That's good to hear that overall you've made more than you've lost, but you'd have made more taking your dead money here and putting it elsewhere during the last 10+ years - either actively flipping any number of OTC unicorns that frequently pop for a day or 2, or just letting it sit on an actually reliable big board company - and then coming back to CLSI when it truly appears to be doing something. Being in this 10+ years only shows you didn't know when to get out and year after year kept hoping for (as I said) a lucky revival.
Despite all that, this will see a pop again some time but I hope you know when to get out before another 10 years go by.
