That was one crazy first quarter for the biotech sector. Here's where biotech stocks stand on April Fool's Day:


XBI Chart

If you're curious (and I was) about how the biotech ETFs performed during the first quarter of 2014, the   (XBI - Get Report) (SPDR S&P Biotech ETF) was up 9.4%, and the (IBB - Get Report) (iShares Nasdaq Biotechnology ETF) rose 4% versus a 1% gain for the  (SPY) (SPDR S&P 500 ETF). 

No wonder the biotech bubble debate rages on. Watch that downtrend since the middle of March. 

Here are the top-performing biotech and drugs stocks in the first quarter:

5. Anthera Pharmaceuticals (ANTH) +183%
4. Recro Pharma (REPH)+217%
3. Capnia (CAPN) +329%
2. Cormedix (CRMD - Get Report) +415%
1. Aoxing Pharmaceutical (AXN) +432%

It says something about the current state of the biotech sector that I only know one of these companies -- Anthera -- well. I've heard a tiny bit about a second, Cormedix. The other three top-performers are total blanks. Bubble on! 

Better-known stocks with stock prices that doubled or more in the first quarter include: Trillium Therapeutics (TRIL), Esperion Therapeutics (ESPR) and Foundation Medicine (FMI).
