Tema ETFs 13F Filed on Apr 15 Signals Position Shifts

Tema ETFs filed a Form 13F on April 15, 2026, disclosing its U.S.-registered equity holdings as of the quarter end on March 31, 2026 (Investing.com; SEC EDGAR). The filing is material for market participants who track institutional positioning by quarter and is filed within the statutory 45-day window required by the SEC (45 days after quarter-end; SEC Rule 13f-1). While 13F data are backward-looking and omit derivatives and short positions, the document remains a primary input for quant desks, active managers, and ETF strategists seeking to triangulate portfolio tilts and potential rebalancing ahead of Q2. This report reviews the filing's timing and regulatory context, quantifies what 13F disclosures can and cannot reveal, and outlines the implications for sector leadership and liquidity sourcing.

Context

The Form 13F filing requirement applies to institutional investment managers managing over $100 million in Section 13(f) securities as measured at quarter-end (SEC statutory threshold: $100,000,000). Tema ETFs' filing on April 15, 2026 therefore confirms the manager met the threshold and is participating in the public disclosure ecosystem that shapes transparency across U.S. equities. The filing date—Apr 15, 2026—is within the mandated 45-day post-quarter deadline (March 31 + 45 days = May 15), demonstrating timely compliance; the filing was reported by Investing.com on the same date (Investing.com, Apr 15, 2026). For market participants, the most relevant timestamp in the 13F is the report date: holdings are as of March 31, 2026, not real-time.

13F filings are constrained in scope: they require disclosure of long positions in specified U.S.-listed equities, ADRs and certain convertible securities but exclude cash, direct short positions, most derivatives, and intraday turnover. That limitation creates both a floor and a blind spot—readers can observe disclosed long exposure but must infer cash, options usage, and short hedges from other sources (SEC 13F rules; industry commentary). For ETF issuers and managers, 13Fs are a snapshot that often understates economic exposures if the manager uses futures or swaps to gain market exposure. Those mechanics became especially relevant in recent years as synthetic exposures and derivatives usage rose in certain ETF niches.

Finally, 13F filings have become a de facto data source for algorithmic strategies and media coverage. The SEC’s transparency regime has not materially changed the 45-day cadence or the $100m threshold in recent years; therefore quarter-to-quarter comparisons are methodologically consistent when evaluating changes in disclosed long positions. The practical effect is that market actors treat 13F deltas—material buys or sells between filings—as signals to validate or challenge intraday price moves rather than definitive trade mandates.

Data Deep Dive

The filing date (Apr 15, 2026) and the reporting date (Mar 31, 2026) are explicit, verifiable data points that anchor any analysis; these are cited in the filing available on SEC EDGAR and were summarized in a brief on Investing.com (Investing.com, Apr 15, 2026). Two regulatory numbers are central to interpreting 13Fs: the $100 million manager threshold and the 45-day filing window (SEC). These thresholds determine which managers appear in the 13F universe and how stale the data may be upon publication.

When parsing a 13F, practitioners extract measurable deltas: changes in share counts, changes in reported market value, and new versus exited positions. Although Tema ETFs' granular position-level numbers are in the filing itself (see SEC EDGAR for the full roster), analysts should convert reported market values into percentage-of-portfolio metrics where possible to compare across managers. A useful comparison is to benchmark a disclosed sector weight against a relevant index weight: for example, convert Tema’s disclosed semiconductor allocation into a percentage and compare it to the S&P 500’s semiconductor weight to reveal relative overweight or underweight positions.

A second concrete datapoint relates to timing: 13F snapshots are quarterly, whereas many ETF products provide daily NAV disclosure and mutual funds provide monthly reporting under Form N-PORT. This frequency contrast—quarterly vs monthly or daily—matters for comparing Tema ETFs to peers. If an ETF sponsor’s daily NAV shows large inflows in April, but the 13F shows a materially different exposition as of March 31, the divergence is a red flag that derivatives or cash management activity is driving the post-quarter footprint.

Sector Implications

Even in the absence of full visibility into derivatives and short exposure, 13F deltas can foreshadow sector rotation if the changes are concentrated. For example, if Tema ETFs shows increased reported value in technology-related tickers between the Jan 1 and Mar 31 disclosures, that can validate a tactical bet into growth versus value for Q2. Sector-level moves implied by a 13F are compared against benchmarks—S&P 500 sector weights or MSCI sector weights—to quantify the scale of the tilt.

Liquidity is another direct implication. Large disclosed purchases of mid-cap or small-cap names in a 13F can signal future flow sensitivity: these securities will experience greater price impact for subsequent ETF rebalancings or secondary market replication. Institutional desks will price this in by widening execution slippage assumptions or pre-funding liquidity using cash equivalents, depending on the fund structure. ETFs that use physical replication must balance trade execution against creation/redemption timing; a 13F that shows concentrated small-cap buys can therefore signal higher operational costs in future periods.

Finally, peer comparison is essential. Tema ETFs’ positioning should be compared with larger ETF issuers and sector-specific peers to judge whether the reported moves are idiosyncratic or part of a broader trend. If multiple managers show the same directional shift in their respective 13Fs, the trade carries more conviction as a structural rotation rather than a single-manager tactical move. Institutional desks will overlay 13F data with fund flow and options open-interest data to build a multi-dimensional picture of conviction.

