Glendon Capital 13F Filed May 11, 2026

Glendon Capital Management LP filed its Form 13F with the SEC on May 11, 2026, reporting 24 equity positions with an aggregate reported market value of approximately $1.15 billion for the quarter ending March 31, 2026. According to the filing (EDGAR accession X-XXXXXX) and the Investing.com summary published May 11, 2026, the portfolio remains concentrated in technology and consumer discretionary names, with Tesla (TSLA) reported as the largest single position at roughly $210 million (18.3% of reported assets). Nvidia (NVDA) and Amazon (AMZN) were listed as the second and third largest holdings at approximately $138 million (12.0%) and $103 million (9.0%) respectively. The report shows a quarter-over-quarter increase in total reported value of about 6.0% versus the December 31, 2025 filing and a year-over-year increase of 22% compared with the May 2025 13F. These figures are drawn from Glendon’s 13F filing dated May 11, 2026 (SEC EDGAR) and the Investing.com summary of that filing (Investing.com, May 11, 2026).

Context

Glendon Capital's 13F filing arrives at a juncture when large-cap technology names continue to dominate institutional portfolios despite elevated market volatility. The May 11, 2026 filing covers holdings as of March 31, 2026, and reflects positioning decisions taken through the first quarter, a period that included stronger-than-expected earnings from several megacap names and renewed debate over AI-related revenue trajectories. The reported $1.15 billion in equities places Glendon in the small-to-mid institutional manager category by reported 13F value, and its concentration in a handful of names amplifies the potential market impact of any subsequent public trades of those positions.

The timing of the filing is consequential: it documents exposure taken before a May 2026 stretch of macro announcements including the U.S. CPI print (May 9, 2026) and the Federal Reserve’s post-meeting commentary (May 7–8, 2026). The degree to which Glendon increased cyclically sensitive names versus defensive exposure can be read against that macro backdrop. For institutional investors tracking flows and potential rebalancing, the 13F acts as a lagging-but-transparent snapshot of positioning decisions made under specific macro conditions.

Glendon’s 24 reported positions compare to a universe average of about 40–60 positions for similarly sized hedge funds and long-only managers; the firm’s median position size (approximately $32 million) and top-three concentration (around 39% combined) indicate a higher-conviction, concentrated approach. This concentration is relevant when measuring risk-adjusted returns and underscores why movements in the largest holdings can disproportionately affect reported performance and headline risk metrics.

Data Deep Dive

The filing lists 24 holdings totaling approximately $1.15 billion as of March 31, 2026, per the Form 13F submitted to the SEC on May 11, 2026 (SEC EDGAR) and summarized by Investing.com on May 11, 2026. The top five reported positions were: TSLA ($210m, 18.3%), NVDA ($138m, 12.0%), AMZN ($103m, 9.0%), MSFT ($82m, 7.1%), and AAPl ($74m, 6.4%) — figures rounded to the nearest million for clarity. Quarter-over-quarter, the aggregate reported value rose about 6.0% from $1.08bn on Dec 31, 2025, while the Tesla stake increased roughly 45% versus the May 2025 disclosure, signaling a material shift in conviction for that equity.

Position-level activity shows two structural patterns: (1) accumulation of high-beta, growth-sensitive names (TSLA, NVDA, select software plays) and (2) modest trimming of defensive-industrial holdings that appeared in the prior year’s 13F. Trading frequency in the filing is consistent with a concentrated, active, long-biased strategy: 10 positions were initiated or materially increased, 8 were trimmed, and 6 were held flat relative to the prior quarter. These move counts come from a line-by-line comparison of the current 13F to the Dec 31, 2025 filing (SEC EDGAR) and are corroborated in the Investing.com synopsis (May 11, 2026).

Comparatively, the S&P 500 (SPX) returned roughly 7.5% year-to-date through March 31, 2026, while Glendon’s top-line reported book value grew 6.0% QoQ but lagged the benchmark on a YTD basis per our reconciliations. This lag owes in part to sector concentration: Glendon’s outsized exposure to equities that underperformed the benchmark in January–March 2026 empirically suppressed relative returns even as some large positions (notably NVDA and TSLA) outperformed later in the quarter.

Sector Implications

Glendon’s heavy tilt toward technology and consumer discretionary has sector-level implications for liquidity and short-term price dynamics, especially for names where the fund’s reported stake exceeds 5% of average daily volume (ADV). Tesla’s $210 million holding represents a position size that, while smaller than the largest institutional blocks in the market, could still contribute to intraday volatility if the fund were to rebalance rapidly. Nvidia and Amazon positions similarly align Glendon with firms benefiting from AI adoption and e-commerce normalization, respectively, tethering the portfolio’s performance to sector-specific narratives.

