Most Of GE Aerospace’s Return Has Not Come From The Market You Own

Its five-year correlation and its return gap say most of this has been the company’s own story, and the capture readings say you will feel every market swing along the way.

GE Aerospace (GE) has gained 6.7% over the past five trading days while the S&P 500 has slipped 1.1%, one name pulling away from a falling market. The run overlapped the Farnborough Airshow, where the company announced the world’s first high-altitude flight assisted by hybrid-electric propulsion, though one announcement cannot explain the move.

The instinct when a holding outruns a falling market is to buy the strength. What decides your wealth is not where this trades a week from now. It is how much of its return has been its own story rather than the market you already own through an index fund, and what holding it does to the swings you sit through.

At A Correlation Of 0.59, How Much Of This Is Really GE?

Over the past five years GE has tracked the S&P 500 at a correlation of 0.59. A reading of 1.0 would mean lockstep with the index; 0 would mean no relationship. At 0.59 it takes part of its direction from the market and keeps a substantial amount of its own, and the total return is where the money has been: 42% annualized over five years against 12.7% for the S&P 500.

The temptation is to treat a low correlation as the goal. It is not. Gold, at a correlation of only 0.09 to GE, is the purest diversifier here, but it compounded at just 17.0% a year over the same stretch, less than half GE’s rate. Real estate managed 2.9% a year at a 0.4 correlation to GE. What is scarce is strong returns with real independence, and the risk-adjusted math backs GE: a five-year Sharpe ratio of 1.16 against 0.57 for the index. Correlation, though, is only half the risk picture.

What Capture Of 126% And 112% Feels Like To Hold

Over the past year, on days the S&P 500 rose, GE captured about 126% of the market’s gain, and on days the index fell it absorbed about 112% of the market’s loss. In plain terms, a 1% up day for the index has tended to mean roughly 1.3% for GE, and a 1% down day roughly 1.1%.

The two readings sit close together, so the amplitude is the story: this holding amplifies both directions. Annualized volatility of 31% against 17.1% for the S&P 500 over the past five years points the same way. The capture readings are a one-year measure, taken from a stretch in which the stock returned 35% over the trailing twelve months, and they can shift with the business underneath them.

Is The Aftermarket Still Feeding That Return?

In its second quarter 2026 GE reported revenue up 24%, EPS up 22% and free cash flow up 43%, and lifted full-year 2026 guidance across the board, to $7.65-$7.85 of EPS and $8.9 billion-$9.2 billion of free cash flow. Behind that sits a commercial services backlog of roughly $170 billion, up nearly $30 billion since the end of 2024.

The constraint is not demand. By the company’s own account supply is the harder problem, and its numbers agree: spare parts delinquencies, shipments held up by material availability, grew 20% sequentially in the second quarter. Total operating margin narrowed 130 basis points to 22%, which the company tied to installed engine growth, investments and inflation. The stock is not cheap, at 42.1 times earnings against an S&P 500 median of 24.4, though trailing revenue growth of 22% against a 7.8% median explains much of that.

Own It For The Aftermarket Cycle, Not For A Calm Ride

A correlation of 0.59 beside a 42% annualized return is not a flaw to argue away. It is the profile most portfolios lack: a return stream only partly the index in disguise. The price sits in the amplitude: roughly a quarter more than the market on good days and slightly more on bad ones too. The number to watch is spare parts delinquency, because supply, not demand, turns that backlog into revenue. If you are judging how wide the coming weeks could swing, the size of the move the market is already pricing in beats any single week’s return.

Owning The Aftermarket Cycle Is Not The Same As Owning A System

A holding that outruns the index going up and going down is a passenger in your portfolio’s swings, not a brake on them. The braking comes from how the rest of the money is arranged: what you own, in what weight, and what changes it. The Trefis High Quality (HQ) Portfolio is built for that job, holding a basket of quality names and rebalancing with rules. It has a track record of outpacing a benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
