+The adjusted close

Adjusted Close provides the closing price for the requested day, week, or month, adjusted for all applicable splits and dividend distributions. Data is adjusted using appropriate split and dividend multipliers, adhering to Center for Research in Security Prices (CRSP) standards.

  • Split multipliers are determined by the split ratio.
    • For example, in a 2 for 1 split, the pre-split data is multiplied by 0.5.
  • Dividend multipliers are calculated based on dividend as a percentage of the price, primarily to avoid negative historical pricing.
    • For example, when a $0.08 cash dividend is distributed on Feb 19 (ex- date), and the Feb 18 closing price is $24.96, the pre-dividend data is multiplied by (1-0.08/24.96) = 0.9968.

Here's an example

Let's take a look at how split and dividend multipliers are calculated and applied to determine adjusted close prices. We'll start with this table of historical prices, a split, and a dividend:

Date Close, Dividend, or Split
2/13/03 Close = 46.99
2/14/03 Close = 48.30
2/18/03 Split = 2:1
2/18/03 Close = 24.96
2/19/03 Cash Dividend = 0.08 (ex-date)
2/19/03 Close = 24.53

The multipliers we'll use are determined from the split and dividend:

  • Split Multiplier = 0.5
  • Dividend Multiplier = 1 - (0.08/24.96) = 0.9968 

Using these split and dividend multipliers, the adjusted close prices are calculated for those dates prior to the split:

Date Adjusted close calculation
2/13/03 0.5 * 0.9968 * 46.99 = 23.42
2/14/03 0.5 * 0.9968 * 48.30 = 24.07
2/18/03 0.9968 * 24.96 = 24.88
2/19/03 24.53
