They’re not all created equal. The IBA one was a mortal fucking lock, I considered using the maximum leverage I had available to me (and probably should have done it). It was literally a bet against a natural disaster/act of God. In hindsight, bird flu ripping through their farms was for sure the vast majority of the risk there. Wish I’d bet more on that one.
ATVI was the riskiest, but I also feel like I ran pretty bad on that one and am still likely to prevail in the end. X was a good example of like a really good spot to get myself into, things falling apart on it, and still managing to get out without taking an L. And the downside risk there was pretty capped (20-25% drop).
ATVI was an exception, that was pure merger arb, but the other merger arb spots I’ve ended up in were because I bought the company as a value investment, understood the company reasonably well, and then when the merger happened I knew what a steal the buyers were getting.
