RE:Latest news very goodA buyout by Roche could happen anytime.
It needs to happen very soon otherwise ONC is facing a capital raise that will decimate existing shareholders.
No one "invests" by buying shares in ONC at this time. It is a pure speculative gamble with a timeframe of less than two months.
Roche buyout... you win at least 10x
Dilutive financing ... you lose half your money, likely never to see it recover.
Given that MC is CEO, I place the odds at less than 5% in favour of buyout.
With any other CEO, ONC might be worth a small gamble at this moment.
