Risks & Considerations

Clinical Trial Failure

The majority of biotech stocks are clinical-stage, meaning their value relies on FDA approvals. A single Phase III failure can result in an overnight market cap loss of 50-90%.

Cash Burn & Dilution

Non-revenue generating biotechs often face high "burn rates" for R&D. Investors face constant risk of secondary offerings that dilute existing share value.

Regulatory & Patent Cliffs

Even for profitable biotechs, the expiration of key patents or changes in government drug pricing legislation can significantly impact long-term cash flow and valuation multiples.

Sector Concentration Risk

Biotech performance is often highly correlated. Macroeconomic shifts, such as interest rate hikes, can cause broad sell-offs across the entire sector regardless of individual pipeline success.

These risk factors are for educational purposes only and are not exhaustive. Individual investment decisions should be based on thorough due diligence.
