Why Mid Cap Blend
Mid cap companies, with market capitalization in the range of $2 billion and $10 billion, offer investors many things that small and large companies don’t, including less risk and higher growth opportunities. Thus they have a nice balance of growth potential and stability.
Blend ETFs usually hold a mix of growth and value stocks as well as stocks that exhibit both value and growth characteristics.

It has a 12-month trailing dividend yield of 1.34%.
Sector Exposure and Top Holdings
