A sector fund focused on Healthcare has seen asset inflows in recent sessions that account for about thirty percent of the overall asset levels in the fund as IYH (iShares US Healthcare, Expense Ratio 0.48%) traded more than three million shares in yesterday’s session alone (ADV is about 146,000 shares).

The fund now has north of $1 billion in assets under management, with a chunk of that appearing via new creations lately.

Top holdings in IYH are JNJ (12.30%), PFE (9.53%), MRK (7.15%), GILD (3.98%), and AMGN (3.77%).

Four of these top five components are slated to report quarterly earnings within the next week, with JNJ already having released their results.

IYH is currently trading at new highs, eclipsing a $107 handle yesterday, and since the industry sector seems to be in focus here, it is worth watching related broad based Healthcare ETFs in the space including XLV (SPDR Health Care Select, Expense Ratio 0.18%), VHT (Vanguard Health Care, Expense Ratio 0.14%), and FXH (First Trust Health Care AlphaDEX, Expense Ratio 0.70%) to name a few, each of them having ample exposure to “Big Pharma” names like IYH.
