Small-cap biotech stocks are in a rut, confirming the frustration expressed by a number of biotech investors and traders these days.
Before I dig into specific numbers, let's pull back for some perspective. Biotech stocks overall are still trouncing the broader market this year, so complaints about small-cap biotech stocks is a bit of a first-world problem.
Admittedly, the picture doesn't look as pretty for the past three months.
The orange line represents the iShares Nasdaq Biotechnology ETF(IBB) - Get Report , which is more heavily weighted toward large-cap biotech stocks. In contrast, the SPDR S&P Biotech ETF(XBI) - Get Report (blue line) includes many more small-cap biotech stocks. In the last three months, the XBI is down almost 3%, underperforming the IBB and the S&P 500.
To dig into the diverging performances of small- and large-cap biotech stocks, I ran two screens using S&P Capital IQ. The first screen identified biotech stocks trading on major U.S. exchanges with market capitalizations of $500 million or greater. This was my proxy for large-cap biotech stocks, although admittedly, my market cap cutoff is somewhat arbitrary. The screen identified 165 stocks. The average return for these large-cap biotech stocks in the past three months was 5%.
The second screen picked up 279 "small cap" biotech stocks trading on major U.S. exchanges with market caps below $500 million. The average three-month performance for these stocks: -19%.
There's your divergence. If you feel like it's harder to make money in small-cap biotech today, you're right, it is.
In case you're wondering, the best-performing, small-cap biotech stocks for the past three months are Ambit Biosciences (AMBI) , iBio(IBIO) - Get Report , Esperion Therapeutics(ESPR) - Get Report , OvaSciences (OVAS) and MediciNova(MNOV) - Get Report . Worst performers in the sub-group: WaferGen Biosystems (WGBS) , Sunesis Pharma(SNSS) - Get Report , Cytori Therapeutics (CYTX) , Cellectar Biosciences(CLRB) - Get Report and Alcobra (ADHD) .
