McLean Asset Management 13F Filed on April 22, 2026

McLean Asset Management filed a Form 13F with the U.S. Securities and Exchange Commission on April 22, 2026, a filing that reports the firm's long equity positions as of the quarter end (March 31, 2026). The April 22 submission is 22 days after the reported snapshot date and well within the SEC's 45-day disclosure window (deadline May 15, 2026 for the March quarter). While 13F filings are backward-looking by design, they remain a high-resolution public window into institutions' public equity allocations, position sizing and turnover. Institutional investors, market liquidity desks and sell-side strategists routinely mine these filings for signals about sector tilts, concentration risk and potential buyers or sellers in specific names. This piece places McLean's filing into context, highlights the limitations of 13F data, and considers near-term implications for market liquidity and benchmark-relative positioning.

Context

Form 13F is the primary mechanism through which investment managers with over $100 million in qualifying assets disclose long positions in SEC-reportable equities; it has been the backbone of US institutional disclosure since 1978 (SEC rule 13f). McLean's filing on April 22, 2026 — reported by Investing.com on the same date — follows that established cadence and reflects positions as of March 31, 2026 (Investing.com, Apr 22, 2026). The timing is meaningful: filings within the first half of the 45-day window are treated by market participants as more actionable because the information suffers less calendar drift versus market moves.

13F data are, however, constrained: they capture only long holdings in reporting categories (exchange-listed equities, ADRs, ETFs and convertible preferreds) and exclude derivatives, short positions, cash, municipal bonds and many private holdings. That means a manager may materially change economic exposures through options or OTC instruments without those moves appearing in the 13F. Practitioners therefore combine 13F reads with other public signals — company 10-K/10-Q disclosures, ETFs flows, and broker-dealer block prints — to build a fuller picture.

For sell-side desks and counterparties, the immediate utility of McLean's filing is identifying concentrated names and potential liquidity demand. A manager that shows outsized concentration in a mid-cap name, for example, can create market headaches if that position needs to be monetized quickly. Conversely, increased weight to large-cap, highly liquid names generally signals less immediate liquidity stress.

Finally, the broader market context matters. As of April 22, 2026 the S&P 500 (SPX) had returned X% year-to-date — note: readers should cross-check live market levels — and sector rotation since the March quarter close has been meaningful in certain pockets. A 13F snapshot therefore serves as a retrospective lens on where reallocations had materially occurred by quarter-end rather than a forecast of what managers are doing today.

Data Deep Dive

The singular data points that underpin any 13F read are the filing date (April 22, 2026, Investing.com), the reporting date (March 31, 2026, per SEC 13f rules), and the statutory 45-day filing window (deadline May 15, 2026 for the March quarter). Those three time-stamps define how stale the data are and how quickly counterparties need to adjust. For McLean, a 22-day lag between the reporting date and the filing date is modest when compared to the maximum 45-day lag and makes the listing more actionable for high-frequency liquidity assessments.

Analysts typically extract three pieces of structured information from a 13F: position size (share count and market value), concentration (percent of reported 13F portfolio value), and direction (new, increased, decreased, or eliminated positions relative to prior quarter). When combined quarter-over-quarter, those inputs create a map of turnover and style drift. For example, a manager that increases weighting to cyclical sectors quarter-over-quarter while trimming defensive staples is signaling a tactical risk-on posture; conversely, a move into high-dividend utilities would suggest a more defensive reallocation.

Comparative analysis versus benchmarks is essential. The S&P 500, for instance, has consistently had technology weights in the mid-to-high 20s percent range over recent years; managers whose 13F weightings deviate materially from benchmark weights are either pursuing active alpha strategies or expressing structural conviction. Readers seeking a live comparative dashboard should pair the 13F read with benchmark sector weights and contemporaneous ETF flows — resources available through our institutional coverage and research hub at Fazen Markets.

Lastly, the granularity of position sizes can illuminate trade impact. Large positions in small- to mid-cap stocks imply higher market-impact costs upon liquidation. Conversely, sizable stakes in mega-cap names will generally be easier to unwind without moving prices materially. Market-makers will price these liquidity considerations into bid-ask spreads and block trade commissions.

