On the optimistic side, Ryan Detrick, senior market strategist at LPL Financial Holdings Inc LPLA acknowledged that while the charts look similar, there are also several differences including the factors leading up to what caused the 1987 crash.

More pessimistic, market technical analyst Murray Gunn of HSBC Holdings plc (ADR) HSBC warned that the 2,116–1,991 range by the S&P 500 or the 17.992–17,063 mark by the Dow could trigger a big selloff.

Key Differences Between 1987 And 2016

Before Black Monday, the S&P 500 was up nearly 40 percent before the crash happened, much different than the year-to-date results seen in 2016.

"The bottom line is no two years are ever the same and to suggest they are is uninformed," said Detrick, according to Market Watch.
