A daily roundup of new ETF listings from around the world.

American insurance giant Transamerica has listed four new multi-asset ETFs in the US. The products are named "DeltaShares", which is a trademark of Transamerica. They are:

• DeltaShares S&P 500 Managed Risk ETF (DMRL) • DeltaShares S&P MidCap 400 Managed Risk ETF (DMRM) • DeltaShares S&P SmallCap 600 Managed Risk ETF (DMRS) • DeltaShares S&P International Managed Risk ETF (DMRI)

DMRL, DMRM and DMRS track well-known American indexes while DMRI will track the lesser-known S&P EPAC Ex-Korea LargeMidCap Index.

The reason the ETFs are branded "Managed Risk" is that they have a maximum volatility level to act as a warning siren and two fixed-income subindexes to act as pressure valves. If the maximum volatility level is exceeded, the benchmark index rebalances and puts more weight on its fixed-income subindexes.

There is no restriction on how much or how little each index can be weighted. If volatility in the benchmark index is low, each fixed-income subindex can in theory be weighted at 0%. If volatility is high a fixed-income subindex can, in theory, be weighted 100%.
