It is fine, then sell out and you may buy back at a higher price later. Your money, your call. I personally expect this trial - assuming what is the likely outcome that it will be successful - will end well before that. The US - and other countries are opening - there no COVID-19 vaccine at least till the end of the year and countries go broke and people bonkers with the lock down, lots of people still dying, so there is plenty of political pressure to have a treatment ASAP to allow a safer way of opening up. Just my view and happy to sit and hold and accumulate when I can and when Mr Market is silly.
