Nasdaq 100 vs S&P 500: the difference explained

Nasdaq-100 or S&P 500: the short answer

The S&P 500 holds about 500 large US companies from every sector, including banks. The Nasdaq-100 holds the 100 largest non-financial companies listed on Nasdaq, so it leans heavily on technology.

More tech means bigger swings: the Nasdaq-100 usually rises more in rallies and falls more in sell-offs. The two still move closely together, because the largest tech firms are big weights in both.

Nasdaq 100 vs S&P 500: when to pick which

If your view is on the US market as a whole, the S&P 500 is the usual benchmark, but BRVX does not offer it. If your view is on tech and growth, the Nasdaq-100 is closer, and BRVX offers it as XYZ100/USDT.

Index perps on BRVX settle funding every 3 hours, not every hour as on stocks.

What the Nasdaq-100 and S&P 500 track and how they are built

Both are stock indices: a single number that follows a basket of companies. Both are weighted by market value, so a large company moves the index more than a small one. The difference lies in which companies each index lets in.

The S&P 500 began in its 500-stock form in 1957. A committee picks members from US companies listed on the major US exchanges. Size, trading activity and a record of profits are part of the rules, so a young company that loses money usually stays outside.

The Nasdaq-100 began in 1985. It takes the largest non-financial companies listed on Nasdaq, chosen mainly by size, with no profit test. Some non-US companies qualify if their shares are listed on Nasdaq. The member list is reviewed once a year, in December. Weight limits stop the largest stocks from taking too big a share of the index.

What moves the Nasdaq-100 vs the S&P 500

Both indices react to the same big forces: the US economy, company earnings and interest rates. The difference is how strongly each one reacts, and to which news.

The Nasdaq-100 is more sensitive to interest rates. Growth companies are valued on profits expected years from now. When rates rise, those future profits are worth less today, so tech-heavy indices tend to fall harder. When markets expect rates to drop, the opposite often happens.

• Mostly Nasdaq-100: results and forecasts from the largest tech companies, AI spending plans, chip export rules, and demand for software and cloud services.
• Mostly S&P 500: bank earnings, oil and gas prices through energy stocks, health care, industrials and consumer staples.
• Both: US inflation and jobs data, central bank decisions, and the general mood of the market.

Nasdaq vs S&P 500 on the same day: a worked example

Because the biggest tech firms sit in both indices, the two usually move in the same direction. The size of the move is where they part. Here is an example with round, made-up numbers.

Say a large chipmaker cuts its sales forecast and rate worries grow in the same week. Tech stocks fall 4%, while banks and energy stay flat. If, in this example, tech is half of the Nasdaq-100 and a third of the S&P 500, the Nasdaq-100 drops about 2% and the S&P 500 about 1.3%.

Now reverse it. Oil jumps and bank shares rally while tech is quiet. The S&P 500 can rise while the Nasdaq-100 barely moves. So a trader with a view on energy or banks gets little of that view through the Nasdaq-100.

Nasdaq-100 vs S&P 500 trading hours and holding costs

The cash indices are calculated during the US stock session, 9:30 to 16:00 Eastern Time, Monday to Friday. News that arrives at night or on a weekend reaches the cash index only at the next open.

On BRVX, the Nasdaq-100 tracker XYZ100 is quoted around the clock, including weekends. The underlying exchange keeps its own hours, so a weekend price on BRVX is not an official index reading.

Holding a perp also costs money over time. On XYZ100/USDT, funding is charged every 3 hours, which means 8 periods a day, at 0.0068% per 3h. Long and short both pay it. The fee is 0.05% to open and again to close. As an example, a position kept for one week pays funding 56 times plus two fees, so check the live numbers before planning a long hold.

Common mistakes when comparing Nasdaq and S&P 500

Most errors come from treating the two indices as more different, or more alike, than they really are.

• Mixing up the Nasdaq-100 with the Nasdaq Composite. The Composite holds thousands of Nasdaq listings, financials included; the Nasdaq-100 holds only 100.
• Thinking one protects against the other. The same large tech companies lead both, so in a sharp sell-off they tend to fall together.
• Using the same leverage on both. A more volatile index needs a smaller position for the same risk, so check the current volatility of 15.7% before sizing.
• Forgetting holding costs. Funding every 3 hours adds up over weeks.
• Expecting dividends. A perp gives price exposure only, so no dividends are paid to the trader.
• Planning an S&P 500 hedge on BRVX. It is not listed there, so there is no second leg for that pair trade.
