Who Is Buying RTX (Raytheon)? Hedge Fund Activity in 2026

RTX Corporation — the defense and aerospace conglomerate formed from the merger of Raytheon and United Technologies — stands as one of the most diversified plays in the defense sector. With businesses spanning Pratt & Whitney jet engines, Raytheon missile systems, and Collins Aerospace avionics, RTX touches virtually every aspect of modern military and commercial aviation. The latest 13F filings reveal that institutional money managers are heavily tilted toward accumulation.

Of the 13 major funds actively holding RTX, 6 are buying while only 1 is selling. That 6-to-1 buy-sell ratio makes RTX one of the most consensus bullish defense names in our tracking universe — a sharp contrast to the bearish sentiment surrounding peer Lockheed Martin.

Institutional Activity at a Glance

• Funds Buying: 6
• Funds Selling: 1
• Funds Holding: 6
• Active Funds Tracked: 13 of 35

A 6-to-1 buy-sell ratio is a strong bullish signal, particularly when it spans both quantitative and fundamental strategies. The fact that 6 additional funds are holding steady suggests broad institutional comfort with RTX at current levels.

Who's Buying RTX?

The buyer list features some of the most influential names in institutional investing:

Appaloosa Management holds $244 million and increased its position. David Tepper's fund has been selectively adding to defense exposure, and RTX's diversified business model — spanning both defense and commercial aerospace — aligns with Appaloosa's preference for companies with multiple growth vectors. Unlike a pure-play defense name, RTX benefits from the commercial aviation recovery through Pratt & Whitney.

Citadel Advisors increased to $205.5 million. Ken Griffin's multi-strategy giant has been actively building its RTX position, likely driven by both fundamental analysis and quantitative signals pointing to continued revenue growth. Citadel's involvement at this scale reflects genuine conviction from one of the world's most sophisticated trading operations.

D.E. Shaw holds $107.2 million and increased. Shaw's quantitative models consistently identify value in defense names with strong order backlogs, and RTX's massive multi-year backlog exceeding $200 billion provides exactly the kind of revenue visibility that quant models favor.

Renaissance Technologies initiated a NEW $51.3 million position. The legendary Medallion fund's parent opening a fresh position in RTX is a notable data point. Renaissance processes more data points than virtually any other fund, and their entry suggests statistical patterns favoring RTX at current price levels.

Two additional funds also increased their positions, creating a broad-based buying wave across different investment styles and philosophies.

Who's Selling RTX?

The selling side is remarkably thin:

Millennium Management is the sole seller among tracked funds. Israel Englander's pod-based hedge fund reducing exposure likely reflects portfolio-level risk management rather than a fundamental bearish view on RTX specifically. Millennium's structure means individual portfolio managers make independent decisions, and a reduction in one pod doesn't necessarily reflect the firm's overall view.

Having only a single seller out of 13 active funds is an exceptionally clean institutional picture — one of the cleanest buy-sell ratios in our entire coverage universe.

Notable Moves

Renaissance Technologies' NEW $51.3 million position is the headline move. When Jim Simons' organization — which has generated the highest risk-adjusted returns in hedge fund history — initiates a new position, the market takes notice. Renaissance entering RTX fresh while the broader defense sector sees mixed institutional sentiment suggests their models have identified something specific about RTX's risk-reward profile.

The Appaloosa-Citadel-D.E. Shaw trifecta all increasing simultaneously is also significant. These three firms represent very different investment approaches — Tepper's macro-driven value investing, Griffin's multi-strategy approach, and Shaw's pure quantitative methods — yet all three are converging on the same bullish RTX thesis. When diverse methodologies reach the same conclusion, the signal strengthens considerably.

The 6 funds holding steady is equally telling. In a market where defense stocks are seeing significant institutional churning, the fact that nearly half of RTX's institutional holders maintained their positions without selling suggests deep confidence in the company's trajectory.

What This Signals

RTX enjoys one of the strongest institutional consensus positions in the defense sector. The 6-to-1 buy-sell ratio, combined with 6 funds holding, paints a picture of broad institutional confidence driven by several structural advantages.

First, RTX's diversification is a genuine differentiator. While pure-play defense names face binary risk around government budget cycles, RTX's Pratt & Whitney division benefits from the secular recovery in commercial aviation. Airlines are ordering new fuel-efficient aircraft at record rates, and Pratt & Whitney's geared turbofan engines power many of these next-generation planes. This commercial exposure provides a natural hedge against defense spending uncertainty.

Second, RTX's order backlog exceeding $200 billion provides multi-year revenue visibility that de-risks the investment thesis. Institutional investors — particularly quantitative funds — love predictable revenue streams, and RTX's backlog is one of the deepest in the aerospace industry.

Third, the company's margin expansion story is just beginning. Post-merger integration costs are declining, and RTX is starting to realize the synergies promised when Raytheon and United Technologies combined. Improving margins on a growing revenue base is the recipe for earnings beats that attract even more institutional capital.

The lone seller — Millennium — appears to be an outlier driven by portfolio-level considerations rather than a fundamental bear case. When 12 out of 13 tracked funds are either buying or holding, individual investors should take note: smart money is solidly behind RTX.

FAQ

Why is RTX considered more diversified than other defense names?

RTX combines defense businesses — Raytheon missiles and defense systems, Collins Aerospace avionics — with Pratt & Whitney commercial jet engines. That gives revenue exposure to both government defense budgets and the commercial aviation cycle. Many institutional buyers cite this dual exposure as a reason the name screens differently from pure-play primes.

How important is the multi-year backlog for the bull case?

RTX's reported backlog has been in the $200B+ range, providing several years of revenue visibility on existing contracts. Quantitative funds in particular tend to favor names with predictable, contracted revenue streams. Backlog conversion timing is still subject to supply chain and execution risk, which is why the bull case is "high visibility," not "guaranteed."

What is the Pratt & Whitney GTF issue and why does it matter?

Pratt & Whitney's geared turbofan engine family has been working through a multi-year inspection and repair program tied to powder metal issues, which has driven aircraft on ground (AOG) headlines and large charges in recent years. Resolution pace affects RTX cash flow, customer compensation, and margin trajectory. Many institutional notes specifically flag this as the key risk to the otherwise bullish setup.

Why is a "NEW" Renaissance Technologies position notable here?

Renaissance opened a fresh ~$51.3M RTX position in the reported quarter, which on a 13F means they previously had no disclosed long position. Their systematic process tends to take positions when statistical signals align — value, momentum, quality, etc. — so a new entry is read as another independent signal, not as a fundamental endorsement.

Is heavy institutional buying a green light for individual investors?

A 6:1 buy/sell ratio is unusually clean, but 13Fs are backward-looking and do not capture hedges, options, or shorts. The signal is useful for understanding sentiment and flow, not as a substitute for evaluating valuation, your time horizon, and your own risk tolerance. Treat it as one informational input among several.
