SEC proposes eliminating Order Protection Rule for trading By Investing.com

The SEC proposed repealing the Order Protection Rule and related quoting restrictions, a major regulatory shift that could lower connectivity, market data, routing and compliance costs. TD Cowen expects finalization in early 2027 and says the move should be positive for equity tokenization, though exemptive relief would still be needed. The proposal may also weaken the economics of smaller exchanges by reducing guaranteed fee collection.

Analysis

This is less about an immediate revenue shock and more about a multi-year rewiring of market plumbing. If mandatory best-price routing weakens, the marginal value of exchange-localized liquidity, speed, and fee capture falls, which should compress the economics of fragmented equity venues and shift bargaining power toward wholesalers, ATSs, and brokers with internalized flow. The first-order beneficiaries are the firms with scale in order handling and the largest downside is for smaller venues whose connectivity and market-data rents are protected today by regulatory inertia.

For NDAQ, the key issue is that it is exposed to both sides of the trade: lower regulatory friction can expand some data and technology lines, but a less protected exchange stack threatens the “toll booth” durability of cash equities. The market is likely underpricing the lag between proposal and implementation; that creates an attractive window where the headline is positive for modernization, while the earnings reset for exchange economics remains several quarters away. The bigger second-order winners may be firms with payments-for-order-flow economics and smart-routing scale, because best execution can shift from venue-price optimization to execution-quality optimization, which is easier to monetize if you control the order flow.

The contrarian risk is that this becomes a “buy the rumor, sell the reform” setup if the final rule is watered down or delayed into 2027, or if broker-dealer best-execution liability tightens enough to preserve many of the current routing behaviors. Another risk is political: retail advocates could frame broader price dispersion as a tax on individual investors, slowing adoption. The structural upside is strongest if the SEC’s changes are paired with tokenization exemptions, because then the reform is not just cost-cutting but a gateway to a broader migration of issuance and trading infrastructure off legacy exchanges.

Key Decisions for Investors

• Reduce NDAQ overweight into strength over the next 2-6 weeks; use any 5-8% rally to trim, since the market may be fading venue-rent compression risk only after the proposal headline fades.
• Pair trade: long SCHW / long Citadel-adjacent market structure beneficiaries if accessible, short NDAQ or XNYS basket for 6-12 months; thesis is that internalization and routing operators gain more from weaker exchange protections than the exchanges themselves.
• Buy medium-dated NDAQ puts or put spreads 9-15 months out to express a delayed-reform/capex-margin compression view with defined risk; the catalyst window is the SEC comment period through the 2027 finalization path.
• For event-driven positioning, own a basket of market-structure/fintech winners on dips over the next 1-3 months, but hedge with an exchange short if the final rule language appears to preserve broad best-execution obligations.
