Just remember insiders sell for many reasons- they don't need to explain- and as their portfolios become top heavy since the stock price has advanced, they may be looking for diversification (like all smart investors) OR they may be looking to take a heavy position in something else. The biotech industry in San Diego is rich with start-ups and money moving around. I wouldn't be too hasty deciding to sell based on an insiders. JF has had his fingers in many successful pies. He may just be funding something yu don't know about- yet.I followed Biogen $$ to Illumina and bought when it was less than $5. It iis easy to misinterpret insider sales transactions.The news with SQNM is significant for both companies. They compliment nicely and since I already own SQNM from sub $5, I am adding on today's pullback with this news, since I think the market isn't paying attention.
