The aforementioned ETFs along with the iShares Nasdaq Biotechnology ETF (NasdaqGS: IBB) and the Market Vectors Biotech ETF (NYSEArca: BBH) merit immediate consideration because at least two industry conferences are imminent. As one example, the 33rd annual J.P. Morgan Healthcare Conference starts on Jan. 12, lasting until Jan. 15.

In January 2014, IBB, the largest biotech ETF, surged 8.3%. Investors are already preparing for a big January from biotech ETFs as highlighted by the more than $485 million of inflows to IBB over the past month.

Investors looking for a more conservative way to play a possible biotech bounce this month can opt for the Health Care Select Sector SPDR (NYSEArca: XLV). Not only does XLV, the largest health care ETF by assets, allocate 20.4% of its weight to biotech stocks, bu the ETF is historically the top performer among the nine sector SPDRs in the month of January.
