However you might want to talk to somebody about setting up a 10b5 plan or talk to somebody knowledgeable to see if it would even make sense. My understanding is these plans are created exactly to avoid the situation that you're in where you want to sell some of your equity but you might hold insider information.
The way it basically works is that you can set rules as to when you want to sell your stock but in the future. For example you might say 6 months from now as long as the stock is over $50 sell it.
The fact that you are establishing the rules in which a sale would execute means that you would not know what the stock price was going to be 6 months from now. Since it's all set way in the future you shouldn't be accused be accused of insider trading, you would have no idea where the stock is going to be in 6 months.
This is how many high level executives sell their equity since they would always have insider information.
When nice thing about this is I think you can even sell during a blackout.
The downside is that you lose the flexibility if the stock was to pop up 200% tomorrow you couldn't sell it since you would not be able to sell on the open market you would be selling through your plan.
Again I've never used one of these so I might not have it correct but I think it's worth talking to somebody about whether this would solve your problem.
