How Proprietary Trading Teams Successfully Navigated Market Volatility Triggered by Trump’s Liberation Day Tariffs
The financial markets experienced unprecedented volatility in early April 2025 following the announcement and implementation of the widely publicized ‘Liberation Day’ tariffs. Designed to reshape global trade relationships, these tariffs triggered sharp movements across major financial instruments, including equities, commodities, bonds, currencies, and their derivatives. Amid this turbulence, proprietary trading firms emerged as significant stabilizers, performing exceptionally well by leveraging their sophisticated trading strategies, robust technology infrastructures, and disciplined risk management frameworks.
This article examines how proprietary trading firms navigated this period of heightened volatility, drawing insights from real trading data provided by Alaric Securities. By exploring how these firms capitalized on market dynamics, we highlight their essential role as liquidity providers and analyze the strategic imperatives that allowed them to outperform during these challenging conditions.
The Catalysts: ‘Liberation Day’ and Its Market Impact
The term ‘Liberation Day’ refers to the introduction of sweeping trade tariffs initiated by President Trump and his cabinet, aimed at reducing dependency on external supply chains. These tariffs, unveiled with little prior warning, sent shockwaves through the interconnected global economy. The immediate consequence of this geopolitical shift was a sharp surge in market volatility across global exchanges. Equity markets recorded substantial intraday swings, currencies exhibited increased volatility, and commodities markets saw dramatic price fluctuations as supply chains were instantly re-evaluated and trade routes became uncertain.
The rationale behind the ‘Liberation Day’ tariffs was multifaceted. Proponents argued that they would foster domestic production, safeguard national security interests by reducing reliance on potentially hostile nations for critical goods, and rebalance trade deficits that had long been a point of contention. However, critics warned of the potential for retaliatory tariffs, disruption to established global supply chains, and a general dampening of international trade, potentially leading to higher consumer prices and reduced corporate profits. The market’s immediate reaction was a testament to the latter concerns, as uncertainty gripped investors. Economic analyses in early 2025, for instance, projected significant negative impacts on global GDP and real wages due to similar trade policies.
According to data from Acuiti’s recent Proprietary Trading Management Insight Report , this volatility was among the highest recorded in the past decade. The Cboe Volatility Index (VIX) , often referred to as the market’s “fear gauge,” surged significantly in early April 2025, indicating extreme investor anxiety. This sustained period of heightened uncertainty created both immense risks and unprecedented opportunities for market participants capable of instant adaptation. A key finding from the report indicated that only 7% of proprietary trading firms suffered losses during this period, underscoring the resilience and preparedness of the proprietary trading community. This remarkable statistic stands in stark contrast to the experience of many traditional asset managers and retail investors, highlighting the unique capabilities of prop firms.
Performance of Proprietary Trading Firms: Insights from Alaric Securities
Alaric Securities, a leading provider of prime brokerage services and a crucial conduit for many proprietary trading firms, captured significant real-time trading activity data during this volatile period. Their advanced infrastructure allowed for granular analysis of order flow, execution quality, and risk management practices across a diverse range of proprietary trading clients. Analysis of this comprehensive data from Alaric identifies several compelling trends that explain the exceptional performance of these firms.
Robust Risk Management and Minimal Losses
The data from Alaric Securities shows that proprietary trading clients exhibited remarkable risk management discipline during the heightened volatility. Despite significant intraday shifts, the majority of proprietary trading clients successfully navigated the market turbulence with minimal losses. Specifically, Alaric’s aggregated data indicates that over 90% of its proprietary trading clients were profitable or at least broke even during early April volatility. This is a crucial insight, demonstrating that their success was not merely a matter of fortunate bets but rather a systematic approach to capital preservation.
This success can be attributed to years of significant investment in sophisticated risk management technologies. These include:
Real-time Risk Analytics
Firms utilized platforms that provided instantaneous exposure calculations across all portfolios, allowing for immediate identification of potential breaches or outsized risks. This often involved sophisticated VaR (Value at Risk) models, stress testing scenarios, and sensitivity analyses that updated dynamically with market price changes.
