Understanding Bid Size: Your Gateway to Informed Trading

Gain a deeper insight into bid size, a crucial measure of liquidity and demand for securities in financial markets.

Unpacking the Bid Size in Trading

The bid size represents the quantity of a security investors are willing to purchase at a specified bid price. For those viewing level 1 quotes on their trading screens, the bid size reflects the amount of shares investors intend to purchase at the best available bid price.

Key Insights

  • Bid size quantifies the amount of a security that investors are willing to acquire at a specified bid price.
  • It is usually stated in board lots representing 100 shares each. A bid size of four, for instance, signifies 400 shares.
  • The bid size is crucial as it indicates the demand and liquidity of a security.
  • Level 1 quotes display the bid size only for the best available bid price.
  • Level 2 quotes offer depth of market information across several layers of bid prices and bid sizes.

How Bid Size Operates

Bid sizes are generally shown in board lots representing 100 shares. As an example, a level 1 quote with a bid price of $50 and a bid size of five implies that the best available offer is $50 per share for 500 shares. A stockholder could consequently sell up to 500 shares at $50 each.

Bid size is contrary to ask size, where ask size denotes the quantity of security investors are offering to sell at the specified ask price. Market participants often compare differences between bid size and ask size to gauge the supply-demand dynamics of a security.

Beyond the best available bid price, there are usually multiple bid prices at inferior (lower) prices, each paired with their respective bid size. This extensive detail is accessible via level 2 market quotations.

Real-World Application of Bid Size

Consider another example: Assume there is a bid size of 10 (1,000 shares) at a bid price of $49. An investor aspiring to liquidate 1,500 shares would achieve a total of $74,000 ($25,000 from the first 500 shares at $50 each, and another $49,000 for the remaining 1,000 shares at $49 each).

To delve deeper, level 2 quotes are necessary as they reflect bid prices and sizes below the highest available bid. This intel often exists as a premium feature in brokerage accounts.

The depth of market (DOM) data offers a glimpse into the liquidity architecture surrounding a security. Using our example, post selling 1,500 shares, the next superior bid price might drop substantially, perhaps to $40.

Here, an investor deciding to offload significantly more than 1,500 shares might trigger a steep market price decline. Hence, the strategic move could be to delay selling further to negotiate a finer price and circumvent devaluing their remaining holdings.
