The RiverPark Long/Short Opportunity Fund returned 0.13% in Q4 2025, underperforming the S&P 500's 2.66% return. The fund increased both gross and net exposure during the quarter, ending at 97.63% long and 18.72% short. Top contributors included Alphabet, which benefited from strong advertising and AI monetization in Google Cloud, Eli Lilly, driven by robust GLP-1 franchise growth, and Intuitive Surgical, supported by accelerating procedure volumes and system placements. Key detractors were Netflix, pressured by subscriber growth concerns and Warner Bros. Discovery acquisition uncertainty, CoreWeave, which faced margin compression and slower enterprise AI workload ramps, and Uber, despite strong operational performance, due to margin expansion concerns and robotaxi competition fears. The portfolio maintains significant exposure to AI/Cloud Computing (16.9%), Internet Media (13.3%), and E-commerce (7.5%) themes. The manager remains focused on high-quality businesses with secular growth drivers while shorting companies with flawed business models, positioning for attractive risk-adjusted returns across market cycles.
The fund employs a long/short equity strategy focused on high-quality businesses with strong fundamentals and secular growth drivers on the long side, while shorting companies with deteriorating financials, unsustainable business models, or excessive valuations.
The manager believes the fund's flexible mandate and disciplined stock selection process are well suited to navigate the current environment, with commitment to generating attractive risk-adjusted returns through all market cycles.

VolatilityManager emphasizes volatility as a structural feature of markets, noting that rare events occur far more frequently than expected. April's volatility event validated their convexity approach, with systematic monetization during stress periods. December saw compressed volatility with VIX hitting year lows, creating buying opportunities despite short-term costs. |

| TICKER | COMMENTARY |
|---|---|
| AAPL | AAPL shares rose in 4Q25 following better-than-feared iPhone 17 sell-through trends and stronger Services momentum. The company reported that early adoption of its on-device AI features exceeded internal expectations, particularly in North America and Europe, where attach rates for Pro models remained elevated. Wearables also returned to growth, helped by new health features and improved battery life. |
| AMZN | This quarter, we took profits in our hyperscaler portfolio companies (Amazon and Google) and increased our position in NVIDIA. |
| DIS | We sold our long-term holding in Disney, reflecting our view that consumer discretionary spending could remain under pressure if cost-of-living conditions stay tight, especially at a time when the company is spending significantly on Parks and Resorts. |
| DUOL | I have followed the company closely since the IPO since my wife was an avid user, not wanting to break her streak in learning Italian. I thought growth would drop off a cliff after COVID as happened with many other companies, and yet, quarter after quarter the company continued to execute. In fact, there are only four companies I can find that have grown revenues greater than 30% for at least the last 20 quarters in a row – MercadoLibre, Axon, Hims, and Duolingo. To have that growth endurance, you've got to be doing something right! Well, the stock was down almost 70% after the valuation got far too rich and management made it very clear they were prioritizing learning over monetization for 2026. That is the right call in my opinion, considering what the core competency of the company is. Duolingo shouldn't be thought of as a language learning app, it's an engagement machine that happens to educate. In service of its mission to make education widely available, it built the data-driven muscle of engaging users. To learn anything, the most difficult part is motivation and that is what Duolingo is good at. In fact, almost 40% of monthly users log into the app every day. For context, Snapchat is at 50%! You're telling me that an app that teaches you Spanish almost has the same level of engagement as the app where teens do all of their communication? As the company broadens its education subjects like math, music, chess, and other areas, retention should increase even more. If you get bored of learning a language, you can hop over to play some chess. And AI will allow the company to create better content for their current subjects and accelerate the broadening of the platform. Paired with the engagement muscle, Duolingo very well could become a must-have app for learning all sorts of things. This vision will take time but it's actually the exact vision of the CEO/founder. The main bear cases are AI translation and that no one actually learns anything. On the latter, it's up to the user. Duolingo can't force you to learn anything. But yes, education apps typically have very high churn. The fact that Duolingo is able to increase paid subs at a rapid