Sentiment, I did the same. Initially I was just in IMUC, but when I looked at competitors, NWBO came to my attention. With what appeared to be about equal prospects in GBM, the thing about NWBO that attracted me was DIRECT. So, I spread my eggs pretty equally between the two baskets. My gut told me to put more into NWBO, but I held hope for a good Phase II result on IMUC only to be disappointed with the results announced in Dec, 2013. I lost a bundle on that one, but fortunately got our when it was in the $1.40 area. I am all in on NWBO, and don't expect the same outcome on their trial results. Just wish I listened to my gut 18 months ago.
