A selloff that rocked equity markets around the world is clouding the outlook for investors looking to buy stocks on the cheap.
Bill Ackman's main hedge fund, Pershing Square Holdings, has seen its gains for the year basically evaporate.
Longtime market and economy watcher Ed Yardeni said that the current global equities selloff bears some similarity to the 1987 crash.
Stocks tanked on Monday, continuing losses from the past several trading sessions as fears about a weakening economy gripped markets.
