XLK ÷ SPY, 10-year range, as of Jul 17, 2026
How the reading moved
These changes re-score an older XLK÷SPY ratio against today's 10-year window, so they show whether the relative price has drifted toward the highs or lows of its own history — not a peer ranking and not a return forecast.

What moves this
XLK's weight is concentrated in a handful of mega-cap platform and semiconductor companies, so its relative price tends to move in large steps around shifts in the market's view of AI and cloud spending, rather than drifting gradually the way a more diversified sector does.
FAQ
Why does the technology sector's relative price move in such large jumps?
A small number of companies make up a large share of the index, so a re-rating of any one of them shows up directly in the sector-wide ratio — this sector is less diversified than its size suggests.
Does a high percentile here mean the sector is overpriced?
It means the price relative to the S&P 500 is high compared to this sector's own past 10 years — it says nothing about whether current earnings growth justifies that level.
Why compare technology to the S&P 500 instead of to another sector?
Comparing PE levels across sectors with different growth and capital structures produces misleading conclusions; comparing a sector only to its own history avoids that problem entirely.
