Global stock markets could crash in October, as by then it will be clear that the economic recovery many people pinned their hopes on will not materialize, the stimulus option will no longer be a viable one, and proprietary trading desks will decide to go short, economist and investor Enzio von Pfeil, CEO of EconomicClock.com, told CNBC.
"The economic time has to worsen and so these green shoots will morph into black shoots very badly, culminating probably in an October crash," Pfeil said.
"People will finally accept that the unemployment rates will have to keep rising, that productivity will have to keep falling," he added. That in turn will make earnings expectations "fall through the floor."
But another analyst rejected his claims, saying predictions of a crash are exaggerated. Anko Beldsnijder, senior portfolio manager at MainFirst Bank, disagreed with the October crash theory.
"A crash - I think that is, in the short term, quite difficult to see because the main problem is a lot of investors are still not in the market, are still very defensively positioned," Beldsnijder told "Worldwide Exchange" in the same segment.
"The key problem is: who should sell for a crash, where should the main disappointment be," he added.
