July 2020 Stock Gainers on News, Micro Caps Included
Ranked by the close-to-close change of the trading session each announcement landed in. How this is measured.
Data as of the trading session of
,
21
of 22 completed market sessions produced ranked moves.
That date is the last ranked session, not the last priced one, so follow-through dates run later.
On 100 of these rows the measured session was reconstructed from the announcement time, because it predates our stored session records.
Every percentage on a row, the follow-through readings included, is measured against that row's own pre-news close, which the row names. A day +5 reading is therefore the move from before the announcement, not a further change on top of the headline percentage.
Rows are ordered by the move measured when the board was ranked. A percentage recomputed from the session's own closing prices can sit a little above or below its neighbours; the rank is the one the measured move gave the row.

NYSE and Nasdaq companies with a market capitalization of $5M or more, measured today, including the $5M to $25M band. The exchange is the one recorded on each announcement, and a release naming several tickers records one venue for all of them. A session that changed hands for less than $25,000 in total is not ranked, because a percentage set by a handful of shares is a print rather than a move. On a board older than a year a fund is identified by its name alone, because an instrument class describes whoever holds the ticker today.6 events never entered this month's eligible pool, because the ticker is a warrant, a unit, a right or a preferred rather than common stock, or carries a stored capitalization above $10 trillion, which is larger than any company has reached.Exclude the $5M to $25M band
3 candidate events for this board could not be anchored to a trading session and are not listed.
1 event was left out of this board because the price series changes basis between the baseline close and the measured one, so the two prices do not describe the same shares of the same company and their ratio measures a corporate action, or a change in what the ticker identifies, rather than a move.
1 event was left out of this board because the ticker had not traded for more than 10 days before the measured session, so no comparable prior close exists.
Company names are not shown on months older than a year, because only the current holder of each ticker is known.
Whole board, unfiltered
In July 2020, the median gainer had given back 18.8% of its move five sessions later; the largest catalyst group was Earnings, 32 of the 100 events, at a median of +21.4%.

Month end falls before day +5 for 37 of these 95 events, so this row is not a later horizon than the one above it. 95 of the 100 events have a month-end close later than the measured session; 5 have it on the measured session itself.
Both figures in a row are measured over the events that have a close at that horizon, the count printed beside each of them, not over all 100 events on this board, which is why the denominators differ between rows.
Repeat runners
Some companies move on news more than once. The left list holds the ones that moved twice or more this month; the right list holds the ones that also moved in the months before it. The ranking above shows one row per move, so a name that keeps coming back is only visible here.
Moved twice or more inside July 2020
Two or more ranked moves this month, each on a different trading day.
Price bands are not shown on months older than a year, because the stored prices are adjusted for splits done since and a company that has reverse-split lands in a band its shares never traded in.

Against June 2020
100 events in the comparable window.
June 2020 median +21.7%, selected from the 2,889 events in that month's eligible pool
July 2020 median +25.1%, 3.4 points above June 2020. July 2020's median is taken over the 100 ranked rows, selected from the 4,759 events in that month's eligible pool.
The two windows drew on pools of very different size, so part of the gap between the medians is how deep into each pool the top hundred reaches rather than how severe the moves were.
How this ranking is measured
Close-to-close change on the measured trading session, against the previous close.
An announcement before 16:00 ET is measured on that trading day; one at or after 16:00 ET, or on a weekend, is measured on the next trading day.
One row per company and measured session. Other announcements the company made in the same session are listed inside the row.
A ranking is a coincidence of news and price on the same session, not proof that the news caused the move. Part of an intraday move can precede the announcement.
No Stated Cause marks a release in which the company itself says it knows of no reason for the move, while Other Announcement marks a release these rules could not classify.
Eligibility uses each company's capitalization today, not its capitalization at the time. Archive boards can therefore change as companies grow or shrink.
Prices are adjusted for stock splits the company has done since, so an older row's dollar figures are stated on today's share count and are not the prices that traded that day. The percentage move, the dollar volume and the relative volume are unaffected, because both prices carry the same adjustment. The session's share count carries the adjustment too, so the shares figure beside the dollar volume is that count restated on today's basis rather than the number of shares that changed hands. Where the ticker was retired the price series stops with it and no later adjustment reached it, so those rows are marked as traded and their dollars are the ones that changed hands on the day.
Market cap is not shown on months older than a year, because only today's figure exists.
NYSE and Nasdaq companies with a market capitalization of $5M or more, measured today, including the $5M to $25M band. The exchange is the one recorded on each announcement, and a release naming several tickers records one venue for all of them. A session that changed hands for less than $25,000 in total is not ranked, because a percentage set by a handful of shares is a print rather than a move. On a board older than a year a fund is identified by its name alone, because an instrument class describes whoever holds the ticker today.
On 100 of these rows the measured session was reconstructed from the announcement time, because it predates our stored session records.
