⚙️ How the Nasdaq Works
The Nasdaq operates differently from older exchanges like the NYSE — and that’s part of why it became the world’s top destination for tech stocks.
🔑 Key Features You Should Know
1️⃣ Fully Electronic Exchange
Since its launch in 1971, Nasdaq has been the first stock exchange to run entirely on computers. There’s no trading floor, all trades happen digitally, using advanced algorithms that match buy and sell orders in real time.
2️⃣ Market Maker System
Instead of human floor brokers, Nasdaq relies on “market makers” — firms that continuously provide buy and sell quotes, keeping the market liquid and efficient. This system ensures you can trade even fast-moving stocks like Nvidia or Tesla without delays.
3️⃣ Listing Requirements
To be listed on the Nasdaq, companies must meet strict financial, governance, and reporting standards. This helps maintain trust, especially in high-growth sectors like biotech, cloud computing, and AI.
4️⃣ Opening and Closing Crosses
At the start and end of each trading day, Nasdaq uses special auction-like processes, called the Opening Cross and Closing Cross — to determine the official prices for stocks, balancing supply and demand.
🔍 Real-World Example
Let’s say you want to buy Amazon (AMZN) stock:
✅ Your online broker sends the order directly to Nasdaq
✅ Nasdaq’s electronic system finds a matching seller within milliseconds
✅ The trade is executed, and you officially own Amazon shares
This digital-first system is what makes Nasdaq faster, more scalable, and often more appealing for tech companies compared to traditional exchanges.
