Whilst it may not be a huge deal, we thought it was good to see that the Black Diamond Therapeutics, Inc. (NASDAQ:BDTX) CFO, Principal Financial Officer and Chief Business Officer, Fang Ni, recently bought US$61k worth of stock, for US$2.44 per share. Even though that isn't a massive buy, it did increase their holding by 57%, which is arguably a good sign.

Black Diamond Therapeutics Insider Transactions Over The Last Year

Notably, that recent purchase by Fang Ni is the biggest insider purchase of Black Diamond Therapeutics shares that we've seen in the last year. That implies that an insider found the current price of US$2.62 per share to be enticing. That means they have been optimistic about the company in the past, though they may have changed their mind. We do always like to see insider buying, but it is worth noting if those purchases were made at well below today's share price, as the discount to value may have narrowed with the rising price.
