At the end of second quarter, tech sector accounted for about 62% of the NASDAQ-100. If we add Telecommunications the weightage increases further to 66%. In the S&P 500, tech’s weightage is 28%. Even with the addition of Telecom the total comes to just 37%. Thus the high allocation of tech in the NASDAQ index is helping fuel the huge rally.

Financials account for over 12% of the S&P 500 while it has no allocation in the NASDAQ-100. The crash in bank stocks this year has adversely impacted the S&P 500 while NASDAQ-100 remains unscathed.

Consumer Discretionary has a high allocation in the NASDAQ-100 at 20%. If the US economy goes into a recession this sector is bound to get crushed. In the S&P 500 it accounts for about 10%.

Overall though NASDAQ-100 is soaring this year relative to the S&P 500, risk remains high for NASDAQ stocks. So investors need to take that into consideration when making investment decisions.
