From ETF Channel Staff: Investors are actually buying and selling ”units”. These ”units” can be traded back and forth just like stocks, but can also be created or destroyed to accommodate investor demand. Each week we monitor the week-over-week change in shares outstanding data, to keep a lookout for those ETFs experiencing notable inflows (many new units created) or outflows (many old units destroyed). Creation of new units will mean the underlying holdings of the ETF need to be purchased, while destruction of units involves selling underlying holdings, so large flows can also impact the individual components held within ETFs.


Looking today at week-over-week shares outstanding changes among the universe of ETFs covered at ETF Channel, one standout is the SPDR S&P Biotech ETF (XBI) where we have detected an approximate $88.8 million dollar inflow — that’s a 2.1% increase week over week in outstanding units (from 47,350,000 to 48,350,000). Among the largest underlying components of XBI, in trading today Mirati Therapeutics Inc (MRTX) is off about 2.9%, Portola Pharmaceuticals, Inc. (PTLA) is up about 0.7%, and Sage Therapeutics Inc (SAGE) is higher by about 1.5%. For a complete list of holdings, visit the XBI Holdings page »

The SPDR S&P Biotech ETF (XBI) was trading at $90.23 per share on Wednesday afternoon, up $1.40 (+1.58%). Year-to-date, XBI has gained 6.38%, versus a 5.08% rise in the benchmark S&P 500 index during the same period.