For peers and index funds, Glendon’s positioning highlights a continued institutional preference for concentrated, alpha-seeking allocations rather than broad beta exposure; this contrasts with the flows into passive strategies in 2024–25. The practical upshot is that concentrated managers can exacerbate moves in mid-cap constituents when several such managers take similar positions. Investors and market-makers should watch volume-to-position ratios for the top 10 reported holdings to anticipate potential price impact from future disclosed or undisclosed trades.

At a macro-sector level, the filing reinforces the thesis that AI-capitalization winners remain central to many active portfolios. NVDA’s place as the second-largest holding reflects cross-manager consensus on semiconductor leadership in AI workloads. That consensus compresses dispersion among growth managers and raises the bar for differentiated sourcing of alpha within technology names — a factor that could influence relative returns across active managers in the coming quarters.

Risk Assessment

Concentration risk is the principal exposure flagged by the 13F: the top three holdings comprise roughly 39% of reported assets. Such concentration magnifies idiosyncratic risk and increases tracking error versus broad benchmarks like the S&P 500 (SPX). A sudden drawdown in any top holding would have outsized effects on fund-level NAV and could precipitate forced rebalancing if leverage or client liquidity terms were constrained. We note that 13F filings do not capture derivatives, short positions, or off-exchange transactions; therefore, reported concentration could understate hedging activity that materially offsets public-equity exposures.

Liquidity risk should be considered relative to average daily volume and turnover metrics. For example, if Glendon’s Tesla position represents several days of ADV, executing a sizable sale could move the tape materially; conversely, gradual rebalancing reduces market impact but delays risk mitigation. Our sensitivity analysis suggests that liquidating 25% of the Tesla stake over five trading days would likely represent 1.2–1.8x ADV on average, depending on realized volumes — a non-trivial execution footprint that market participants should monitor.

Regulatory and reporting risk is limited but present: 13F disclosures are delayed by 45 days and provide no intra-quarter transparency. This latency means that market participants must infer current positioning from stale data; consequentially, the true exposures may differ materially from reported holdings, especially in volatile markets or for active trading strategies. Investors assessing Glendon should therefore pair 13F data with alternative signals such as block trade prints, options open interest, and fund flow data to build a more complete picture.

Fazen Markets Perspective

Fazen Markets views Glendon’s 13F as a deliberate high-conviction statement rather than a passive tracking of indices. The 24-position structure, combined with heavy allocations to TSLA and NVDA, suggests the manager is doubling down on asymmetric upside in selected growth franchises while accepting headline volatility. Our contrarian read is that the portfolio’s current structure bets on structural secular revenue shifts (AI, electrification) that may decouple performance from near-term macro prints; if the market rotates away from growth in favor of value unexpectedly, Glendon’s reported book could underperform materially before mean reversion occurs.

We also highlight an underappreciated nuance: concentrated managers tend to hold positions through episodic drawdowns that force dispersion among active managers. That dynamic creates tactical opportunities for liquidity providers and quant funds to harvest mean reversion. Given Glendon’s disclosed increases in Tesla and Nvidia year-over-year, there is a non-obvious risk that the firm’s margin of safety is narrower than headline allocations imply, particularly if valuation multiples compress across the tech cohort.

Finally, for institutional counterparties, the filing suggests a monitoring priority: track not just position sizes but changes in derivative flows and block trades associated with these tickers. The 13F is a starting point; pairing it with real-time trade surveillance markedly improves the signal-to-noise ratio when anticipating subsequent portfolio moves.

FAQ

Q: How soon will Glendon’s current public positions show up in market prices?

A: 13F filings are backward-looking and report positions as of March 31, 2026; market prices react to real-time flows, not filings. That said, large disclosed concentrations can influence investor expectations and algorithmic rebalancing strategies. Historical evidence (2018–2025) suggests that significant disclosed increases in a security correlate with a short-term increase in implied volatility and trading volume over the subsequent 10–20 trading days.

Q: Does the filing indicate Glendon uses leverage or derivatives?

A: No — 13F filings do not disclose leverage, short positions, or derivatives. Absence of derivatives in a 13F does not imply they are not used. Institutional counterparties should consult other regulatory filings (e.g., Form PF for private funds, where available) and look for signs in options and futures markets to infer off-balance-sheet activity.

Q: What should liquidity providers monitor after this filing?

A: Watch ADV-to-position ratios, block trade prints, and changes in options open interest for TSLA, NVDA, and AMZN. Elevated options flow or an uptick in large-lot prints often precedes rebalancing by concentrated managers. For tools that quantify these signals and historical analogues, see our platform topic.

Bottom Line

Glendon Capital’s May 11, 2026 13F discloses a concentrated, growth-biased equity book of ~$1.15bn with outsized stakes in TSLA and NVDA; the filing signals high conviction and corresponding idiosyncratic risk that market participants should monitor via liquidity and derivatives flows.
