StoryOne LLC 13F Shows $142.3M Equity Holdings

StoryOne LLC's Form 13F filed with the SEC on April 22, 2026 discloses $142.3 million of long equity positions as of the reporting cutoff of March 31, 2026, according to the filing and coverage on Investing.com (Investing.com, Apr 22, 2026; SEC Form 13F, Apr 22, 2026). The filing shows a concentrated tilt toward large-cap US technology names, with Apple (AAPL) accounting for approximately 20.0% of the reported fair market value and Microsoft (MSFT) roughly 15.0%, while NVIDIA (NVDA) represented 13.0% of the portfolio. Versus the manager's prior 13F disclosure for year-end 2025, the April filing indicates a 6 percentage-point increase in technology exposure and an overall reported equity book value up roughly 11.2% year-over-year. These shifts are material for a boutique manager and have implications for sector flows and liquidity in the most heavily weighted positions. Below we provide a data-driven assessment, cross-compare to benchmarks, and identify tactical considerations for institutional readers.

Context

The Form 13F is a quarterly snapshot required by the Securities and Exchange Commission that reports certain institutional holders' long positions in US-listed equity securities as of the quarter-end. StoryOne LLC submitted its 13F on April 22, 2026 for holdings as of March 31, 2026; the filing was summarized by Investing.com the same day (Investing.com, Apr 22, 2026). Small- to mid-sized managers frequently file 13Fs that are both backwards-looking and concentrated; practitioners use them to infer positioning, themes, and potential liquidity pressure points. For allocators tracking manager behavior, a $142.3 million 13F is sizable enough to affect intraday trading volumes in stocks where the manager is top-weighted but not large enough to move major benchmark levels by itself.

Historically, StoryOne's filings (when available) have shown a bias to quality growth names and selective ETF overlays; the April 2026 filing continues that pattern but shows a more pronounced overweight towards semiconductor and core software franchises versus the manager's 2025 year-end disclosure. Comparing the current snapshot to the 13F filed on January 15, 2026 (reporting as of Dec 31, 2025), StoryOne increased its aggregate exposure to the Information Technology sector from 42.1% to 48.3% of reported market value. That rebalancing occurred while the S&P 500 (SPX) traded up approximately 3.8% in Q1 2026, suggesting the manager favored incremental risk on in the rally rather than defensive rotation.

Regulatory context matters: 13Fs do not capture short positions, options, or non-US-listed holdings, and they reflect positions as of quarter-end rather than contemporaneous intraday holdings. Institutional readers should therefore treat the filing as a directional input — useful for trend and concentration analysis but not a complete representation of StoryOne's net exposure or hedge overlays.

Data Deep Dive

The headline numbers from the filing are: total reported long-equity value of $142,300,000 as of March 31, 2026; AAPL valued at approximately $28,460,000 (20.0%); MSFT at $21,345,000 (15.0%); NVDA at $18,499,000 (13.0%); and iShares Core S&P 500 ETF (IVV) at $11,384,000 (8.0%). These values are drawn directly from the line-item fair market values reported in the Form 13F (SEC Form 13F, Apr 22, 2026) and the Investing.com summary (Investing.com, Apr 22, 2026). The numbers imply a top-4 weight of ~56.0% of the public equity book concentrated in two megacaps, one hyper-growth semiconductor, and a core S&P ETF.

Year-over-year and quarter-over-quarter deltas are instructive. Compared with the 13F as of Dec 31, 2025, StoryOne increased its AAPL exposure by 2.8 percentage points and its NVDA exposure by 4.1 percentage points, while trimming a cluster of mid-cap financials (aggregate reduction of 3.9 percentage points). The manager's total reported equity book rose by 11.2% relative to the prior quarter's filing — a rise that outpaced the Russell 2000's Q1 return of 2.1% but lagged the Nasdaq-100's Q1 gain of 6.7% (index returns: Nasdaq-100 +6.7% Q1 2026, Russell 2000 +2.1% Q1 2026; sources: index providers, Q1 2026 performance reports).

Liquidity metrics: combined daily average trading volume (ADV) for the four largest holdings exceeded $35 billion in aggregate in Q1 2026, indicating StoryOne could increase or decrease positions in those names with lower market impact cost relative to a small-cap strategy. Nevertheless, a 20% position in AAPL equates to a block that could represent several days of ADV in the most illiquid market windows, creating potential execution risk if the manager needed rapid deleveraging. Investors tracking potential flow effects should monitor 13D/13G filings, 10b5-1 activity, and contemporaneous SEC filings for cross-holdings.

Sector Implications

StoryOne's pronounced tilt to Information Technology — and specifically to semiconductors and software stalwarts — highlights continued manager confidence in secular IT earnings growth through mid-2026. The overweight to NVDA (13% weight) underscores the firm's exposure to AI-driven demand narratives that have dominated capital allocation decisions across active managers in the last 18 months. Relative to benchmark SPX sector weights (Information Technology ~27.0% of S&P 500 as of Mar 31, 2026), StoryOne's 48.3% allocation is a marked active bet and signals asymmetric upside expectations.

This concentration has implications for peers and liquidity in related names. If StoryOne were to rebalance or reduce risk, selling pressure would likely occur first in the largest cap names listed above, potentially widening bid-ask spreads and producing short-term relative underperformance for stocks with the highest overlapping ownership. Conversely, incremental purchases by the manager — especially in names with meaningful retail participation — could amplify upward moves. Institutional desks and market-makers should therefore flag execution windows around quarter-ends when switching costs and cousin-booking flows are likelier.

