All Historical Prices are Adjusted

At KlickAnalytics, we adjust our historical price data to remove gaps caused by stock splits and dividends.

For example, if a stock splits 2-for-1, the price is suddenly half of what it used to be, creating a large gap down on the chart. If you were unaware of the split, the chart would give you the impression that something bearish happened to the underlying company. In addition, most of the technical indicators on that chart would give sell signals because of the big drop in prices.

In order to prevent these kinds of misleading signals from appearing on our charts, we adjust all the historical data prior to the event. In the case of a 2-for-1 split, we divide all of the historical prices for the stock by 2, then multiply all of the historical volume by 2 so that the bars prior to the split match up smoothly with the bars that appear after the split. In addition to performing adjustments that remove large gaps caused by splits, we also adjust our historical data to remove smaller gaps caused by dividends. Dividends Adjustments Historical prices are adjusted by a factor that is calculated when the stock begins trading ex-dividend. The amount of the dividend is subtracted from the prior day’s price; that result is then divided by the prior day’s price. Historical prices are subsequently multiplied by this factor. Splits Adjustments Adjustments for stock splits are similar, but, to calculate the factor, we divide the number of shares after the split by the number of shares before the split. Just like with dividend adjustments, we also multiply all historical prices prior to the split by split factor.

Please note that;

  • Our adjusted historical price data cannot be used to determine the actual buy or sell price for a stock at some point in the past.

  • Our adjusted historical price data may not match up with unadjusted data from other sources.
