Answer:
an increase in the number of common shares outstanding
Step-by-step explanation:
A stock split is when a company increases the number of its shares outstanding.
for example if a company has 10 million shares outstanding at a price of $20, earning per share is $10 and dividend per share is $0.50. this company announces a 2 for 1 split :
the number of outstanding shares becomes 2 x 10 million = 20 million
stock price becomes = $40 / 2 =$20
earning per share = $10 / 2 = $5
dividend per share = $0.5 / 2 = $0.25
p/e before split = $40 / $10 = 4
P/E after split = $20 / $5 = 4
so stock per share, earning per share and dividend per share decreases. P / E remains unchanged