Sector Implications

Even absent a full roll-up of McLean's position list in this briefing, the structural lessons from any mid-sized asset manager's 13F are consistent: sector tilts reported at quarter-end inform both relative performance expectations and potential sector-level flows. For example, if a manager disproportionately increases weight to financials versus technology, it could be tilting toward a higher beta, value-oriented stance — an important signal for peers and allocators watching style cycles.

From a microstructure standpoint, sector concentration matters for market liquidity. If multiple managers reveal increased exposure to the same small-cap industrial names, the aggregated demand can temporarily tighten liquidity until market makers step in. The opposite — simultaneous reductions by multiple managers — can produce outsized price moves. Trade desks use 13F patterns to provision capital and adjust inventory accordingly ahead of anticipated follow-through flows.

Comparisons versus peers sharpen the insight. A single manager adding exposure to commodity-exposed names is not as consequential as a cluster of managers doing the same. That peer comparison requires aggregation across filings; our institutional clients can access such aggregation tools through our equities research products. Historical patterns show that correlated reallocations among large managers are a leading indicator of short-term volatility in the affected names.

Risk Assessment

Investors and counterparties should interpret 13F changes through the lens of reporting limitations and information latency. The most important operational risk is mistaking a 13F disclosure for a real-time signal. By design, the data are backward-looking; subsequent derivative overlays, pair trades and outright liquidations can materially alter exposures without being captured. That timing mismatch increases the risk of overreacting to a single filing.

Concentration risk is the second operational consideration. High single-name concentration in a 13F — particularly in illiquid stocks — elevates counterparty risk for prime brokers and creates potential forced-sale scenarios under stress. Conversely, a 13F dominated by ETFs or mega-cap names implies lower idiosyncratic liquidity risk.

Market-impact risk should also be quantified. A manager whose 13F shows a 5%+ position in a sub-$5bn market-cap firm will face materially higher impact costs relative to the same share of a $1tn market-cap company. Risk managers calibrate stress tests using position sizes from 13Fs as a starting point, then layer on hypothetical price moves and liquidity haircuts.

Outlook

In the weeks following an early 13F filing like McLean's, the market reaction often depends on whether the filing reveals concentration in names that have already moved. If a large, illiquid name appears as a top holding and its price has risen materially since quarter-end, counterparties will watch for potential rebalancing flows. Conversely, diversified filings concentrated in large-cap, liquid names rarely provoke sharp price responses.

For allocators and systematic desks, 13F data remain one of several inputs for constructing conviction-weighted portfolios. The usable alpha from a single filing has diminished as analytics vendors commoditized 13F parsing, but cluster analysis across managers still yields insights about crowded trades and systemic liquidity risks. Our expectation for the immediate term is continued reliance on 13F reads to detect concentration and potential cross-manager crowding, while treating the specific holdings list as retrospective rather than prescriptive.

Fazen Markets Perspective

Fazen Markets assesses McLean's April 22, 2026 13F filing as a tactical data point rather than a strategic revelation. The filing's value is highest when used to triangulate with higher-frequency signals: block trades, ETF flows, TRACE data and options positioning. A contrarian insight is that early 13F filers can sometimes be the least informative — managers who file early are often simply compliant and not necessarily signaling conviction. Conversely, managers who delay to the later part of the 45-day window may be more intentional if they wait until they have fully reconstituted exposures post-quarter close.

Our differentiated view is that the market should treat McLean's filing as part of a mosaic. Machine-driven scraping of 13Fs has created an arms race; the next layer of edge comes from combining filings with execution footprints and short interest trends. That synthesis can reveal whether a reported long position is paired with a latent short exposure via derivatives — a nuance not visible in the raw 13F.

Bottom Line

McLean Asset Management's Form 13F filed April 22, 2026 provides a timely but backward-looking window into the firm's public equity holdings as of March 31, 2026; practitioners should use it as one input among many to assess concentration and liquidity risks. Treat the filing as a diagnostic tool, not an immediate market blueprint.
