# Would I use rations, or something else to solve this?

#### oweaponx

Greetings, all. I’m not exactly sure how to word this, so hopefully this makes sense. I’m trying to figure out how to set this up, maybe a ration? P&L?

Let’s say I’m looking at a REIT, or maybe a fund. However, instead of buying the full amount of the item, I’m looking at a part.

To start, let’s say, to try and keep the numbers easy, that the item starts at $7,000. Later, it rises to$7,500. Still later, it drops to $7,250. Now, let’s say I’m using$20, as my start. How do I know what my equivalent will be, at $7,500. Then, as it drops, what will my equivalent be, when I want to sell. I’m also looking to do similar, with a start of$50, and \$100, as examples.

I hope this has made sense, and I appreciate help!
