Corporate Executives

I’ve been working my entire career to climb the corporate ladder and get to where I am now.  I enjoy my job and want to continue to work.  Most of my wealth is tied up in my company (in various instruments) which concerns meWhile I’ve got great confidence in my company I know it’s important to diversify since circumstances can change unexpectedly. I’m not sure I know what to do.  How I can I slowly diversify over time while keeping my position protected? How much should I sell and when do I do it?  What will be the tax consequences and how do I minimize them?

How do I slowly diversify out of my company position while remaining protected from devastating market downturns?
