Our read on IBB
ABiotech's original index fund. Since 2001 IBB has packed the whole US biotech sector, roughly 250 names, into one line item for 0.44% a year, below what the typical biotech fund charges.
The Fund seeks to track an index composed of U.S.-listed equities focused on the biotechnology sector.
Why people hold it
- A 2001 launch makes it one of the sector's originals, and it has grown into a multi-billion-dollar fund that trades actively.
- Roughly 250 stocks, so the whole US biotech bench comes along instead of a few marquee drugmakers.
- 0.44% a year, set by the prospectus and below the median fee in its biotech peer group.
- Sticks closely to the job in its prospectus: US-listed biotech equities, nothing exotic bolted on. That lands it in the upper half of its peer group.ishares.com
Worth knowing
- Cheaper seats exist in the same aisle: IBBQ at 0.19%, BBP at 0.34%, XBI at 0.35%.
- One industry carries the whole fund. Trial readouts, FDA decisions and patent expiries drive it, with no other sector to cushion a rough patch.
- Distributions arrive quarterly, but biotech is a growth sector and payouts are a side effect, not the point.
