P/E

The share price divided by the company earnings per share for the last 12 months (EPS). It shows how many years the company would need to earn its current profit to «pay back» the price: a lower P/E means the stock is cheaper relative to earnings. The line has its own scale on the left.

For some companies earnings come from their quarterly reports: on the day of a new report P/E jumps (a purple tick at the bottom of the chart), between reports it changes only with the price. For others P/E uses current earnings, so before the latest report it is approximate. If earnings are negative, P/E is not shown.

From each purchase date there is a dashed line at the purchase price, and between it and each day close price — an area: green if the position is in profit, red if at a loss.
