In this video as part of our Ask a Fool series, Motley Fool One advisor Jason Moser takes a question from a Fool reader, who asks, "Why would a winning stock that has had a good run and now makes up a bigger portion of your portfolio, mean that there is a greater risk? Heard this argument on Market Foolery the other day. Doesn't make sense to me."
