Community
Insights: Calculation & Data Differences
On Reddit, users noted that Google Finance and Yahoo Finance use different formulas
for calculating returns—Google uses opening price at start and
closing price at end, while Yahoo relies on closing prices only, resulting in
different return percentages.(reddit.com)
Also, historical discussions mention that MSN and Google Finance may not adjust for dividends or stock
splits, unlike Yahoo Finance, which typically does—making Yahoo a
more reliable source for long-term data analysis.(elitetrader.com)
