# Formula for “Return” in FinancialData

After I get the data for the return, divident, and price of a stock with e.g.

FinancialData["BMY", "Return"] which gave -0.0153019
FinancialData["BMY", "Dividend"] which gave 0.41
FinancialData["BMY", "Close"] which gave 48.16


This stock lost \$0.76.

What is the exact formula used by Mathematica that relates this daily return to the closing price, dividend, and loss/gain?
