Change Relative Reference To Absolute

I have an Excel workbook with multiple worksheets. One of the worksheets has a live data feed for stock updates. I extract data from the live feed (it's in multiple sentences) and pull it into 6 columns. In another worksheet, I pull those 6 columns into the sheet through the use of Index / Match. That second sheet has additional formulas that essentially analyze the data. As the data refreshes, the existing data moves down the column.

What I didn't think about was the fact that at times, a stock may be listed several times because different brokers are offering updates. Because I used Index / Match, it will look for the first match from the top and display that data in the relevant columns. Unfortunately, some of the data needs to stay with the matching row (and stock ticker) but because of the way I wrote the formulas in Index / Match, it just finds the first matching target and displays that data.

I can correct this by using an absolute reference ($) but I can't find a way to "copy down" formulas using absolute references. I also have one column of cells that contain 1 absolute reference and one relative reference.

I'll re-write this manually if I have to but I have 1,800 cells to change.
