Emerging markets debt specialist Santamaria had been with AB since June 2010 and is understood to have stepped down in January and resurfaced at BlueCrest earlier this month.
This brings to an end nearly seven years with AB, where Santamaria had been a named manager across the AB FCP-I Emerging Markets Debt Portfolio, as well as working on three emerging market multi-asset funds.
The largest of his four funds was the EMD fund, which has $1 billion in assets, and is co-run by bond veteran Paul DeNoon, EMD specialist Shamaila Khan and fund manager Christian DiClementi. It is understood this trio will retain their roles with no additional managers being added.
In his new capacity, Santamaria has been named as a portfolio manager covering emerging markets at hedge fund group BlueCrest.
He takes with him 28 years of investment experience, having previously worked for AIG, Lehman Brothers and Global Securities Advisors.
BlueCrest Capital Management was founded in 2000 with a focus on fixed income investing and has developed into one of the world’s largest global alternative asset managers.
On a three-year total return basis, the AB FCP I-Emerging Markets Debt fund returned 14.6% in US dollars to the end of February 2017. This compares to a 19.2% rise by its Citywire-assigned benchmark, the JP Morgan EMBI Global, over the same period.
