How to forecast AAPL with auto arima in RStudio and predict future trends

[@kurzashane]

Would it be possible to alter the forecast component to look at an individuals portfolio of multiple stocks and their value to forecast the total value of that portfolio?

[@techknowhow4802]

That would take a little more than just altering the forecast function. You would have to figure out not just what stocks and the related info, but you would also have to bring them together and then weight each stock as part of the whole nd do this each day the stock market traded or was open. Good question. Maybe we will do this in a future video? How many of my wonderful subscribers would like to see this?

Can you explain the ARIMA(1,1,28) I understand the 28 but how do you know what to put for the first 2? How are you deciding if it should be (1,2,28) or (1,1,28) and so on?

[@techknowhow4802]

Look at the other ARIMA videos on my channel. Some go far more in depth. Some are meant to be more of a quick walkthrough. ☺

In auto.arima(AAPL_Close_Prices, Seasonal= FALSE) , why is seasonal = False?

[@techknowhow4802]

Seasonal = T or True allows the ARIMA model to search for seasonal models. Seasonal= F or FALSE prevents this. Sometimes this has an impact on the data. Sometimes it does not. It all depends upon the data. In this case we went without seasonal modeling - this was meant to be a quick and easy way to forecast virtually any stock or ETF. There are other videos on my channel that go way more in depth into ARIMA models, forecasting, and more. :)

Thank you. I like forecasts like this - they are fun and easy to do. I am glad you liked it. I may do another stock forecast shortly. What stock would you like to see a forecast on?

Have you ever considered to release a kind of guide book for beginners to learn? I would definately buy it, or would appreciate as well a recommendation on the various literature about this theme. Great content!

[@techknowhow4802]

Maybe one day! Right now, when I have extra time I have a long list of data science tutorials I want to create and publish. Thank you for the wonderful comment. :)

I can get getSymbols even I have installed all the packages

[@techknowhow4802]

Look into upgrading your version of R and Rstudio - those are the usual culprits. Many libraries when they are updated are not tested against older versions.
