In various discussions it is often claimed that YahooFinance always processes the splits into their historical data, but GoogleFinance does not. I have an example where GoogleFinance calculates a split into their historical data:

A 2:1 split happened on March 27, 2014. In the historic data this seems to be taken into account.

My question: Does anybody have example(s) where a company's split in the historic data of GoogleFinance is not taken into account (showing as a step in the time series)?

Actually there was no split in GOOG on 27 Mar 2014.

What happened is as follows: Google Inc (at the time, now called Alphabet) had class A shares trading as NASDAQ:GOOG. In early 2014 it announced it would be issuing Class C shares to Class A shareholders as a stock dividend. The ex-date for this corporate action was 3 Apr 2014. These new class C shares began trading on a "when issued" basis on Nasdaq under the symbol GOOCV on 27 Mar 2014. On 3 Apr 2014, GOOCV was "issued" and became GOOG (and still trades under that symbol). Simultaneously, class A GOOG shares had a symbol change to GOOGL.

Some providers have erroneously shown this stock dividend as a split. It's not - it's a stock dividend. In terms of its value to the original GOOG (now GOOGL) shareholders, GOOCV closed at $567 on 2 Apr 2014, so that is its "value" as far as a dividend/distribution is concerned.

Neither GOOG nor GOOGL have ever had a stock split.

Your screenshot reveals a further error in that the "new" GOOG never traded prior to 27 Mar 2014. That history belongs to the Class A shares (now GOOGL).

Here's an example of when Google Finance has erroneously missed a (reverse) split: China Precision Steel Inc - CPSL. This was a 12:1 reverse split on exdate 20120828.

Here's an example of when Google Finance has erroneously missed a (very large) stock dividend/spinoff: NYSE:GHC ex-date 20150701. GHC spun-off Cable One Inc.

(these errors exist in Google Finance as at 4 Jan 2018)


Well, it sure looked like a 'split' in my account. I paid over $1k per Class A share before the split and the value drop in half when the Class C shares were issued. Not sure how you can consider this to be a dividend. My shares were definitely split.

  • A stock dividend is when a company gives its shareholders more stock, instead of cash. This is different from a split for many reasons, including tax treatment, and in this case, because you didn't get more Class A shares [which you would have in a split], you got Class C shares.
