The Fool responds: One of the tricky parts of investing is believing in yourself and patiently sticking to your convictions. If your research has made you pretty sure that a company has competitive advantages and a bright future, you may have to wait a while before the rest of the market catches on. ARM Holdings, which some see as overvalued at the moment, has rewarded long-term shareholders well. It has averaged a 30 percent annual gain over the past decade.
