The biotech ecosystem is a continuous conveyor belt from seed funding to IPO, culminating in acquisition by large biopharma. The recent industry-wide stall wasn't a failure of science, but a halt in M&A activity that backed up the entire system.
Unlike in tech where an IPO is often a liquidity event for early investors, a biotech IPO is an "entrance." It functions as a financing round to bring in public market capital needed for expensive late-stage trials. The true exit for investors is typically a future acquisition.
Despite biotech comprising a significant portion of benchmarks, generalist managers consistently remain severely underweight. They perceive this as risk-averse, but it actually exposes their funds to massive tracking error and unintended risks by forcing them to be overweight in other healthcare sub-sectors.
Private VCs with board seats operate deterministically, using their influence to 'make sure' a drug succeeds. Public fund managers operate probabilistically, accepting imperfect information in exchange for liquidity. They must calculate the odds of success rather than trying to directly shape the outcome.
Standard quant factors like expanding margins and avoiding capital raises are negative signals for development-stage biotech firms. These companies must burn cash to advance products, rendering traditional models useless. The only semi-reliable quant metric is Enterprise Value to Cash.
One of the few working quantitative models in biotech is to systematically purchase stocks after they have crashed on bad news. This low-batting-average, high-slugging-percentage approach is terrifying but can work by getting favorable odds on a recovery, provided the company has sufficient cash runway to survive.
In a capital-constrained market, positive clinical data can trigger a stock drop for biotechs with insufficient cash. The scientific success highlights an immediate need for a highly dilutive capital raise, which investors price in instantly. Having over two years of cash is now critical to realizing value.
The biotech sector lacks mid-cap companies because successful small firms are typically acquired by large pharma before reaching that stage. This creates a barbell structure of many small R&D shops and a few commercial giants. The assets, not the companies, transition from small to large.
While biotech seems exceptionally volatile, data shows its average 60% annual peak-to-trough drawdown isn't dramatically worse than the ~50% for typical non-biopharma small caps. The perceived risk is disproportionate to the actual incremental volatility required for potentially asymmetric returns.
