previous wing ends by saying its thousand-point record 'stood until March 2020.' It fell three times that March: first on the 2nd — to a rally the locked-out crowd heard through a door, a page also in this wing — again on the 13th, and finally here, where it stands.
Sprout and new grass are the two greens of a Japanese spring; the 1933 page wears the first and this one wears the second. They are the only two days in ninety years to be compared on the same list — the Dow's short list of its greatest days — and they now wear the same season.
The rally was three days early: the CARES Act passed the Senate on the 25th and was signed on the 27th. Markets pay for the announcement and sell the delivery — but not this time.
The recovery from here was neither smooth nor believed. It was, however, the shortest bear market ever measured: a new record high by August 18.
Retail was in the grass at the top of the beach that morning — one step up from the tideline where he had stood the day before, on the first green of the year. The boat that lay stranded on the mud is afloat again in the photograph of this day. He had watched the water go all the way out, and he was there when it came back. The sea filled all day. He stayed to watch it.
The artifact
The ebb filled a card; the flood has one line so far. The reading came in 209.93 over yesterday's low water, on a bill that had not yet passed, and the keeper left the rest of the lines empty — the recovery was not his to promise. The gauge keeps no opinion.
