Halloween is a little more than two weeks away, but the market seems pretty scary these days.
Among the unsettling news on investors' radars—the fear of a pronounced slowdown in Europe; instability in the Middle East and Russia; and new concerns about Ebola, as President Barack Obama postponed a campaign trip Wednesday to meet with Cabinet officials about the outbreak.
As concerning as those catalysts may be, Art Cashin of UBS said investors who are looking for insights into the stock market, shouldn't get too preoccupied with those developments.
Instead, Cashin said the next move will likely be highly correlated to oil prices. "There's a clear link," he said on CNBC's "Closing Bell." "What happens in the energy markets on Thursday will be very important."