Risk Assessment

Relying solely on 13F disclosures carries clear risks. The primary risk is backward-looking bias: the March 31 snapshot may be materially different from current exposures. Market participants often treat 13F changes as signals rather than blueprints; that difference in treatment reduces the direct causal market impact of a single filing. Another risk is misreading partial visibility—13Fs omit shorts and most derivatives, creating a false sense of directional exposure. A manager can appear long-heavy in a 13F while being net-market-neutral through swaps or futures.

Operational risk matters as well. ETF replication mechanics—physical vs synthetic—introduce different execution and counterparty risk profiles that 13F filings do not disclose. A physical ETF that discloses concentrated holdings in illiquid names will face greater tracking error risk than a synthetic ETF that can replicate via swaps. Counterparty risk for synthetic replication and the credit profile of swap providers are blind spots in 13F data and should be stress-tested by counterparties and institutional allocators.

A final category is signalling risk. Media amplification of 13F files sometimes creates short-term volatility as trend-following funds and quant models trade the deltas. The risk is amplified where filings coincide with low liquidity periods or where the disclosed positions represent a meaningful share of average daily volume for a given security. Market participants should quantify average daily volume and compare it against any large disclosed position to estimate potential market impact cost.

Outlook

Given the filing cadence, the practical market impact of Tema ETFs’ April 15 13F will be as a validation tool for investors already tracking intraday flows and fund-level disclosures. Over the coming weeks, analysts should triangulate the 13F against ETF-level daily NAV data, fund flow registries, and options open interest to determine whether the March 31 snapshot presaged continued positioning into Q2. If the disclosed moves align with observed net inflows, the 13F functions as corroborating evidence for a trend; if not, it points to derivative overlay or rapid rebalancing post-quarter.

For market-makers and primary dealers, the filing offers input to calibrate inventory and hedging. Dealers will adjust capture rates and hedge ratios based on the expected future creation/redemption activity implied by the filing. For large, concentrated disclosed positions in lower-liquidity names, expect dealers to require wider spreads and more active hedging to mitigate execution risk.

Institutional allocators should also use the filing as a diagnostic, not a directive. A 13F that shows rotation into a sector may be one piece of the puzzle; the complete view requires overlaying macro indicators, earnings trajectories, and valuation metrics. That disciplined approach separates signal from noise in the 13F cycle.

Fazen Markets Perspective

Our contrarian read on 13F dynamics is that the market increasingly overweights the informational content of quarter-end snapshots and underweights off-balance-sheet exposures. While headline 13F deltas generate media traction, the marginal value to sophisticated investors has decreased as derivatives and synthetic exposures have grown across the ETF industry. We therefore caution against treating a single manager’s 13F as an actionable playbook; instead, use it to generate hypotheses to be tested against higher-frequency datasets such as intraday flows, options skew, and primary market creation/redeption activity.

Practically, that means combining 13F signals with other proprietary indicators: compare the filing to daily NAV and flow data on the ETF sponsor’s website, cross-check open interest in liquid options to infer convexity bets, and monitor SEC Form N-PORT (for registered funds with monthly reporting) where available. For readers looking for data feeds, Fazen Markets provides curated datasets that merge 13F snapshots with fund flows and options activity to produce forward-looking stress scenarios (topic). This integrated approach reduces false positives from 13F rhythm and highlights genuine structural rotations.

We also observe a behavioral effect: smaller managers’ 13Fs often punch above their weight in headlines, but their market impact is limited unless corroborated by similar moves among the largest custodial managers. Therefore, the most actionable information is not an isolated 13F but cluster analysis across filings, which Fazen Markets has been developing as a quantitative product offering (topic).

Bottom Line

Tema ETFs’ Form 13F filed Apr 15, 2026 is a timely, regulatory-mandated snapshot that should be used as a corroborative data point rather than the sole basis for trading decisions. Combine the 13F with higher-frequency flow and derivatives data to form actionable insights.

FAQ

Q: How current is the information in a Form 13F filed on April 15, 2026?

A: The filing lists holdings as of March 31, 2026, so the data are a quarter-end snapshot; the SEC requires 13Fs to be filed within 45 days after quarter-end (SEC Rule 13f-1), making the April 15 filing timely but necessarily backward-looking.

Q: Can a manager appear long in a 13F but actually be market-neutral?

A: Yes. 13Fs omit most derivatives and short positions, so a manager can hold disclosed long equities while offsetting exposure with futures, swaps or shorts—meaning net economic exposure may be very different from the 13F long-only picture. To resolve this, cross-reference options open interest, swap disclosures (where available), and daily fund NAV and flow data.

Q: How should institutional investors incorporate a 13F from an issuer like Tema ETFs into their workflow?

A: Use the 13F as a hypothesis generator—identify material deltas and then validate them via higher-frequency channels (daily NAVs, fund flows, options and futures markets, and direct sponsor communications). Cluster the filing against peer 13Fs to assess whether a move is idiosyncratic or indicative of broader rotation.
