## Overview
Every quarter, institutional investors managing over $100M in U.S. equities are required to disclose their holdings to the SEC via Form 13F. Q1 2026 filings cover positions held as of **March 31, 2026** — and they'll be released starting **May 15, 2026**.
This page tracks what to expect: which managers to watch, key themes likely to emerge, and how to use 13F data to get ahead of the crowd.

## 📅 Q1 2026 13F Filing Dates
| Milestone | Date |
|-----------|------|
| Q1 2026 quarter end | March 31, 2026 |
| SEC filing deadline | **May 15, 2026** |
| Expected first filings | May 15, 2026 (large filers often file early) |
| Filing rush window | May 15–19, 2026 |
| Late stragglers | Up to May 15 EOD (some file same-day) |
| Full data available on 13F Insight | Within hours of SEC release |
**How it works:** Institutional managers have 45 days after quarter-end to file. Q1 ends March 31, so the deadline is May 15. The SEC's EDGAR system publishes filings in near real-time as they're submitted.
---
## 🔭 Key Managers to Watch
### 1. Berkshire Hathaway (Warren Buffett)
**AUM:** ~$350B+ equity portfolio
**Why it matters:** Berkshire's Q4 2025 filing showed continued concentration in Apple and Occidental Petroleum, with new mystery positions held via confidentiality requests. Q1 2026 will reveal whether those positions were disclosed — and whether Buffett trimmed or added to his energy bets as oil prices shifted.
**Watch for:**
- Confidential holding disclosures from Q4 2025
- Any changes to Apple position (previously trimmed)
- Moves in financials (Bank of America stake direction)
- New positions in industrials or consumer staples
---
### 2. Millennium Management (Izzy Englander)
**AUM:** ~$70B+ in 13F holdings (multi-strategy)
**Why it matters:** Millennium's thousands of positions act as a leading indicator of quant/multi-strat crowding. When Millennium reduces a sector, it often signals consensus unwinding before the market notices.
**Watch for:**
- AI-adjacent tech (NVIDIA, AMD, Broadcom) position sizing
- Changes in healthcare after Q4 biotech volatility
- Energy and commodity exposure shifts
- Any sudden exits in previously crowded mid-caps
---
### 3. Bridgewater Associates (Ray Dalio / co-CIOs)
**AUM:** ~$20B+ in 13F equity holdings
**Why it matters:** Bridgewater's All Weather and Pure Alpha strategies tend to hold emerging market ETFs and commodity-sensitive equities. Their Q1 2026 positioning will reflect macro calls on dollar strength, China exposure, and inflation hedges.
**Watch for:**
- GLD (gold ETF) and commodity positions
- Emerging market equity ETF changes
- Any rotation toward or away from defensive sectors
- U.S. large-cap index exposure adjustments
---
### 4. Appaloosa Management (David Tepper)
**AUM:** ~$6–8B in 13F holdings
**Why it matters:** Tepper is one of the most followed contrarian macro traders. His Q4 2025 comments about reducing equity exposure made headlines. Q1 2026 will show whether he followed through — or doubled down amid volatility.
**Watch for:**
- Overall equity reduction vs. Q4 2025 levels
- China ADR positions (he's historically been bullish on China names)
- Any new concentration bets in beaten-down sectors
- Financial sector (his historical stronghold)
---
### 5. D.E. Shaw & Co.
**AUM:** ~$90B+ in 13F holdings
**Why it matters:** D.E. Shaw operates some of the largest quantitative trading operations globally. Their 13F holdings reflect systematic factor exposures. Large position changes often signal factor rotation or risk-on/risk-off regime shifts.
**Watch for:**
- Momentum vs. value factor tilt changes
- AI/semiconductor concentration vs. Q4 2025
- Small-cap vs. large-cap allocation shifts
- Any new sector concentrations not seen in prior quarters
---
### 6. Tiger Global Management (Chase Coleman)
**AUM:** ~$12–15B in 13F holdings
**Why it matters:** Tiger Global was one of the hardest-hit funds during the 2021–2022 tech drawdown and has been rebuilding. Their Q1 2026 positioning will signal whether the "Tiger cub" recovery thesis is playing out — and where they see value in growth tech.
