The increase in trading sub-dollar securities, or securities priced below $1, has been a popular topic of discussion in the last few years after more retail investors entered the market during the COVID-19 pandemic. During the GameStop phenomenon in January 2021, there was a massive increase in trading sub-dollar securities. The volume appeared to slow down in the months after these events, however, that decline did not last. In fact, trading sub-dollar securities gained popularity again at the end of 2022 and seems to be holding strong into 2023, driving a significant amount of trading activity.

Cboe Retail Priority, a patent pending unique priority allocation model on Cboe EDGX®, has helped more retail investors to access Cboe’s exchange, leading to an increase in trading, including in sub-dollar securities. The Cboe Execution Consulting Team closely monitors certain trends on Cboe’s exchanges and in the equities markets overall, including in sub-dollar securities trading volumes. In this analysis we explore a significant shift in sub-dollar trading activity across all exchanges and, more specifically, retail volume trends in sub-dollar securities on Cboe EDGX.

Volume Growth Since 2019

Sub-dollar average daily volume ((ADV)) has increased 313% since first-quarter 2019, growing from 442 million shares per day to 1.8 billion shares per day in first-quarter 2023. The recent volume growth is attributed to a few securities, such as MULN and XELA, which trade over 213 million and 168 million shares per day, respectively. During the meme stock phenomenon in first-quarter 2021, ADV in sub-dollar securities peaked at over 1.9 billion shares per day, driven by popular meme stock names, such as Sundial (SNDL), Zomedica Corp (ZOM), Naked Brand Group (NAKD) and Castor Maritime Inc. (CTRM).

The figure below illustrates the ADV growth in sub-dollar securities and highlights those that traded an average of 100 million shares per day or more, providing evidence that this growth is concentrated in a select number of securities.

In January 2023, sub-dollar securities comprised the highest percentage of total market volumes since the meme stock phenomenon in January 2021. Since January 2022, the percentage of the total market comprised of sub-dollar securities increased 6.4%, sitting at 11.2% in February 2023. In that same timeframe, the S&P 500® Index’s percentage of market volumes decreased 1.4% to 20.8%. The S&P 500 has remained relatively stable as a percentage of Total Composite Volume (TCV) at about 20%, while sub-dollar securities continue to increase as a percent of total volume.

Where People are Trading Sub-dollar Securities

A significant majority of the increased sub-dollar securities volume comes from off-exchange trading. In first-quarter 2023, the Trade Reporting Facility ((TRF)) represented about 60.2% market share in sub-dollar securities. TRF’s market share in these securities peaked in second-quarter 2021 with a market share of 68.1%, an increase of 11.7% from 2020. Because of Retail Priority on Cboe EDGX , Cboe’s market share in sub-dollar securities remains relatively strong compared to other large exchange groups. Among exchange groups, Cboe ranks first in sub-dollar securities market share at 13.3% in first-quarter 2023.

The number of sub-dollar securities traded has drastically increased since 2019. In first-quarter 2019, there were 532 securities trading at less than $1. In first-quarter 2023, that number has increased 208% to 1,638. However, the number of sub-dollar securities peaked in fourth-quarter 2022 at 2,019 securities.

Sub-dollar Securities as a Percentage of Total Composite Volume

The percentage of daily TCV for the top 25 sub-dollar securities daily since 2019 peaked on January 5, 2021, at 19.2%. The average percentage of TCV for the top 25 sub-dollar securities in 2023 year-to-date is 6.9%, up 3.6% from 2022, 3.5% from 2021, and 5.3% from 2019. January 24, 2023 was the third largest trading day of all-time for sub-dollar securities, representing 18.3% of the market. The two largest trading days for sub-dollar securities both occurred in January 2021. The high volume day in early 2023 is consistent with the growth trend that has been observed so far this year.

Growing Popularity

We also considered the average number of securities in the daily top 10 traded securities classified by Exchange Traded Funds (ETFs) and the security’s price. As illustrated below, since first-quarter 2019, the average number of sub-dollar securities that were in the overall top 10 traded securities increased by two securities, from 1.2 to 3.4 in first-quarter 2023.

Conversely, the average number of securities greater than $1 in the top 10 traded names has decreased since 2019, as well as from its peak during the pandemic. The average number of ETFs in the top 10 decreased meaningfully during the pandemic as investors moved more into single stocks but that trend has receded with changing market conditions in 2022 and 2023.

New retail traders appear to be gravitating toward even smaller trade sizes in sub-dollar securities. The figure below shows the average trade size in sub-dollar securities since 2019. There was a noticeable shift in average trade size during the meme stock phenomenon in 2021. Between fourth-quarter 2020 and first quarter 2021, trades with a size between 2 and 99 shares increased as a percentage of all trades by 5.9%, while 100-share trades and those between 101 and 9,999 shares decreased the most substantially, by a combined total of 6.1%. Comparatively, since first-quarter 2019, single share trades increased 2.4%, to 5% of all trades in sub-dollar securities.

Trading on EDGX

The chart below shows Cboe EDGX’s total retail volume breakdown by security price, highlighting retail investors’ shift to trading sub-dollar securities. Cboe EDGX is a popular destination for retail investors as EDGX’s book comprises of more than 25% retail volume. EDGX is also home to Cboe’s unique Retail Priority trading mechanism, which benefits individual investors by improving queue priority and time to execution. Since first-quarter 2019, sub-dollar securities have increased from 12.5% of EDGX retail volume to 31.1%.

Conversely, we also looked at sub-dollar securities volume for retail and institutional traders on EDGX. Similar to the trend in retail volume by price group, the percentage of retail volume made up by sub-dollar securities increased 12.3% from first-quarter 2019 to 43.1% in first-quarter 2023. However, the percentage of retail volume coming from sub-dollar securities peaked at 47.1% in third-quarter 2021. A meaningful increase highlighting retail volume made up a considerable amount of EDGX’s volume in 2021.

Based on this analysis, trading in sub-dollar securities has certainly increased in recent years and is a trend to keep a close eye on. This shift has a major impact on the composition of the U.S. equities market and increase in market volumes. The empirical evidence provided by Cboe’s Retail Priority and other retail-attested volume on EDGX makes it clear that there is a direct relationship between the increase in sub-dollar securities trading and the growth of retail investors. The increase in retail trading and sub-dollar securities volume presents opportunities for new traders to enter the market and begin trading their views.
