Further to the previous posts, explaining the display of these import fundamental indicators. A discussion of the values used is required. It should be noted that the most recent values are used. Even for what appears to be historical data.
A page showing the trading activity for a trading day, has its PE value (Price to Earnings ratio) calculated using the most recent EPS value (Earnings per Share). At first glance this may appear to be incorrect.
But remember that the earnings/share value is usually historic, where as doing it this way, as well as being easier provides an insight as the future trade is leading into, and as such, it shows a more meaningful figure than an old out-of-date value.
The earnings figure is of course only update with the companies disclosed results, and is never a real time value.
Values by date can still be seen on the company's home pages, if you wish to see how this value has recently changed.
