The Communication Services Select SPDR Fund (XLC) has a 9% weighting within the S & P 500, which is smaller than its growth sector counterparts: XLK Technology (30%) and XLY Consumer Discretionary (10%). But XLC’s future path is extremely important for the general market’s prospects. XLC is heavily driven by three major growth stocks: Meta (META) , Netflix (NFLX) and Alphabet (GOOGL) make up a combined 36% of the ETF. NFLX (which we profiled here on 4/10) has been outperforming for months and just blasted to new all-time highs after reporting earnings on 4/17. GOOGL is trading higher so far Friday after its earnings report, but it remains noticeably below its own highs. META releases its quarterly numbers next Wednesday, 4/30. And while it’s off its April lows, it, too, has a lot of ground to make up. Both GOOGL and META remain below their respective 200-daymoving averages. All of that being the case, XLC finds itself smack-dab in the middle of a major battleground. The ETF is hovering near an impending breakout from a potential three-week cup-and-handle pattern. That’s constructive, but the formation has taken shape right BENEATH the bearish head-and-shoulders pattern that it broke below earlier this month. The ETF also is battling its 200-day moving average, which aligns with the 50% retracement of the entire February–April decline (not shown). From an indicator perspective, its 14-day RSI has popped back to the 50-midpoint, a level that it would need to eventually overcome for momentum to truly flip back to positive. Simply stated, A LOT is riding on how XLC resolves this zone. And it’s not alone — the S & P 500, the Nasdaq-100 and many other key indices and ETFs are in similar setups after snapping back from the February-April market-wide waterfall decline. Zooming out, we can see how closely aligned the XLC ETF has been with the S & P 500 since 2019. XLC had a strong run off the COVID lows but topped out a few months before the S & P 500 did in 2021. Eventually, the S & P followed suit, with both the index and ETF declining through most of 2022. After the late-2022 low, XLC and the SPX followed a similar trajectory on the way up through just a few months ago. Most recently, both XLC and the S & P 500 topped around the same time this past February and have taken similar paths in recent weeks, attempting to rebound. One thing is clear: the very consistent uptrend that had been in place for over two years — from October 2022 through February 2025 — is no longer valid for XLC and the SPX. When XLC’s upward-sloping trading channel was broken at the end of 2021, it led to the broader 2022 market decline. To avoid a similar outcome this time, XLC needs to do a better job of building on budding bullish patterns – like the one we just reviewed above. If it can, that would suggest that its largest components are performing well and leading — just as they did during the previous, two-year advance. And given how influential these companies are to the broader market, their potential strength (or weakness) will have a meaningful impact on the S & P 500. — Frank Cappelleri Founder: https://cappthesis.com Get Your Ticket to Pro LIVE Join us at the New York Stock Exchange!
