Hi All
Hoping I can get some help from the community here. Going to preface this with saying I am struggling to actually communicate what I am trying to accomplish. I just have the idea in my head.
File 1 has securities data at a point in time. In this case 1/1/1997. To the right of that data I have a formula (done in excel) where I am looking to get the next price at point in the future. I like to think of this as the horizontal file.

File 2 has the individual security data at those further points in the future. I like this think of this as the vertical file.

The end result would be to match Symbol and Date across all the dates on the horizontal file. Something that looks like this.

Thank you for taking the time to read and any help you can provide.
