Declawed, defanged and neutered: how do I get promoted?

Hi Monkeys,

Reaching out to this community because I am in a bit of a pickle and could really use some non sugar-coated advice.

I have been at my mid-market shop for a bit over a year, after making a lateral move from a similar firm due to my unwillingness to deal with internal politics and god awful lifestyle. This decision might be biting me in the rear end right now. 

The new shop is much better in terms of lifestyle, the flip side though is that it struggles with deal flow and my previously 'hot' profile is becoming a bit stale. In over a year here I haven't seen a deal close. The associate to analyst ratio is 3:1, and I am stuck on low-value tasks, which nobody else is doing (the "this needs to happen and someone needs to do it" kind). While the desk research I do could result in some deal flow, the senior team isn't easily available to give input/ greenlight outreach. My work just dies or goes on the backburner, while other tasks, admin and inbound take priority, because, you guessed it, "this needs to happen and someone needs to do it".

Recently I started being a bit more proactive, voluntarily taking on more responsibility, and churning out a lot of output in terms of volume (markedly more than my comparable peers here), but I'm afraid that without tangible deal flow this is meaningless. I am also not convinced that the partners know just how much I plow through, with barely any supervision. On the "invisible" work I am fully on my own, while on the work that gets exposure in team meetings there is an often hands-off senior attached. I don't want to end up being the hardest working loser in the galaxy.

I feel declawed, defanged and neutered as a junior, and am frankly getting impatient. With less than 5 months left before the promotion discussions, I am not sure it will even be considered. 

And here is the question, my dear experienced Monkeys: what would you do to try and squeeze a promotion into this season still? Should I jump ship? What do you look at to decide if an Analyst can become an Associate?
