As an occasional hiring manager in this space I can tell you that being tracked down and subjected to a personal sales pitch out of the blue is highly unlikely to make me look more favorably at you as a candidate than if you had merely submitted an application through the channels created for this purpose. If you have a genuine relationship with somebody that I know and trust and you can make that person put in a good word for you, that is different. Alternatively, if you happen to have done interesting research in a relevant area and send me an email with a copy of the paper along with a suggestion that you are available for an interview, that is also not a bad idea. But merely being able to figure out who the hiring manager is and cold calling him (or her) is not going to improve your chances for landing a quant job. A sales job may be a very different story....
