What does the market know that I don't? Anyone know what is happening with Aveng, Mid Cap to Small Cap, what's next penny share?
Ben Graham might have had the answer when he said:
"Even though the business that the two of you own may have economic characteristics that are stable, Mr. Market‘s quotations will be anything but. For, sad to say, the poor fellow has incurable emotional problems. At times he feels euphoric and can see only the favorable factors affecting the business. When in that mood, he names a very high buy-sell price because he fears that you will snap up his interest and rob him of imminent gains. At other times he is depressed and can see nothing but trouble ahead for both the business and the world. On these occasions he will name a very low price, since he is terrified that you will unload your interest on him."
TL;DR: The market usually doesn't know much, it just follows emotional flocking , but remember "Markets can remain irrational a lot longer than you and I can remain solvent."
