Google Sheets Expert

I'm looking for someone to help me write a couple formulas.

For the sheet below:
https://docs.google.com/spreadsheets/d/1px03UiFEcTUWQ5JEqDZT31fFUyFpuAWkAGKtJQwwdoo/edit?usp=sharing

I'm hoping someone can help me integrate the following equations into column P:

Calculate a momentum score for each of the 16 ETFs. The authors of the strategy use a “13612W” score – a bit of a mouthful, but here’s how you work it out:

13612W = (12 (p0 / p1 – 1)) + (4 (p0 / p3 – 1)) + (2 * (p0 / p6 – 1)) + (p0 / p12 – 1)

Where p0 = the ETF’s price today, p1 = the ETF’s price one month ago, p3 = the ETF’s price three months ago, and so on.

The first term – (p0 / p1 – 1) – is the ETF’s percentage price change over the past month, and the second term – (p0 / p3 – 1) – is the ETF’s percentage price change over the past three months. You get the idea. Also, notice how the 13612W score overweights the most recent returns: the ETF’s one-month performance is multiplied by 12, its three-month performance is multiplied by a third of that (four), and so on. This gives more recent returns a greater impact on the strategy than older ones.



And for the second sheet I need to query the email addresses in 1 tab
And then populate those emails into another tab where the names on tab 2 and tab 1 match
Else return blank cell
