The session yesterday had a lot in common with what is called a day of capitulation. A day of capitulation, which usually occurs after a prolonged decline in the markets, is characterized by a negative start and that is further aggravated by a spiral of sales, with high volume. This spiral of sales is due to the fact that tolerance to loss of most investors is exhausted. These investors after suffering sharp losses in the previous days, decide, emotionally, sell their portfolios at any price. Thus sales of some investors cause sales of others. When this movement leads to extreme prices, many hedge funds, who held positions vendors in the market, start to buy them.
