On Thursday we may all get to live through a truly momentous market event.
The S&P 500 is hovering close to 2,058.90, the close at the end of the last year. We could land exactly on that number and break even exactly for the year. That has only happened once since 1929 — in 1947. The S&P 500, in its current form, launched in 1957, but S&P uses historical data to track how the index would have performed going back to the 1920s.
