If you think Insiders not buying on market is a catalyst, maybe you should tell Munger or Buffet, whom have applied this tested principle for nearly 60 years. Or try a couple of these other Master Investors

“Sometimes the only thing standing in the way of a cheap stock and a profit for an investor is a catalyst that can make the market take notice. Both insider buying and activist investors can provide the push that makes the market realise a stock is good value” Christopher Browne

"Passage of time at a low valuation, assuming reliable cash flows and a durable franchise ranks as an important catalyst. However we look for other catalysts as well, including asset divestitures, smart synergistic acquisitions, share buy-back programs, dividend initiations, analyst upgrades, insider buying, judicious capacity expansion in growth markets and others - the more catalysts the better" Alex Roepers

You also unfortunately have not dis-proven the logic of the sales shape build either.
