Or, from another field: it might look like some stock investors are &quot;hot&quot; or &quot;cold&quot;, but that doesn&#x27;t mean that investing with a currently-&quot;hot&quot; investor will give you any better odds. The variance in the market is high; sometimes people get a streak of wins without that being any more than luck.<p>(Some people, like Warren Buffet, do more; but if you know enough about their strategies to differentiate between the people getting lucky and the people &quot;playing smart&quot;, you know enough to do your investing yourself.)
