My friend always finds undervalued stocks

My friend always finds undervalued stocks and he always share the list with others.  The best one he gave was undervalued by 55000 times.  That stock was traded at $1 but his research showed that it was worth $55000.  I was one of his early fans.  At its peak, he had 15 fans.  Years later, we found out that our performace was not even as good as the market.  He still share his list with people these days.  Old fans were replaced with new fans.