Comparatively, StoryOne's underweight to financials and energy relative to the S&P 500 reduces its sensitivity to cyclical reflation dynamics and commodity price shocks. That stance may protect the portfolio versus a rotating macro regime that favors cyclical recovery, but it also exposes returns to the performance of a handful of mega-cap growth names, increasing idiosyncratic risk versus a more diversified benchmark-aware strategy.

Risk Assessment

Concentration risk is the most immediate consideration. With the top four holdings accounting for roughly 56% of the reported portfolio value, StoryOne faces elevated single-stock and theme-specific exposure. Tail risk associated with regulatory, earnings, or macro shocks to the technology sector could produce outsized drawdowns relative to the firm's reported AUM. Equity-market stress episodes historically affect high-beta and concentration-heavy managers more severely: during the tech drawdown of late 2021 and parts of 2022, concentrated growth exposures saw declines materially larger than broad-market indices.

Execution and liquidity risk is secondary but meaningful. Even though the largest names are among the most liquid equities, a forced reduction of a 20% stake in AAPL would demand careful execution to avoid market impact; same for an NVDA position given episodic volatility in semiconductors. Additionally, 13Fs do not capture short book hedges. If StoryOne employs options or shorts to hedge those long concentrations, the picture in the filing may overstate net exposure; institutional readers should seek contemporaneous disclosures or fund-level reporting to assess net exposures.

Counterparty and operational risks also deserve attention. For managers who concentrate in a narrow set of names, prime-broker counterparty limits, margining mechanics on derivatives, and tax-loss harvesting windows can magnify the realized performance gap between gross and net returns. Allocators should validate StoryOne's broader operational controls and stress-test scenarios for correlated drawdowns in the technology complex.

Fazen Markets Perspective

From Fazen Markets' vantage, StoryOne's April 2026 13F represents an intentional, high-conviction stance on a narrow growth theme rather than a default closet index. The manager's incremental increase in technology weighting (up ~6 percentage points YoY) implies a structural preference for earnings compounding over cyclical rotation. That said, the concentration into two megacaps and a leading semiconductor creates a classical barbell of idiosyncratic upside coupled with pronounced downside if the growth multiple compresses.

A contrarian angle: while concentration elevates tail risk, it can also produce alpha in late-cycle regimes when a handful of secular winners decouple from broader macro-sentiment. If AI adoption and enterprise capex continue to accelerate through 2026, StoryOne's NVDA and software exposures could generate outsized returns versus the S&P 500 — but only under a narrow set of macro and earnings outcomes. For institutional allocators seeking differentiated exposure to tech secular winners, a satellite allocation or derivative overlay might capture upside while mitigating single-stock execution risk.

Outlook

Near term, StoryOne's 13F will likely have muted direct market impact beyond signaling concentrated demand for the largest holdings. Institutional desks should watch subsequent SEC filings, fund fact sheets, and any SEC Form 4 insider transactions that could corroborate or contradict the firm's direction. If macro conditions pivot towards stagflation or a harsher rate-hike trajectory, StoryOne's growth-weighted book would be vulnerable to multiple compression and may underperform a more diversified benchmark.

Over a 12- to 24-month horizon, the manager's performance will hinge on earnings execution in its largest positions. Consensus estimates for Apple and Microsoft in calendar 2026 imply EPS growth in the high-single digits, while consensus for NVIDIA embeds stronger double-digit earnings expansion tied to AI demand (source: consensus analyst estimates as of Apr 2026). If those earnings trajectories materialize, the portfolio's concentration could amplify alpha; if not, the converse is true. Allocators should therefore link manager conviction to fundamental catalysts and earnings risk rather than 13F snapshots alone.

Operationally, tracking incremental 13F filings provides a useful signal but not real-time positioning. Institutional investors seeking to replicate or counterweight StoryOne's exposures should consider trade execution timelines, average daily volume, and potential slippage — especially for blocks that represent multiple days of ADV in less liquid market conditions.

Bottom Line

StoryOne LLC's April 22, 2026 Form 13F discloses $142.3M of concentrated equity positions dominated by AAPL (20%), MSFT (15%), and NVDA (13%), signaling a high-conviction technology tilt that raises both upside potential and idiosyncratic risk. Allocators should use the 13F as a directional input while combining it with contemporaneous manager disclosures and execution analysis to assess implementation costs and risk mitigation.

FAQ

Q: Does the 13F filing show StoryOne's short positions or derivatives exposure?

A: No. Form 13F reports only long positions in SEC-defined equities and certain equity-linked instruments as of quarter-end. It does not capture short positions, options, futures, or non-US-listed holdings. For net exposure and derivatives usage, investors should review fund reports, Form ADV (if applicable), or direct manager disclosures.

Q: How should institutional traders interpret the liquidity implications of a concentrated 13F like this one?

A: Concentrated 13Fs in large-cap names generally present lower market-impact risk than similar concentration in small-caps due to higher ADV; however, a 20% position in a megacap can still represent multiple days of ADV in certain trading windows. Traders should model expected market impact, use algorithmic execution, and consider staged trading across liquidity pools to minimize slippage. Historical episodes (e.g., tech drawdowns of 2021-22) illustrate that concentrated growth exposures can suffer amplified drawdowns, reinforcing the need for robust execution planning.
