The cyclical bull market for equities is over; after December, stocks will begin a secular multi-year decline, starting with a 40% correction by April, said Harry Dent, founder of HS Dent."If we see another new low in the stock market, I predict we are not going to see new highs on the Dow, S&P, NASDAQ, biotech, you pick anything...you're not going to see new highs on anything for decades," Dent said.
