A very important aspect of MTG finance is have a good estimate for a given card's price floor and price ceiling. The basic economic principle here being the idea that you want to buy low and sell high. For Collected Company, the window to buy low has certainly passed.
The question is, how high do we expect Collected Company to go? It's currently $11+ in the set being drafted right now that is about to be drafted a bit less with Modern Masters 2015 coming out this week and Magic Origins on the horizon.
With the card seeing success in both Standard and Modern, the demand is certainly there. BBD was even crazy enough to play the card in Legacy. He split a Legacy IQ with the following list:
This build is wonky and unrefined, but that really helps to illustrate the card's power. Even without a good list, it fits the bill in this pile of mish-mashed good cards.
It's worth noting that the MTGO price of Collected Company is only about 6.5 tix, which is a little disconcerting when you factor in that Dragons of Tarkir is the one booster from Tarkir block worth more than 3 tix at this point in time. Alternatively, the spread for paper copies is a scant 22%. That is to say that you could literally buylist 81 copies to Card Kingdom for $9 each at the time of this writing.
As you can see, there are a lot of factors at play when trying to determine a card's ceiling. Ultimately, you have to take some risk in your decision to invest or avoid any given card, otherwise finance just wouldn't work.
