re: Special Purpose Acquisition Company (SPAC) Discussion

A few questions on spacs. So far I have been playing the close to nav strategy. Just on a basic robin hood account. But I am interested in buying the units pre split (on fidelity). Basically when you buy a unit you get the common plus half a warrant when it splits right? I am assuming you cant use margin like on commons, so would this be a good play for a roth ira Thanks in advance.
