Adobe Inc. is a multinational US computer software company, listed on the Nasdaq stock exchange (it is also a component of the Standard and Poor's 500 index). The following R output was obtained using weekly data for the period 27 February 2017 to 17 February 2020. In the estimation output 'log' is the natural logarithm, and 'd' is the first-difference operator. ADBE is the Adobe stock price, d(log(ADBE)) is the weekly log return on Adobe stock, and d(log(SP500)) is the weekly log return on the Standard and Poor's 500 index.
