I was thinking on putting down somewhere between 40k - 100k in one of the BRK stocks as an investment and just let it grow quarterly or annually. At an average return of around 14%, that is not bad. Normally in a stock, whether it be a Goog, NYX, CBOT, etc. I usually do not spend more than 5 or 10 percent of my portfolio on the stock. I am usually in a stock either for the ride, or until I hit my price point to get out. Sometimes it is a couple of weeks, sometimes, like HOC, it is a few months. I rarely take a loss. I am willing to stick with the stock until I feel it really is time to exit. On risky companies, like a Goog or Bidu, I just play the options. Anyway, what would be the best way to play a BRKA or BRKB investment long term (over six months to several years)?
