It is unlikely that directors has been unable to make insider purchases for extended periods of time, yet in the last 10 years there have been none other than an odd 1,000 share purchase by Dr Lebby after he received his $2.6m cash bonus for 2021.
If the wild projections of 10 or even 50x the current stock price within the next 2-4 years is even close one would expect insiders to buy up all the shares they can at market. But since those have to be reported, we know that isn't happening.
Instead we saw significant SELLING by every director early in 2022 (over $1 million in some cases).