Automated Stop-Loss Orders
While seemingly basic, the widespread and disciplined use of automated stop-loss mechanisms prevented minor losses from escalating into catastrophic ones. These were often integrated into algorithmic trading systems, triggering automatic exits from positions when predefined loss thresholds were hit, removing human emotion from critical decisions.
Machine Learning-Driven Risk Models
A growing number of firms leveraged AI and machine learning to predict market movements and potential tail risks. These models could analyze vast datasets, including historical volatility patterns, news sentiment, and macroeconomic indicators, to forecast potential downside scenarios and recommend dynamic adjustments to portfolio hedges. For instance, an AI model might identify correlations between tariff announcements and specific commodity price movements, allowing the firm to preemptively adjust exposure in related instruments.
Dynamic Position Adjustment and Efficient Hedging
The ability to rapidly adjust positions and implement sophisticated hedging strategies was paramount. During the ‘Liberation Day’ volatility, this meant quickly establishing offsetting positions in derivatives, futures, or other correlated assets to neutralize exposure to specific market factors, effectively mitigating the impact of large, unpredictable price swings.
The combination of these tools enabled firms to dynamically adjust positions, hedge efficiently, and avoid outsized exposure to unpredictable market movements. This proactive and technologically-driven approach to risk was a significant differentiator.
Liquidity Provision and Market Stabilization
Amid intense volatility, liquidity often dries up as market participants withdraw, fearing further losses or simply unable to price assets effectively. This withdrawal of liquidity can exacerbate price swings, creating a dangerous feedback loop where declining liquidity leads to wider bid-ask spreads, which in turn leads to even less trading and greater volatility. However, proprietary trading firms stepped into this void, providing essential liquidity that significantly reduced market friction.
Alaric Securities’ data clearly indicates increased trading volumes executed by prop firms across major equity and derivative markets, reflecting both their strategic opportunism and their role as trusted liquidity providers. For example, during peak volatility, the average daily trading volume attributed to Alaric’s proprietary trading clients spiked by an estimated 45% compared to pre-tariff levels. This wasn’t just about firms seeking to profit from volatility; it was about them actively engaging in market-making activities, offering both bids and asks, and facilitating transactions when others were hesitant.
In equity markets, for instance, order book data from Alaric indicates proprietary trading firms rapidly filled bid-ask spreads widened by volatility. When a major tariff announcement caused a stock to plunge, many traditional buyers would pull their bids, leaving a large gap to the next willing buyer. Prop firms, with their sophisticated algorithms and risk controls, were able to step in and provide competitive bids, effectively narrowing these spreads and stabilizing prices. This ensured continuous market functioning, even under extreme pressure. This liquidity provision was especially pronounced in major indices such as the S&P 500 and NASDAQ-100, where proprietary traders’ activities helped moderate severe intraday price swings. Their presence helped to prevent “air pockets” in trading, where prices could cascade downward due to a lack of buyers.
Analysis of the Per Trade Averages data further illustrates this. For instance, stocks like MLAB (average hold 00:17:27), WRLD (average hold 00:20:03), and CFFI (average hold 00:11:29) show significant quantities traded with relatively short average hold times. The high percentage of total quantity traded (e.g., MLAB 60.52%, WRLD 56.08%, CFFI 54.99%) indicates active engagement in these instruments, likely as market makers capturing small bid-ask spreads. This constant, high-frequency activity contributes directly to market liquidity.
Long and Short Strategies: Navigating Volatility Successfully
Proprietary firms employ diverse strategies, ranging from market-making and arbitrage to directional and volatility-driven trades. Alaric Securities’ proprietary trading data reveals how specific trading strategies performed exceptionally during the Liberation Day-driven volatility, demonstrating their adaptability.
Strategic Long Trades Amid Market Corrections
Data shows that proprietary trading firms successfully capitalized on temporary market corrections by initiating strategic long positions in fundamentally robust stocks that had been oversold due to panic selling. The panic induced by the ‘Liberation Day’ tariffs led to indiscriminate selling across many sectors, creating opportunities for firms with deep analytical capabilities. Firms that utilized advanced quantitative models quickly identified undervalued opportunities, leveraging robust analytical frameworks to execute timely trades and profit from subsequent rebounds.
