Rebuilt every trading night.\n As of Nov 9, 2026 , $1,000 in SPY held $78.60 of Apple, $373 in its top ten, and $627 across 494 others.\n Money Basics \u00b7 Lesson 2 of 7 1 2 3 4 5 6 7 \n Pick an amount. See how SPY's top holdings turn that amount into dollars. Amount you put in $1,000 On $1,000: Apple $79, NVIDIA $66, Microsoft $62, All other positions $793. Hypothetical amount. SPY's weights as of Nov 9, 2026. \n The question\n \"Everyone says to look at ETFs. But what is an ETF, and what do I actually own when I have one?\"\n The idea\n An ETF (exchange-traded fund) is a basket of investments split into shares that trade on a stock exchange. The fund owns the basket. You own shares of the fund, so each share is a small slice of everything in the basket . The shares trade all day, at a price that moves with the basket.\n The ETF is only the wrapper. What is inside decides how it behaves. So the most useful habit is to open the basket and look.\n Worked example\n Let's open SPY, which first traded on Jan 29, 1993 . It follows the S&P 500 , a list of about 500 large US companies used to measure the US stock market. A list like this is an index . \"Follows\" means SPY holds the same companies in the same proportions as the list, which makes it an index fund .\n Step 1. What is in the basket? By State Street's holdings file for Nov 9, 2026 , SPY held 504 positions (holdings).\n Step 2. How big is each piece? Each holding has a weight : its share of the fund's money. The top three:\n Apple: 7.86% \n NVIDIA: 6.64% \n Microsoft: 6.22% \n Step 3. Turn weights into dollars. Say you put a hypothetical $1,000 into SPY. Multiply each weight by $1,000:\n Apple: $1,000 \u00d7 7.86% = $78.60 \n NVIDIA: $1,000 \u00d7 6.64% = $66.40 \n Microsoft: $1,000 \u00d7 6.22% = $62.20 \n Step 4. Look at the whole. The ten largest positions add up to 37.3% of the fund, so $373 of your $1,000 sits in them. The other $627 is spread across the remaining 494 positions plus a sliver of cash ( 0.12% ), and 487 of all 504 positions are each under 1%.\n Those ten positions are nine companies: Alphabet (Google's parent) has two kinds of shares, GOOGL at 2.60% and GOOG at 2.09% .\n Step 5. SPY closed at $749.92 on Nov 10, 2026 . One share buys a slice of all 504 positions at once.\n The common mistake\n \"An ETF is a type of investment, so ETFs are all roughly alike.\" The ETF is the container, not the contents. SPY and BIL are both ETFs from the same company, State Street. SPY holds 504 company stocks. BIL holds 17 Treasury bills ( lesson 1 ). One rises and falls with the stock market; the other barely moves. Judge a fund by its basket, never by the word \"ETF\".\n Check your understanding\n Pick an answer to see why. Two of three right passes the lesson.\n 1. When you own one share of an ETF, what do you own? A A share of the company that runs the fund B A small slice of everything the fund holds C One share of each company in the fund D A loan to the fund Answer: B. A small slice of everything the fund holds. the fund owns the basket and each share is a slice of it. Not C: one share of every company would cost far more than one ETF share; you get a fraction of each, in proportion to its weight. 2. In SPY, Amazon's weight was 4.02% on Nov 9, 2026 . How much of $2,000 in SPY sat in Amazon? A $4.02 B $40.20 C $80.40 D $402 Answer: C. $80.40 . $2,000 \u00d7 4.02% = $80.40 . Not B: $40.20 is the answer for $1,000, not $2,000. 3. Fund X holds 20 stocks, and its ten largest are 80% of the fund. Compared with SPY ( 504 positions, top ten 37.3% ), Fund X is: A More concentrated: more of your money rides on a few companies B Less concentrated C The same, because both are ETFs D Impossible to compare Answer: A. More concentrated: more of your money rides on a few companies. in Fund X, $800 of every $1,000 sits in ten stocks, against $373 in SPY. Not C: being an ETF says nothing about how spread out the basket is. \n Takeaways\n An ETF is a wrapper. Open it and look at the basket before anything else. \n Multiply a holding's weight by your amount to see your dollars in it. \n Check the top-ten share: the higher it is, the more a few holdings drive your result. \n Do it on ETFIQ\n See what's inside your fund Your fund \n Where to next\n Next lesson: Cash or invested: what each paid this year Previous lesson: Where your money goes: needs, wants and saving Money Basics: all lessons The explainer behind this lesson ETFIQ Academy How ETFIQ computes these numbers \n Cite this page.
