Top gainers trade in $887 clips, dollar-volume names in $17,442

The first two parts of this series measured what it takes to reach each list and how long anybody stays. This part asks what the members look like once they are there. Daily bars carry one field that is more revealing than the obvious ones: the number of trades. Divide turnover by it and you get the size of an average trade, which describes who is doing the trading better than volume ever does.

1. The two lists side by side

Each cell is the median across 181 sessions of that session's median inside the group. The third row is the control. It is every stock that cleared a $1 close and $1,000,000 of turnover on that session, which is the population a day trader could plausibly touch.

2. The clip size is the story

A trade on the percentage list moved $887 at the median. A trade on the dollar-volume list moved $17,442, which is 19.7 times larger. Even against the ordinary qualified stock at $3,458 the gainers list trades in clips 3.9 times smaller. The quartile ranges do not overlap. Across 181 sessions the upper quarter of gainer-list days still traded in smaller clips than the lower quarter of ordinary qualified stocks. That is what a retail-dominated tape looks like from the outside. Many small prints rather than few large ones, which is consistent with what we measured at the top of the book in https://traderwe.com/research/liquidity-when-a-stock-drops-the-bid-thins-on-95-of-sessions

3. The gainers list is not where the money is

This is the row most likely to be misread, so it is worth stating plainly. The top 30 by percent had a median turnover of $12.6M. A typical qualified stock had $14.5M. The biggest movers in the country traded $1.9M less than the ordinary stock sitting in the middle of the same universe. They are busier by count, at 12,277 trades against 6,978, which is 1.8 times more prints. But each print is a quarter of the size, so the dollars come out slightly lower. A large percentage move and a large amount of money changing hands are close to unrelated. The dollar-volume list, at $7,620.1M a name, is roughly six hundred times either of them.

4. Price is the other divider

The percentage list sat at $7.37 and the dollar-volume list at $319.41, a factor of 43. The qualified market sat between them at $34.56. This is not a coincidence of the sample. A given dollar move is a larger percentage on a cheaper stock, so the percentage ranking selects downward on price by construction, and the dollar-volume ranking selects upward because a high price makes large turnover easier to reach. The consequence is practical rather than philosophical. Everything we have measured about spreads and depth varies with price, so the two lists hand you two different cost environments before you have made a single decision.

5. What this means

Read the two lists as two markets rather than two rankings of one market. The names on one are not smaller versions of the names on the other. They differ in price by a factor of 43 and in trade size by a factor of 19.7, which is a bigger gap than most people would guess separates one part of the same exchange from another. Do not assume a big mover is liquid. It is active, and active is not the same thing. The median gainer traded fewer dollars than the median qualified stock while printing nearly twice as often. Size your orders against the clip, not the volume. On a tape where the average trade is $887, an order that is a multiple of that is a visible event rather than a participant.

6. What this does not measure

We are describing composition, not consequence. Nothing here says which list is worth trading, and we did not measure returns. Daily bars give one number per field per session, so intraday shape is invisible. The day range in the first table is a bar statistic, not a description of how the range was travelled. Dollars per trade is turnover divided by the exchange's trade count. Odd lots, hidden executions and trade reporting conventions all sit inside that number, so treat it as a comparison between groups measured the same way rather than as a literal average order size.

7. Sample accounting

The sample is 181 sessions between 2025-12-02 and 2026-08-21, using the top 30 of each list on every session. Exchange test symbols are excluded, for the reason given in part one. Every figure is a median of daily medians. Taking the median inside each session first stops a single extraordinary name from carrying a whole group, and taking the median across sessions stops a single extraordinary session from carrying the sample. The qualified universe requires a $1 close and $1,000,000 of turnover. The dollar-volume ranking is taken on the unfiltered universe, since a turnover ranking applies its own filter by construction.
