The S&P Tech sector is showing another shade of its glory days. For the first time since the tech bubble popped back in 2000, technology companies have reclaimed a hefty 20 percent weighting in the Standard & Poor's 500 index.

Although that's a far cry from the record 34 percent weighting at the pinnacle of the tech boom in March 2000, the 20 percent threshold is nothing to sneeze at.

Indeed, even the energy sector failed to hit that threshold when it hit its all-time high back in 2008, with a weighting of 16 percent.

According to S&P’s Howard Silverblatt, since the current sector classification was introduced by S&P in 1989, only the financial and tech sectors have ever reached a 20 percent index weighting.

Back when the S&P 500 hit its historic high in October 2007, financials made up 20 percent of the index – only to see its weighting more than halved to 8.88 percent by the time the market hit a 12-year low in March 2009.


The Tech sector’s rise to a 20 percent weighting has come at the expense of financials. Over the past 10 months, since the S&P 500’s current 52-week high on April 29, technology companies have added about 4 percent, while financials have lost over 1 percent.

It also helps that the five highest-weighted tech stocks are all up double-digits since the S&P 500’s 52-week high. Notably, those five names make up 10 percent of the S&P 500 (or half of the tech sector’s 20 percent weighting):

Additionally, the S&P 500 tech sector has been down just four times this year and is currently leading the gains in 2012, up 12 percent, followed by financials, up 11 percent.
