## Two Portfolios Combine
Remarried couples with two separate retirement accounts often find overlapping holdings in their portfolios.
## Three State Street ETFs
State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF covers US stocks, State Street SPDR Portfolio Developed World ex-US ETF covers developed markets abroad, and State Street SPDR Portfolio Aggregate Bond ETF covers bonds.
## Why Overlap Doubles Risk
Merging two diversified portfolios can concentrate risk on the same big companies, reducing overall diversification.
## SPTM Tracks US Stocks
SPTM covers US stocks with a 13.6 billion net asset value, including Apple at 6.1% of assets.
## SPDW Covers Developed Markets
SPDW includes Japan, Australia, the UK, continental Europe, Hong Kong, Israel, South Korea, and Singapore.
## SPAB Adds Bond Exposure
SPAB covers US debt with a 4.2% yield, but loses value as interest rates rise.
## Paperwork Before Merging
Update beneficiary designations and account titling to avoid tax issues and inheritance problems.
## Trade-Offs After Merging
SPTM focuses on big US companies, SPDW brings currency swings, and SPAB lags in strong markets.
## Key takeaway

Merging two retirement portfolios that overlap creates concentrated risk. Three State Street ETFs eliminate duplication.
