See the 3 stocks that displayed the biggest bids and offers last week

The top stock has a best depth value of $8m.

Best depth value is one way to measure a stock’s tradability. It represents the amount of potential trade size on the best prevailing bid and best prevailing offer price, averaged throughout the entire trading session.

As defined by SGX, rather than expressed in terms of the number of board lots – best depth value is expressed in terms of the dollar value of those board lots. The best depth value combines both the dollar size of the prevailing bid and the prevailing offer.

SGX reveals that the three stocks that displayed the biggest bids and offers in terms of dollar amounts last week from 1 to 5 December were Singapore Telecommunications, Wilmar International and Keppel Corp.

The average best depth value of Singapore Telecommunications for last week was S$8,070,489.66. Singapore Telecommunications had an average of best bid value of S$4,249,286.19 and an average of best ask value of S$3,821,203.48.

Assuming a trading price of S$3.90, the best depth value implied that, on average, as many as 1,089 board lots in the stock (or 1,089,560 shares) could have been readily sold at the prevailing bid and 979 boards lots in the stock (or 979,795 shares) could have been readily bought at the prevailing offer, over the timeframe.
