Many investors keep track of short interest to determine the market sentiment related to a particular stock. Changes in short interest reflect variations in sentiment.

This article will look into a few biotech companies with high short interest ratios.

The Industry

In a recent report, Jefferies analyst Eun K. Yang notes that, as of June 30, weighted average short interest levels fell 0.4 percent for large-cap biotech stocks, 0.2 percent for mid-caps (with market caps between $2 billion and $10 billion), 0.5 percent for small-mid-caps ($500 million - $2 billion), and 0.1 percent for micro-caps.

On the other hand, short interest for small-caps surged slightly (less than 0.1 percent). See Chart 1 for further detail.

Most Shorted Stocks

Large-cap biotech stocks are not particularly shorted. However, among mid-caps, a few companies stand out for their high short interest rates.

According to Jefferies’ report, the most shorted biotech mid-cap stock (despite a slight decline in short interest) is MannKind Corporation (NASDAQ: MNKD)’s, which recently saw 44.9 percent of its float sold short, and 35 days to cover.
