Key Concepts Across All Markets
With all four market types covered, let's bring it together with the foundational concepts that apply across every market: liquidity, price discovery, and the two pricing mechanisms.
Liquidity
- Liquidity is how easily a security can be bought or sold without significantly affecting its price
- The secondary market is the primary source of liquidity for investors
- More active trading = more liquidity = tighter bid-ask spreads
- Exchange-listed securities are generally more liquid than OTC securities because more buyers and sellers participate
Why liquidity matters:
- Without liquidity, investors could not exit positions when they need to
- Liquid markets attract more participants, which further increases liquidity (a virtuous cycle)
- Illiquid securities carry higher risk because they may be difficult to sell at a fair price
Exam Tip: Gotchas
- Liquidity comes from the secondary market, not the primary market. The primary market is where securities are first issued; the secondary market is where ongoing trading provides liquidity.
Price Discovery
- Price discovery is the process by which market trading determines the fair value of a security
- Every executed trade provides a data point about what buyers and sellers collectively agree a security is worth
- More transparent markets (exchanges) produce more efficient price discovery than less transparent markets (OTC)
Auction Market vs. Negotiated Market
These are the two fundamental pricing mechanisms in securities markets:
| Feature | Auction Market | Negotiated Market |
|---|---|---|
| How prices are set | Competitive bidding matches buyers and sellers | Dealers quote bid/ask prices; prices are negotiated |
| Key participant | Designated Market Maker (DMM) maintains order | Multiple market makers compete for trades |
| Transparency | All orders visible; prices exposed to the market | Less transparent; prices determined through dealer quotes |
| Example | NYSE | OTC markets, Nasdaq (dealer-market roots) |
- In an auction market, buy and sell orders are submitted and trades execute when prices match: the highest bid meets the lowest ask
- In a negotiated market, dealers act as intermediaries, quoting prices at which they are willing to buy (bid) and sell (ask). Prices are negotiated between parties rather than matched through open competition
Memory Aid: Exchange = Listed = Auction; OTC = Unlisted = Negotiated
Exam Tip: Gotchas
- Auction market = competitive bidding (NYSE). Negotiated market = dealer quotes (OTC/Nasdaq). The SIE may describe a pricing mechanism and ask you to identify which market type it belongs to.
Market Makers
- Market makers provide liquidity by maintaining a continuous two-sided market, always quoting both a bid price (what they will buy at) and an ask price (what they will sell at)
- The difference between bid and ask is the spread, which is how market makers earn profit
- On the NYSE, the primary market maker is the Designated Market Maker (DMM), who has obligations to maintain fair and orderly markets for assigned securities
- On Nasdaq and OTC markets, multiple market makers may compete for the same security, which can narrow the spread and benefit investors
Think of it this way: A market maker is like a car dealer who always has a "buying price" and a "selling price" posted. The gap between them (the spread) is how they make money, and their constant willingness to trade keeps the market moving.
Exam Tip: Gotchas
- Nasdaq is now a registered national securities exchange, but it originated as an OTC/dealer market. The SIE may test whether you know Nasdaq's historical classification versus its current status.
- Market makers provide liquidity by always quoting both a bid and an ask. This is what "two-sided market" means.
- Securities prices are set by market trading, not by any regulator or issuer.
