However that&amp;#x27;s not what would happen. If you tried it, your crack would fail, and you would just end up proving experimentally that EMH isn&amp;#x27;t true. That would move the discussion to &amp;quot;is it true except if you test it in weird experiments though?&amp;quot; which is not an interesting point of debate: Obviously there are no market participants with infinite wisdom and processing ability who know all public news and factor it into every stock&amp;#x27;s price instantly at all times, and are…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1011.0423/"&gt;Paper and discussion history&lt;/a&gt;.

I found this article very valuable. In 2010 I put online a brief refutation of the EMH, the efficient market hypothesis. Here it is: https://arxiv.org/abs/1011.0423 If I had seen this then, I think I would have followed the directions in the inset box, where the article suggests saying something like: &amp;quot;The reason I succeeded in finding an algorithm for P=NP is that I noticed that... No one else seems to see that this insight is very powerful. It is very useful since it implies ...&amp;quot; I could have simply written: &amp;quot;Nobody has bothered to test the Efficient Market Hypothesis, but…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1011.0423/"&gt;Paper and discussion history&lt;/a&gt;.

I published this 2-page proof that the EMH is false: https://arxiv.org/abs/1011.0423 (didn&amp;#x27;t set the date so in the document it&amp;#x27;s wrong, this was published 2010.) It doesn&amp;#x27;t depend on P = NP, it&amp;#x27;s simply a rigorous proof that EMH is false. Let&amp;#x27;s switch gears a second. Here&amp;#x27;s a famous elementary proof[1] that there are infinite primes. Suppose there are just finite primes, up to some largest. Multiply them together and add one. No prime divides the new number (because &amp;quot;every&amp;quot; prime leaves a remainder 1), so…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1011.0423/"&gt;Paper and discussion history&lt;/a&gt;.
