Method · Comparison

The key is that 'even indexes that look similar can diverge because of subtle differences in construction.' Both are highly concentrated in tech, so both had larger gains in up-markets but share a tendency toward deeper drawdowns than broadly diversified indexes in declines. In the comparison calculator, review each index's ending balance together with its maximum drawdown and recovery period. The point here is less 'which is superior' and more to understand that seemingly similar products can differ in risk and return when their holdings and weighting rules differ.

Why this period and asset

The Nasdaq 100 (QQQ) and the technology sector (XLK) look similar with their heavy tech weighting, but they are built differently. The Nasdaq 100 holds 100 large Nasdaq-listed companies, so beyond tech it includes some non-tech firms in consumer and healthcare. XLK holds only companies classified in the S&P 500's 'information technology' sector, giving it an even higher pure-tech weight. Over the past 15 years, Big Tech leadership lifted both indexes strongly, but performance diverged subtly depending on which companies land in which index and how heavily individual megacaps are weighted. If a particular megacap is weighted more in one index, its swings can translate into a performance gap.

Caveats & limits

This comparison reflects one specific past period, and which one leads can change with the start or end date. Both are concentrated in tech, so both can have higher volatility and drawdowns than broadly diversified indexes, and past performance does not guarantee the future. In real investing, fees, taxes, and exchange rates (for dollar-denominated assets) affect outcomes. This page recommends no purchase; it is educational material comparing character.
