Index maintenance[edit]
In order to keep the S&P 500 Index consistent over time, it is adjusted to c
apture corporate actions which affect market capitalization, such as additio
nal share issuance, dividends and restructuring events such as mergers or sp
in-offs. Additionally, to remain indicative of the U.S. stock market, the co
nstituent stocks are changed from time to time.[3]
To prevent the value of the Index from changing merely as a result of corpor
ate financial actions, all such actions affecting the market value of the In
dex require a divisor adjustment. Also, when a company is dropped and replac
ed by another with a different market capitalization, the divisor needs to b
e adjusted in such a way that the value of the S&P 500 Index remains constan
t. All divisor adjustments are made after the close of trading and after the
calculation of the closing value of the S&P 500 Index. There is a large ran
ge of different corporate actions that can require the divisor to be adjuste
d. These are listed in the table below:[18]
Type of Action Divisor Adjustment
Stock split (e.g. 2×1) No
Share issuance Yes
Share repurchase Yes
Special cash dividend Yes
Company change Yes

Rights offering Yes
Spinoffs Yes
Mergers Yes

fund或index fund要买卖大量的股票都要经过大银行。 | r*****e
