Example
Suppose there is XY company,

Last trade = 23.45 USD

Trade time = 12.22 AM ET
Change = 
Prev close = 23.02 USD
Open = 23.05
 Bid   =  23.45 X 7000
Ask =
1y target Est. = 36.16 USD

Day's range =23.04 - 23.67
52wk range = 22.87 - 35.50
volume = 13,340,445
Avg volume(3m) - 66,197,500
Market cap = 223.01B
P/E (ttm) =
EPS(ttm) = 1.72
Div and yield =

So some points are missing. We have to calculate these.

What is change?
change = difference is last traded price and prev day closing price. So change = .43 USD positive.

What is P/E ratio?
We know that P/E ratio = current share price / EPS = 23.45 / 1.72 = 13.63

What is dividend yield assuming that company's forward dividend rate is .44 per share ?
Dividend yield = dividend per share / current stock price
                      = .44/23.45 = 4.26%
