Nasdaq 100 ETF (QQQ)

QQQ is the Invesco Nasdaq-100 ETF. It holds the 100 largest non-financial companies listed on the Nasdaq, weighted by modified market cap. The Magnificent Seven account for roughly 50% of QQQ weight in 2026, so the fund is best understood as a concentrated mega-cap-tech vehicle rather than a diversified equity index. QQQ is the second-largest US equity ETF after SPY by AUM and trades roughly $20 billion of average daily volume.

Why it matters: QQQ is the high-beta long-duration leg of the equity market. Long duration in equity terms means cash flows weighted heavily into the future, which makes QQQ unusually sensitive to changes in real rates and to the AI capex cycle. Daily realized volatility runs about 6.86% versus 5.58% for SPY, so QQQ is a leveraged play on whatever is driving SPY plus an idiosyncratic AI/semiconductor factor. When semis (SMH) and software diverge, QQQ tells you which side is winning.

In April 2026 QQQ is trading near all-time highs alongside SPY, with the Nasdaq-100 led by NVDA, MSFT, GOOG, and META on AI capex and cloud revenue acceleration. The index is more expensive than SPY on every conventional multiple: forward P/E in the high-20s versus SPY low-20s, justified by roughly 600bp higher expected earnings growth but vulnerable to any real-rate shock.

The macro backdrop favours QQQ on rate cuts (the Fed held at 3.50-3.75% on April 29 with four dissenters voting for cuts) and disfavours it on inflation surprises (CPI 3.3% headline). The 10Y TIPS at 1.93% is the cleanest single anchor for the multiple. The August 5, 2024 episode (VIX intraday 65, QQQ -6% intraday during the yen carry-trade unwind) is the recent template for what a QQQ liquidity shock looks like, fast and self-correcting if liquidity does not break.

QQQ peak-to-trough drawdowns: -83% in the dot-com bust (2000-2002), -50% in 2008, -27% in 23 trading days during COVID 2020, and -33% in 2022. The 2020 crash was followed by a +47% Q2 rebound, the canonical fast V. The three QQQ drivers in any cycle are real rates (multiple), capex narratives (especially semis and AI), and the largest five names' earnings, because index concentration means the median stock matters less than the marginal mega-cap print.

First, NVDA datacenter revenue growth and capex guidance from Microsoft, Alphabet, Meta, and Amazon. The four hyperscalers have been spending roughly $300 billion combined annually on AI infrastructure; any deceleration shows up in QQQ before it shows up in SPY.

Second, the 10Y TIPS real yield. QQQ is more rate-sensitive than SPY because of duration. A 50bp move in real yields typically shows up as a 2-3% QQQ move in the opposite direction.

Third, the QQQ-SPY relative strength line. When QQQ leads, growth is winning the regime; when SPY leads, the rotation is underway. Inflection points historically front-run sector rotation by 2-4 weeks.
