Corporate insiders doing a huge amount of selling, relative to buying, thei company's shares.

I used to report the insider sell versus buy ratio in my ECONOMIC LOGIC newsletter  for many decades. 

But now I prefer looking only at the very large buys and sales by insiders (corporate officers only, not including 10% owners, such as mutual funds). 

 

I define large transactions as being over $5 million, and a 30 percentage point or more change of the executive's total holdings of company stock.

 

These large trades have been bearish since Labor Day 2020.
