This is how you "buy low"..............

"It is well known at the Stock Exchange the public at large buys only in a rising market and sells in a declining one. The financiers who, because of their greater practice in this business, use their reason to a greater extent, although they too sometimes allow themselves to be swayed by sentiment, do the opposite, and this is the main source of their gains." 
-Vilfredo Pareto, The Rise and Fall of Elites
