Investing in ETFs to Track the S&P 500 or the Nasdaq 100

Investing in ETFs becomes really popular in the last few years. But, do you know, what are you buying when you are investing in an S&P500 or Nasdaq 100 ETF?

If I want to put $10,000 into S&P 500, I will invest $365 in Apple (AAPL), $260 in Microsoft (MSFT), $190 in Amazon (AMZN), $177 in Facebook (FB), $170 in Johnson & Johnson (JNJ), $164 in ExxonMobil (XOM) and the rest of the sum into another 494 companies. So the S&P 500 index is not equally weighted. The weight of the six largest members are 13.26%.

If you are curious about the full list you can read here: S&P 500 Companies by Weight.

The Nasdaq 100 shows greater concentration than S&P 500, and the weight of the six largest members are 42.01%.

If I want to put $10,000 into it, I will invest $1,160in Apple (AAPL), $826 in Microsoft (MSFT), $727 in Amazon (AMZN), $561 in Facebook (FB) $927 in Alphabet (GOOG and GOOGL) and the rest of the sum into another 94 companies.
