It should be a new high in the next year. The stock is always higher one year out, it's how it works for management to keep cashing the options that are always getting replaced.
Long term this is a good stock. Since management has options that expire every year, the stock needs to be up a calendar year out. The float is very small so management can influence the stock price with buybacks and planned misses caused by the timing of things like advertising.
With Koch's separate class of shares, it's almost like a private company that needs the stock price to keep bouncing up and down to make the options game work better. For it to work indefinitely the stock needs to go up year after year which is obviously good for investors that hold shares. If trouble ever really happens, Koch can decide to sell out for big money.
Once they start buying back the stock, it will bounce back up. The options always have to end up in the money, so the small float allows management to play around with the stock quite a bit. They buy back low, then sell the options high. It's been going on for years, but the positive is it has to be up a year out for the option ATM to work. Watch for an increase in the buyback shortly.
