Liquidity is the ease with which some asset can be converted to cash (the most liquid asset). For example, an individual can usually sell some stock and convert it to cash with ease, so stocks are relatively liquid. However, to sell a house and convert it to cash is a lengthy and complicated process, so a house is relatively illiquid. 

Bid-Ask Spread — February 6, 2020

Bid-Ask Spread

The bid-ask spread is the difference between the price the buyer is willing to pay and the price the seller is willing to accept for some number of shares of a security. For example, if the average bid for stock $XYZ is $5.25, and the average ask is $5.75, then the spread is $5.75 – $5.25 = $0.50. Bid-ask spread is a strong indicator of market liquidity, such that a lower spread indicates higher liquidity.

Beta — January 2, 2020

Beta

Beta, β or the beta coefficient is one of “The Greeks”. It describes how much the movement of the market as a whole affects the movement of a given stock. For instance, a stock with a beta of 0.75 moves up or down 75 points for every 100 points that the market as a whole moves. A beta that is greater than one indicates a volatile stock. In some cases, beta can be negative (i.e. the price of the security increases when the rest of the market falls, or vice versa), but this is extremely rare.
