Well, firstly if I were in your shoes, I'd stuff a bunch of newspaper in the toes because I'm a size 10.5 and I'd be tripping over myself all the time.
Seriously though, if it were me, I'd use my favorite risk-management tool: just sell half. "Just sell half" sounds casual, but it works shockingly well in a lot of situations: if you've got a big concentrated position and it's getting a bit worrying, but you're not sure of the right way to handle it, sell half to diversify and let the rest ride. (This is what I did with my Ripple stock: I sold half, and put it into a 60/40 stock-and bond diversified portfolio.)
Because AVGO's listed and it's got an active options market, you can also use options to hedge the remaining half. If you take some of the profits from "just sell half" and spend them on put options covering the remaining half, that'll lock in a "worst-case rate": you have the right to sell the stock at the "strike price" of the option, so if AVGO's stock ends up below the strike price, you can still sell your stock at the strike price and thereby protect yourself from losses below that level. (There are lots of complicated options strategies out there - steer clear of anything more complicated than puts or collars, and if any options strategy tries to offer you "income", run a mile: "income from options" actually means "you're taking on risk somewhere in return for that income, even if you can't see it.)
