You might know the tech better, but do you know what people will buy?  That management will take care of the tech well?  That they&#x27;ve hired the right accountants and lawyers to deal with financial and legal issues?<p>I don&#x27;t think people as a whole should avoid buying individual stocks...but I think it&#x27;s probably a good rule of thumb for people. Sort of &quot;don&#x27;t buy individual stocks unless you actually know what you&#x27;re doing.  And 50% of you that think you do are wrong.&quot;
