Marshall: Marshall Wace limits strategy capacity to force capital diversification
“So we've always worked on the basis, first of all, that we were size constrained in everything we did, and that led us to allow different strategies to develop their life and to distribute the capital as much as possible, really.”

“We have 1000, well, historically, upwards of 3000 people who have contributed to TOPS and been measured. For long periods. Three, five, 10, 20 years in some cases.”
Success ratios between 50% and 60% prove skill is statistically persistent
“If you begin to see that the individual not only Consistently delivers alpha, but their success ratio is consistently between 50 and 60%, so they're consistently getting it more right than wrong. There's a skew in there, and then you can look at how that works…”
Marshall: Marshall Wace optimizes portfolio construction and capital allocation to alpha, not returns
“The thing you're optimizing is not a return objective. It's an alpha objective. So it's the performance of those ideas against whatever the benchmark is. And you create information ratios and risk manage around the alpha. And for our managers, it's actually th…”

Paul Marshall: Crowded Shorts Signal Quality but Spike Squeeze Risk
“The irony, of course, is that a crowdedness of a short Is a sign that it's a good short. Ah, it's going to go down, because smart money thinks you should be short. But, crowdedness of a short causes it to be much more volatile in the market. And when you get t…”
Marshall Wace Uses Z-Scores to Quantify and Manage Short Crowding
“We have rules about individual stocks, both on the long and the short side, in terms of how big we can be in the positions. But we also implement it at the aggregate level. So we have a crowdedness factor. So we have a Z-score approach to measuring short crowd…”