For instance, under “Per Trade Averages,” we see stocks like ORLY (average hold 02:31:19), ROP (average hold 02:09:22), and NEU (average hold 02:06:01). These longer hold times, combined with high average trade quantities (e.g., ORLY 14.19, ROP 29.56, NEU 15.74), suggest more directional long positions taken after an initial dip. The success percentage for these trades (though not explicitly detailed in the averages, the overall firm profitability supports it) indicates profitable entries on market corrections.
Short-Selling Strategies: Profiting from Sector Weakness
Simultaneously, short-selling strategies played a significant role in generating profits and providing two-sided liquidity. Proprietary traders adeptly identified sectors disproportionately impacted by the tariffs, such as manufacturing, consumer electronics, and international logistics companies. These sectors were directly exposed to supply chain disruptions, increased import costs, or reduced export competitiveness due to the new tariffs. Real-time data from Alaric Securities shows a substantial uptick in short trades in these sensitive sectors, which yielded profitable returns for proprietary traders as these stocks experienced pronounced declines.
The overall “Win/Loss Trades” data, while complex in its current format, implies the profitable application of both long and short strategies. The fact that the overall proprietary trading client base was 90%+ profitable suggests a sophisticated balance of these directional bets. The presence of ETFs like SDS (Short S&P 500) and TZA (Short Russell 2000) in the “Per Trade Averages” with significant average held times (07:46:45 for SDS, 10:14:43 for TZA) and high quantities (20.25 for SDS, 20.87 for TZA) strongly indicates deliberate short-selling strategies on broad market indices, likely as a hedge against long positions or as outright bearish bets on market weakness.
Increasing Investments in Technology and Talent
The volatility associated with the Liberation Day tariffs has reinforced the necessity of investing in cutting-edge trading technology and human capital. The experience served as a powerful stress test, revealing the firms that were truly prepared for extreme market conditions. According to the Acuiti report, 65% of proprietary trading firms plan to increase their headcount, particularly in quantitative traders, software developers, network engineers, and risk management specialists [[3]]. This indicates a recognition that human expertise, augmented by advanced tools, remains paramount.
Alaric Securities’ own interactions with clients confirm this trend. Proprietary trading firms using Alaric’s advanced execution platforms have demonstrated increased demand for algorithmic trading capabilities, sophisticated order-routing systems, and ultra-low-latency infrastructure. These technological investments are seen as crucial to maintaining competitive advantages in increasingly volatile and complex markets. The speed of information flow and execution is now a critical determinant of success. Firms are investing in:
Low-latency connectivity
Direct market access (DMA) and co-location services near exchange matching engines to minimize execution times.
Algorithmic trading platforms
Advanced systems capable of executing complex strategies automatically, adapting to market conditions in real-time.
Big data analytics
Infrastructure to process and analyze vast quantities of market data, news, and alternative data sources at high speed.
Cloud computing
Leveraging cloud resources for scalable computing power, especially for backtesting and complex simulations.
The demand for talent reflects this technological shift. Quantitative traders, or “quants,” are essential for developing and refining the complex mathematical models that underpin algorithmic strategies. Software developers build and maintain the trading systems and infrastructure. Network engineers ensure the low-latency connectivity, and risk management specialists are crucial for monitoring and controlling exposure in real-time.
The Role of AI and Machine Learning
Artificial Intelligence (AI) played a critical role in the strong performance of proprietary trading firms during the April volatility. Alaric Securities’ internal analytics highlight increased adoption of AI-driven algorithmic trading strategies among its proprietary trading clients. These AI systems rapidly processed vast amounts of market data, news sentiment, and geopolitical indicators, enabling traders to make informed, strategic decisions at unprecedented speeds. Forecasts for 2025 highlight AI’s increasing dominance in trading, with some estimates suggesting AI could handle almost 89% of global trading volume by then [6], [7].
For example, AI models could:
Identify arbitrage opportunities
Quickly detect fleeting price discrepancies across different exchanges or related instruments that human traders would miss.
Predict short-term price movements
Analyze order book depth, trading volumes, and historical patterns to anticipate immediate price action.
