A slew of poor earnings results from the biggest tech names, with the latest lackluster results from Apple (NasdaqGS: AAPL), have dragged on the technology sector. However, an equal-weight tech-related exchange traded fund has been holding up surprisingly well.

Following Apple’s earnings miss after the close Wednesday, the Guggenheim S&P Equal Weight Technology ETF (NYSEArca: RYT) rose 0.1% on Thursday while the Technology Select Sector SPDR (NYSEArca: XLK) fell 0.9%.

Apple is exerting the biggest pressure on U.S. technology earnings, which is now the worst performing area of the S&P 500 this year, reports Richard Blackden for the Financial Times.

“Apple was a very large part of the S&P 500 growth during this cycle,” Jonathan Golub, chief market strategist at RBC Capital Markets, told the Financial Times. “It was a big growth engine and I don’t think it is coming back.”

According to FactSet, Apple could account for more than half of the 8.3% decline in technology earnings projected for the first quarter.

Other large tech names have also disappointed this earnings season, Google’s parent company Alphabet (NasdaqGS: GOOGL) has declined 7% since its weak earnings last week while streaming site Netflix (NasdaqGS: NFLX) decreased 15%.

These poor first quarter performances out of the large tech giants are weighting on market cap-weighted technology sector ETFs while the equal-weight tech ETF has held up. Over the past month, XLK dipped 0.9% and RYT rose 0.7%. In the past three months, RYT has increased 10.3% and XLK rose 7.8% [Read more: Alphabet, Microsoft Miss Reveals Pitfalls of Market-Cap ETFs].

XLK, a cap-weighted ETF, is top heavy, with a 14.0% position in AAPL, 9.8% Microsoft (NasdaqGS: MSFT), 6.0% Facebook (NasdaqGS: FB), 5.7% AT&T (NYSE: T), GOOG 5.1% and GOOGL 5.1%.

In contrast, RYT, an equally weighted ETF, more or less evenly spreads out its holdings, with the largest component Total System Services (NYSE: TSS) at 1.7% of its portfolio. Consequently, the fund takes a larger tilt toward smaller tech companies.

RYT’s market capitalization weights include mega-caps 14.5%, large-caps 39.8% and mid-caps 44.2%. In comparison, XLK has a hefty 68.0% tilt toward mega-caps, 23.0% large-caps and 8.9% mid-caps.
