Important Stock Ratios

What is the definition of Is Primary Listing?
This indicates whether this instrument is primary listed on its stock exchange. There are many dual listed companies on exchanges around the world who have their primary listing elsewhere. The Value of "Is Primary Listing" is set to either 1 or 0 where 1 indicates a primary listing.
This can be a useful flag for identifying companies eligible for inclusion in tax efficient wrappers like ISAs and SIPPs.
To filter for primary listed stocks in the relevant exchange, set this value equal to 1, or to find stocks that are primary listed elsewhere set this equal to zero.

What is the definition of Mkt Cap ?m?
The Market Cap is a measure of a company's size - or specifically its total equity valuation. It is calculated by multiplying the current Share Price by the current number of Shares Outstanding. It is stated in Pounds Sterling.
Market Capitalisation only takes into account the value of the company's shares (equity), it ignores the amount of debt a company may have taken on and therefore isn't the best indicator of the company's size. The Enterprise Value adds the net debt to the Market Cap and is a better indicator of the minimum amount that an acquiring company may have to pay to buy the firm outright.
What is the definition of P/S?
A price-to-sales ratio, or a stock's market price per share divided by the revenue generated by sales of the company's products and services per share. Some argue that, since sales figures are less easy to manipulate than either earnings or book value, the price-to-sales ratio is a more reliable indicator of how the company is doing. However, this measure was misused during the dot com years to promote companies with no earnings or profits.
This ratio is calculated on a Trailing Twelve Months (TTM) basis.
Some argue that, since sales figures are less easy to manipulate than either earnings or book value, the price-to-sales ratio is a more reliable indicator of company value.
When EPS are negative or depressed temporarily the Price to Sales ratio can be a more useful indicator than the PE Ratio, and a low P/S can indicate a higher profit potential if the stock recovers. Some commentators have called it 'The King of the Value Factors' and look for P/S ratios of significantly less than 1.
It should be noted that the P/S ratio was abused during the dot com years to promote companies with no earnings or profits.
