The Securities and Exchange Commission (SEC) has removed a significant regulatory barrier to retail market participation, sending shares of popular trading platforms higher.
In December, the Financial Industry Regulatory Authority (FINRA) submitted a request to amend various day-trading rules.
Among them was the $25,000 minimum‑equity rule for pattern day traders, a threshold federal regulators established in 2001 following sharp retail losses during the dot‑com bust.
SEC officials approved the proposal, effectively opening the door to greater participation by retail traders.
The decision, regulators added, “will ease regulatory burdens, reduce customer confusion, and lower compliance costs.”
Over the last several years, retail investors have played a greater role in financial markets, fueled by non-commission mobile trading platforms like Robinhood. But the new rule could further democratize the equities arena.
The SEC also outlined other measures that will lead to structural changes in the retail market.
One measure will be allowing brokerage firms to use real-time data or end-of-day calculations to monitor risk and prevent trades that could exacerbate traders’ intraday margin deficits.
Another reform will require traders to maintain sufficient equity based on their exposure.
Accounts that do not resolve intraday margin deficits within five business days will be subject to a 90‑day freeze on starting or increasing short positions or debit balances. Exceptions will apply to minor shortfalls, the lesser of 5 percent of equity or $1,000, as well as to deficits caused by extraordinary events.
“The new intraday margin requirements will permit more investors to participate in the securities markets and pursue their chosen trading strategies while maintaining safeguards for broker-dealers and investors against the current risks of intraday trading exposures,” the notice stated.
The “pattern day trader” classification—a designation that flags clients who complete four or more day trades within five business days—has also been eliminated.
The changes will go into effect 45 days after FINRA publishes its Regulatory Notice. Firms will also be granted an 18-month phase-in period if they require additional time to upgrade their systems.
Following the dot-com meltdown—one of the largest in U.S. market history—regulators viewed the $25,000 buffer as an effective capital cushion, especially for inexperienced day traders.
At the same time, the reform could serve as an effective liquidity boost to broader financial markets, though it might increase short-term volatility.
The news lifted shares of Robinhood Markets and Webull during the April 15 trading session.
Anthony Denier, group president and U.S. CEO at Webull, says his platform is always preparing to adapt to the SEC’s changes.
Around-the-Clock Trading
The SEC’s action is one of several structural changes for financial architecture over the last 12 months, particularly for armchair traders.One of the most notable adjustments infiltrating markets is the rise of around-the-clock trading.
The Nasdaq Composite Index is inching closer to expanding trading hours to 23 per weekday, split into two sessions. There would be a day session from 4 a.m. to 8 p.m. EST and a night session from 9 p.m. to 4 a.m. EST. A technical pause would happen between 8 p.m. and 9 p.m.
“I think that if we think about the evolution of markets and bringing new technologies to market, anything you can do to drive more capital efficiency opens up the ability for more people to participate,” Adena Friedman, Chair and CEO of Nasdaq, said in a Jan. 29 earnings call.
Additionally, it could allow traders to react to macro data, earnings, geopolitical developments, and other market movements in real time—at home or abroad—rather than waiting until the opening bell.
