Ekso Bionics Holdings Inc (EKSO)

[Rhetorical]

Please consider preferred stock and stock options. Looby may not be sitting on many shares of common stock, but he might have the options to acquire large amounts of preferred stock which he can then turn into common stock. His options likely don't expire for some years to come - so he might be holding on to them for more ideal timing.

Remember that when Microsoft got part of apple, they exchanged preferred stock to common stock at incredible ratios.

"Microsoft's $150 million investment netted the company 150,000 shares of preferred stock, convertable to common shares of Apple stock at a price of $8.25, redeemable after a three year period. By 2001, Microsoft had converted all of its shares into common stock, netting the company approximately 18.1 million shares. "

It might honestly help Ekso that Looby's not converting his options into shares although somewhat counter-intuitive at first glace looking at insider trading activity. The timing issue might be immensely more important than the benefit of having the shares currently (simply declaring losses to offset income tax)
