While VST stock looks attractive given its winning streak, investing in a single stock without detailed, thorough analysis can be risky.

Why is that? As a group, HQ Portfolio stocks provided better returns with less risk versus the benchmark index; less of a roller-coaster ride, as evident in HQ Portfolio performance metrics.
