Biotech is one of the very very very few areas of the stockmarket where specialist knowledge generates alpha.
Trolling through random biotechs, learning about their tech, and investing in the most promising applications of that tech in the most impactful areas is something that happens somewhat on publicly traded markets. With tech, most of that happens pre-IPO.
It’s similar to the situation where a company puts out a public offer to buy another company at say, $50 a share on a day that the acquisition target is trading at $40/share.
If the stock of the target company is trading at $46/share, the market is pricing in the probability of the acquisition not happening. If the market knew the acquisition would happen with 100% certainty, the price of the target company shares would be equal to the buyout share price offer. You can assume the risk of the acquisition not happening by purchasing shares at $46, and if it does end up going through, you earn $4 a share from assuming that risk.
