So, the Energy Select Sector SPDR Fund (XLE) has now done something it's never done before: it's closed higher for 14 straight weeks. That's the longest winning streak in the history of the fund. But that's just the start of why this is interesting.
Think about it this way: measured against every other S&P 500 sector's best run ever, XLE now finds itself in extremely exclusive company. Only two funds have ever sustained 14 or more consecutive weeks of gains. XLE is one of them. And it's just one week away from tying a record that hasn't been touched in over a decade.
To put that in perspective, the last time any S&P 500 sector ETF had a streak this long, Barack Obama was in the first months of his second term, the iPhone 5 was the hot new gadget, and "Thrift Shop" by Macklemore & Ryan Lewis was topping the charts. That was April 2013. XLE is knocking on that door.
What Does a 14-Week Streak Actually Mean?
A weekly winning streak for a sector ETF is pretty straightforward: it means the fund closed higher each Friday than it did the Friday before. No down weeks, no flat weeks. Just up, up, and up again. Doing that for 14 weeks in a row, through all the usual market noise—economic data, Fed decisions, random bear raids—is a statistical rarity. It's the market equivalent of a perfect game.
The only other sector fund to ever match this 14-week run is the Technology Select Sector SPDR Fund (XLK), which did it back in April 2012 during the post-financial-crisis tech rally.
The outright champion, however, is the Utilities Select Sector SPDR Fund (XLU). It managed 15 straight weekly gains, ending in April 2013. That streak was fueled by a defensive rotation, as investors piled into dividend-yielding utilities to hedge against equity market volatility. That record has stood, unchallenged, for 13 years. XLE is now one good week away from a tie.
Just How Rare Is This?
Let's be clear: sustained sector-wide rallies of this length are vanishingly rare. The history of the S&P 500 sector SPDR funds shows just two instances of a 14-week streak before now. XLE has joined XLK in that club and is staring at the door to XLU's record territory.
Here’s a look at the maximum weekly winning streaks for all the S&P 500 sector SPDRs:
| S&P 500 Sector | Max Weekly Streak | Set In |
|---|
| Utilities Select Sector SPDR Fund (XLU) | 15 | April 2013 |
| Energy Select Sector SPDR Fund (XLE) | 14 | 2026 |
| Technology Select Sector SPDR Fund (XLK) | 14 | April 2012 |
| Consumer Discretionary Select Sector SPDR Fund (XLY) | 13 | July 2013 |
| Health Care Select Sector SPDR Fund (XLV) | 11 | February 2004 |
| Communication Services Select Sector SPDR Fund (XLC) | 10 | December 2019 |
| Materials Select Sector SPDR Fund (XLB) | 10 | March 2024 |
| Financial Select Sector SPDR Fund (XLF) | 10 | April 2010 |
| Consumer Staples Select Sector SPDR Fund (XLP) | 9 | August 2020 |
| Industrial Select Sector SPDR Fund (XLI) | 9 | March 2024 |
| Real Estate Select Sector SPDR Fund (XLRE) | 9 | August 2021 |
As you can see, most sectors top out at 10-13 weeks. Breaking into the 14-15 week club is exceptional.
Why Is Energy Doing This, and Why Now?
Here's a crucial detail: this streak didn't start with the recent geopolitical headlines. XLE has closed higher every single week since December 22, 2025. That's more than two full months before U.S.-Iran tensions escalated in early March. The takeaway? The underlying bid for energy stocks was already in place, a structural trend moving on its own steam.
What the conflict did was act as an accelerator. The prospect of disruptions to the Strait of Hormuz—a chokepoint for about 20% of the world's seaborne oil supply—layered a tangible physical supply shock on top of a rally that frankly didn't need a geopolitical catalyst to keep going.
Oil prices jumped on that supply-risk premium, which in turn lifted revenue and earnings expectations for the big integrated oil companies, the exploration and production firms, and the oilfield services providers that make up the bulk of XLE's holdings. The war didn't start the party, but it definitely brought stronger drinks.
Okay, So What Are the Risks?
Fourteen weeks of gains have a way of making everyone a believer. Energy is now arguably the most consensus long trade in the equity market. And that concentration is itself a risk. When everyone is on one side of the boat, even a small shift can feel dramatic.
Since the war began, energy stands alone as the only S&P 500 sector in positive territory. XLE is up about 9% over that period. Meanwhile, the broader market, as tracked by the SPDR S&P 500 ETF Trust (SPY), is down about 6%. Energy has been the lifeboat in a choppy sea.
The problem with being the lifeboat is that you're most valuable when the sea is rough. A ceasefire or a diplomatic agreement between the U.S. and Iran would likely remove the supply-shock premium that has powered this second, sharper leg of the rally. And if that premium vanishes, there isn't much of a cushion left from a valuation perspective.
Speaking of valuation, that's another thing that's changed. Energy stocks now trade at about 21 times forward earnings. The broader S&P 500 trades at about 22 times. The sector's long-standing discount to the market—which has been one of the most reliable and repeated bullish arguments for energy over the past several years—has effectively disappeared. That historical tailwind is gone.
So, we're left with a historic streak, driven by a mix of pre-existing strength and a geopolitical turbocharge, that has made energy the market's darling while simultaneously eroding its traditional margin of safety. It's a fascinating moment. The question for investors isn't just whether the streak continues for a record-tying 15th week, but what happens the week after that, whenever it finally comes.
