# $SPX 100 Point Thresholds

With S&P 500 Index ( $SPX) crossing above 1700 for the first time ever today, below a table with the details of how many calender days it took to conquer each new round number since 4th Jun 1968 , when $SPX crossed above 100 for the first time.

In the table below, we also list the first day that the $SPX closed above each 100-point threshold from 100 to 1700 , and what were the returns over the next 1/5/10/20 trading days.

*ps: we know that a jump from 100 to 200 is indeed 100% gain , while a jump from 1600 to 1700 is only 6.25% gain , but the point is we are trying to see how those big new round numbers which were widely-watched and that have some psychological significance to factor in behaved in the past *

*pps: there were few successful traders like Monroe Trout who likes to trade the “magnet effect”- the tendency of markets to get to round numbers.*
