They made 160% on Medallion (8 billion originally, meaning 13 billion appx). Although there are "fees", those are also paid out to the employees, so it's just the richer guys paying the poorer guys more, so the number quickly reverts to the mean.
Simons took home 2.5, leaving around 10 billion.
RenTec has 300 employees, and let's just say 700 employee emeritus. 10 billion/1000=10 million.
AVERAGE. From the lowest researcher or secretary to Henry Laufer, Simons's #2 (who took home 125 million).
As for the norm, of course it's not the norm. But I also saw on Wilmott that at DESCo, if after a few years as a quant, you're not raking in at LEAST mid-high six figures, something has gone "horribly wrong". Meaning that as you go down the list to slightly lesser respected companies, the comp drops off even more. However, we're talking at a respectable shop that an entry level quant makes as much as an actuary.
At the best of the best, the comparison becomes plain silly.
Also, if you value your sanity, the boredom at actuarial work will quickly deprive you of it.
