Nasdaq Composite

© StocksToTrade.com 2021
What It Is
Since 1971, the Nasdaq Composite index has tracked almost all of the stocks listed on the Nasdaq stock exchange. These stocks are geared heavily toward the information technology sector, i.e., tech stocks.
How It Works
The Nasdaq Composite is capitalization weighted. In plain English, that means that the companies with the highest market caps have the most influence over the index value. The index’s daily price is a calculation of average opening and closing prices for nearly all the stocks trading on the Nasdaq exchange.
Why It Matters
Today, tech companies dominate the U.S. economy. Even companies that aren’t pure tech by definition are likely doing business with one in some way.
Since the dot-com boom, the Nasdaq Composite’s profile has risen considerably as tech stocks consistently outperform the broader market.
Standard & Poor’s 500
What It Is
Meet the Standard & Poor’s 500 — aka the S&P 500 or S&P. This index includes 500 of the most powerful companies listed on U.S. exchanges. It’s BIG. Think of it as the ultimate benchmark of major U.S. equities.
The S&P 500 is often considered the most representative of the major indexes. That’s because it includes a broad range of companies from diverse sectors.
How It Works
A committee selects the stocks that make up the S&P 500. Like the Nasdaq Composite index, the S&P 500 is capitalization weighted.
Today, because mega-cap tech companies’ valuations have ballooned into the trillions, the top 10 stocks in the S&P 500 make up over 26% of its entire value … That’s unprecedented.
Why It Matters
We can’t overstate the importance of the S&P 500. There are roughly $4.6 trillion in global assets tied to its performance. Pension funds, retirement accounts, and mutual funds all use the S&P 500 as a primary investment tool. That’s been the case for decades now.
In the past, when the S&P 500 lost considerable value, like during infamous stock market crashes, millions of investors around the world felt the effects. The financial damage has been in the trillions.
But the reverse is also true. Had you invested $10,000 into the S&P 500 each year since 1990 — and done nothing else — you’d have approximately $1.1 million today.
Dow Jones Industrial Average
What It Is
The Dow Jones Industrial Average is most commonly referred to as the Dow Jones or the Dow. It’s a price-weighted index of 30 blue-chip companies listed on U.S. stock exchanges. These are the so-called big boys like Boeing, Coca-Cola, McDonald’s, and Visa.
You won’t find unprofitable tech startups in the Dow … That’s why many traders and portfolio managers view it as a more reliable benchmark.
How It Works
It’s up to a committee to select the 30 stocks that make up the Dow. Then the committee weighs the stocks according to share price (as opposed to their market cap). In other words, a stock that trades for $500 will have a higher influence on the Dow’s value than a stock that trades for $50.
This practice is somewhat controversial. It can cause stock splits to harm a company’s weighting. That wouldn’t happen in a cap-weighted index.
Why It Matters
The Dow Jones is in its 13th decade of existence, and history plays a role in the index’s continued benchmark legacy. The Dow is legendary to a LOT of investors and traders.
But these days, most portfolio managers would tell you that alternate indexes provide a more accurate representation of the U.S. economy.
Bitcoin
What It Is
Cryptocurrencies are digital assets that are traded peer to peer. It’s generally unregulated by banks or exchanges. Bitcoin is the largest cryptocurrency by market capitalization. It was created in 2009 by an anonymous person presumably named Satoshi Nakamoto. It’s now the default benchmark for the broader cryptocurrency market.
How It Works
Unlike exchanges, which consist of hundreds (if not thousands) of real-world corporations, bitcoin refers to a single digital asset. The price swings can be wildly volatile and unattached to traditional metrics such as market cap, earnings per share, or revenue growth.
Why It Matters
Crypto is often criticized by legacy hedge fund managers and old-school traders … But it had a renaissance in the lockdown era. It went parabolic and gained support from institutional investors.
And, frankly, at a $640 billion market cap, bitcoin is too big to ignore.
10-Year Treasury Note
What It Is
The 10-year Treasury note is a debt obligation issued by the U.S. government. It’s a widely used benchmark for the performance of the broader U.S. bond market. Its performance is also sometimes thought to reflect the global equity market’s longer-term macroeconomic viewpoint.
How It Works
Investment banks go to a government auction to bid on bonds issued by the U.S. treasury. Then they sell them to their customers.
For normal T-notes, the interest rate is fixed at the auction — and interest is collected every six months until the note reaches maturity.
T-notes are typically seen as a low-risk investment because you’re guaranteed a certain yield when you buy it. But you also have no opportunity to earn more.
Why It Matters
The performance of the 10-year is seen as a benchmark for the overall bond market. The price fluctuations are also monitored closely during quantitative easing and rampant government spending.
