Personally, I'm done adding... Position has become way too big and I find myself questioning my sanity sometimes (down 40%... but who could have foreseen TNBC and BLA delay back in February...). I might be tempted to add at .20 or lower, but I'll fight that temptation and I do hope my willpower won't be tested, lol.

A good lesson for me not to accumulate too aggressively in future investments, even if they seem like an absolute no-brainer...
