It is better to be diversified. It is never good to invest in only one stock, no matter what that stock is. Anything can happen and a stock could suddenly become worthless. In fact, virtually all stocks will eventually go to zero if given enough time. But the total stock market will never go to zero and will continue to gain in value over time.
