Honestly management is already sitting on a goldmine of options. If they wish to, they'd cash in in the millions, at the expense of us shareholders. They chose not to.
Ofc as a shareholder I'd love to see Suresh and co. buy some through option exercise, but that's their freedom. I'd LOVE to see it but I don't feel right pressuring them to do so.
All I could ask for is for them to continue what they're doing to grow this company organically to its billion dollar valuation. When that day comes, and I hope soon, we won't have to worry about whether management owns too little or too much.
There are other companies with huge insider ownership + institutional ownership and are still going down day by day, for example Desktop Metal (idk, just a random pick). It shows that while management ownership may be a good thing, it doesn't translate into a stock doing well.
