Is there anyway to calculate total return for a stock between two time periods? I am new to Quantopian and trying to test a dual momentum theory that looks at total return. But, it looks like the only way to get total return on Quantopian is to hold the stock for the given time period. But, what I want is to do is use total return over the previous year as a signal for which stocks to buy. (Basically, test dual momentum strategy)