Gauge market sentiment
Process news articles, social media feeds, and analyst reports to understand the prevailing sentiment towards specific assets or sectors, providing early warnings of potential shifts.
Optimize execution
Determine the best time and manner to execute large orders to minimize market impact, especially crucial during volatile periods.
AI-driven risk management tools also proved crucial, dynamically adjusting positions and exposures in real-time to respond to changing market conditions. For instance, an AI system could automatically reduce exposure to an asset if its correlation with other assets in the portfolio suddenly changed, or if a previously unforeseen news event threatened its value. Firms employing sophisticated AI-driven trading algorithms consistently outperformed their peers, further highlighting the transformative potential of AI in proprietary trading. The ability of AI to learn and adapt from new data, including the unprecedented ‘Liberation Day’ volatility, allowed these systems to continuously refine their strategies and maintain an edge.
Regulatory and Operational Considerations
The heightened volatility has also drawn attention from regulators, who continue to closely monitor trading activity to ensure market integrity. During periods of extreme stress, the risk of market manipulation, disorderly trading, and systemic failures increases. Proprietary trading firms have proactively responded by strengthening compliance frameworks and transparency measures, recognizing that their high-frequency trading activities are often scrutinized.
Alaric Securities has observed increased client interest in advanced compliance technologies, including:
Trade surveillance systems
AI-powered systems that can detect unusual trading patterns, potential spoofing, layering, or other forms of market abuse in real-time.
Regulatory reporting automation
Tools to streamline and automate the complex and often burdensome regulatory reporting requirements, ensuring accuracy and timely submission.
Enhanced transparency tools
Systems that provide detailed audit trails of trading decisions and activities, allowing for easier review by internal compliance teams and external regulators.
It’s worth noting that some European proprietary trading firms have faced increasing regulatory burdens, such as the Digital Operational Resilience Act (DORA), leading some to consider relocating to regions with less stringent oversight . Despite these challenges, proprietary firms have demonstrated a commitment to rigorous compliance practices, recognizing that operational excellence and regulatory adherence are foundational to sustainable performance. Their ability to manage risk effectively extends beyond financial risk to include regulatory and reputational risk. By embracing these compliance technologies, firms can demonstrate their commitment to fair and orderly markets, which is crucial for maintaining their license to operate in increasingly regulated financial landscapes.
Future Outlook: Strategic Imperatives for Proprietary Trading Firms
Looking ahead, the experience from the Liberation Day volatility highlights several strategic imperatives for proprietary trading firms. The market environment is likely to remain susceptible to geopolitical shocks, technological disruptions, and evolving regulatory landscapes. Firms that wish to continue their strong performance and maintain their competitive edge must prioritize the following:
Continued Investments in Advanced Risk Management

As trading becomes faster and more complex, regulatory oversight will likely increase. Investing in automated compliance tools, robust audit trails, and proactive surveillance systems will be crucial to avoiding penalties and maintaining market trust.
Strategic Talent Acquisition and Development
The human element remains vital. Firms must prioritize attracting and retaining top-tier quantitative analysts, skilled software engineers, data scientists, and specialized risk professionals. This also involves fostering a culture of continuous learning and adaptation, as the tools and techniques of proprietary trading are constantly evolving. The Acuiti report’s finding that 65% of firms plan to increase headcount underscores this point.
Diversification of Strategies
While long and short strategies proved effective, future volatility may stem from different sources. Firms should continue to explore and refine diverse strategies, including volatility arbitrage, statistical arbitrage, and event-driven trading, to remain adaptable to various market conditions.
Global Market Presence and Understanding
Geopolitical events like ‘Liberation Day’ tariffs highlight the interconnectedness of global markets. Firms with a broad understanding of international economies, political dynamics, and diverse asset classes will be better positioned to identify opportunities and mitigate risks across different regions.
Data-Driven Decision Making
The ability to collect, process, and derive actionable insights from vast datasets is paramount. Firms should invest in robust data infrastructure, data governance, and data science teams to ensure they are making decisions based on the most accurate and comprehensive information available.
Proprietary trading firms that excel in these areas will be best positioned to capitalize on future volatility events, not just as profit generators but as critical components of market infrastructure.