**Watch for:**
- Recovery of tech/internet positions vs. previous concentration
- Any new AI infrastructure bets
- International tech exposure (India, Latin America)
- Whether lock-up-driven selling pressure has eased
---
## 📊 Key Themes to Watch in Q1 2026
### Theme 1: AI Concentration — Peak or Pivot?
The "Magnificent 7" AI trade drove outsized returns through much of 2024–2025. By Q1 2026, institutional positioning in NVIDIA, Microsoft, Alphabet, and Meta had become crowded to historic levels.
**The Q1 2026 question:** Did institutional investors continue to pile in, or did rising valuations trigger de-risking?
**Signals to watch:**
- Top-10 holding concentration in mega-cap tech
- New entrants to AI infrastructure (power, data centers, cooling)
- Rotation from AI software to AI hardware plays
- Any coordinated reduction by multi-strat funds (de-crowding signal)
---
### Theme 2: Sector Rotation — Where Did the Money Go?
Q4 2025 showed early signs of rotation from growth tech into industrials, energy, and healthcare. Q1 2026 filings will confirm whether this was a temporary move or a structural shift.
**Rotation candidates:**
- **Into:** Defense/aerospace, energy infrastructure, financials (yield plays)
- **Out of:** High-multiple SaaS, unprofitable growth, consumer discretionary
- **Wildcard:** China ADRs — geopolitical risk vs. valuation opportunity
---
### Theme 3: De-Crowding Signals
When multiple large funds reduce the same position simultaneously, it creates what analysts call "de-crowding" — and it can accelerate sell-offs. 13F data is one of the few ways to detect this in near real-time (with a 45-day lag).
**Q1 2026 de-crowding candidates to monitor:**
- Mega-cap tech (if multiple top-20 funds trim simultaneously)
- Biotech ETFs (after Q4 2025 sector volatility)
- Retail-facing consumer names
- Any name where short interest AND 13F holders both decline
---
### Theme 4: New Positions & Emerging Convictions
Every quarter, 13F filings reveal "new money" — positions that weren't there before. These are often the most actionable signals, as they represent fresh institutional conviction rather than legacy holdings.
**What we're watching for:**
- Nuclear/energy infrastructure (trending institutional narrative)
- Defense tech (geopolitical tailwinds)
- India-focused equities (secular growth story)
- Any coordinated new buying across 3+ top-20 managers
---
## 🔍 Frequently Asked Questions
### When do Q1 2026 13F filings come out?
Q1 2026 13F filings are due **May 15, 2026** — exactly 45 days after the March 31 quarter-end. Most major institutions file between May 15–19. Berkshire Hathaway, Bridgewater, and other large managers typically file within the first few days of the window.
### What is a 13F filing?
A Form 13F is a quarterly report required by the SEC for institutional investment managers with over $100 million in qualifying U.S. equities. It discloses every long position held at quarter-end. 13F filings do not include short positions, international holdings, or some OTC derivatives.
### How do I find Q1 2026 13F filings?
You can search the SEC's EDGAR database directly at sec.gov, or use platforms like [13F Insight](https://13finsight.com) that aggregate, normalize, and make filings searchable immediately as they're released — often hours before major financial media covers them.
### What does 13F data tell you about the market?
13F data reveals institutional positioning, concentration, and sentiment with a 45-day lag. It's most useful for:
- Identifying crowded trades (many funds in the same name)
- Spotting emerging themes before they're widely covered
- Tracking smart-money conviction vs. fast money rotation
- Flagging de-crowding risk in high-momentum names
### Can I trade based on 13F filings?
13F data is historical (45-day lag), so it's not suitable for short-term trading. It's most valuable for understanding structural positioning, confirming investment theses, and identifying research angles before the broader market prices them in.
### Which managers file the most interesting 13F reports?
The most-followed filers include Berkshire Hathaway (for Buffett's concentrated bets), Millennium (for broad market signals), and "Tiger cub" funds like Tiger Global and Coatue for tech/growth positioning. Less-followed but high-signal filers include Appaloosa (macro), D.E. Shaw (quant factors), and smaller concentrated funds with 10–30 positions.
### How often do 13F filings happen?
Four times per year, covering each calendar quarter:
- Q1 (Jan–Mar): due May 15
- Q2 (Apr–Jun): due August 14
- Q3 (Jul–Sep): due November 14
- Q4 (Oct–Dec): due February 14