rate despite the leaky bucket is incredibly impressive. On the former, language learning isn't all about practicality. For a large portion of users, they're trying to learn English and they actually really want to understand the language rather than use AI translating glasses. And secondly, Duolingo includes a structure for habit formation. The company is already embedding AI into its content program with its Max Tier so as the models improve, so should Duolingo's product. It's easy to say that high engagement, alone, isn't a moat and I'd agree but the company's core competency is A/B testing and therefore, the product improves at a much higher rate than competitors as it scales. We paid ~18x FCF, inclusive of stock-based comp. That's not super cheap but for a company with an exceptional founder and growth endurance rivaling our long-time holdings, MercadoLibre and Axon, we decided to finally start a position. |
| FIS | Fidelity National Information Services Inc represents 2.22% of top holdings |
| GOOGL | In the third quarter, Google, Kairos Power, and the Tennessee Valley Authority announced a major collaboration centered on a novel power purchase agreement. Google followed this announcement with another significant step forward. On October 27, Google and NextEra Energy announced plans to restart the Duane Arnold Energy Center. |
| ISRG | ISRG shares appreciated in the fourth quarter after the company delivered strong Q3 results highlighting continued procedure growth and accelerating system placements. Procedure volumes rose in the mid-teens globally, with notable strength in general surgery and urology, while recurring instrument and accessory revenue grew faster than expectations. Management also reported that the early rollout of its next-generation robotic platform was tracking ahead of schedule, with utilization metrics trending positively across beta sites. |
| KMX | Over the past five years, CarMax's shares declined by 62%, while Carvana's shares rose by 73%, leaving CarMax's market capitalization at roughly one-tenth of Carvana's today. |
| LLY | Eli Lilly shares were a top performer in 4Q25 after delivering strong Q3 2025 earnings in October. Revenue rose 54% year-over-year to $17.6 billion, and adjusted EPS of $7.02 beat consensus of $6.02. Growth was driven by its GLP-1 franchises, Mounjaro and Zepbound, where sales more than doubled year-over-year, alongside strength in other therapeutic areas. Management raised full-year guidance for both revenue and earnings, reinforcing investor confidence in the company's growth outlook. |
| META | On January 9, Meta Platforms unveiled a new agreement with Vistra—the largest generator of competitive electricity in the United States—as well as with TerraPower and Oklo. The announcement builds on Meta's agreement last year with Constellation Energy and positions the company to become one of the largest corporate purchasers of nuclear-generated electricity in the United States. |
| MSFT | MSFT was a detractor in 4Q25 following its fiscal first-quarter 2026 earnings report released on October 29. While results were better than expected operationally, investor reaction was driven by guidance and capital expenditure intensity rather than headline performance. Revenue grew 17% year-over-year, exceeding consensus expectations, and Azure revenue increased 39% year-over-year, also ahead of estimates. However, management guided to a sequential deceleration in Azure growth in fiscal Q2, signaling some moderation after a period of exceptional demand. |
| NFLX | NFLX was the portfolio's largest detractor in 4Q25 following investor concerns around near-term subscriber growth and rising content spending. While revenue grew approximately 10% year-over-year, management guided to slower net subscriber additions in North America and Europe after recent price increases, and margins were pressured by elevated investment in live sports and international content. |
| NVDA | Capital spending from Google, Microsoft, Amazon, Meta, OpenAI, and more have led to Nvidia becoming the Rrst 5 trillion market cap company. |
| SHOP | Shopify Inc. is a cloud-based software provider for multi-channel commerce. Shares rose 8.3% in the fourth quarter, finishing 2025 up 51.1% on strong financial results that outperformed Street expectations. The company is demonstrating rapid growth at scale with gross merchandise value (GMV) and revenues each growing over 30% year-on-year. |
| UBER | UBER was a detractor in the fourth quarter following its third-quarter 2025 earnings report, which delivered strong operating performance but was met with a muted market reaction. Gross Bookings and adjusted EBITDA both came in near the high end of management's guidance, driven by accelerating demand across both Mobility and Delivery. However, investor focus shifted to commentary around reduced margin expansion as the company steps up investment in growth initiatives, including autonomous vehicle partnerships, platform innovation, and commerce expansion. |
