– The ‘win’ rate so far this century: 83% –

By Simon Maierhofer, MarketWatch

Here are stats on the most bullish S&P 500 Index trading day of the year since the beginning of the new century:

  • When: First trading day of July (in 2018, that’s July 2)
  • Average return: 0.35% (see chart below for more details)
  • Win rate: 83.33%

The win rate for the Dow Jones Industrial Average is 77.77%. The win rate for the Nasdaq is 72.22%. So the S&P 500 is the winner.

S&P 500 day traders may be content with 83.33% odds, but investors might be wondering if July 2, 2018, could be more significant longer-term.

S&P 500 seasonality

It may come as a surprise that the best trading day of the year happens in the middle of what many consider a seasonally weak period of the year: the summer doldrums.

The chart below provides some clarification and context. The black graph represents S&P 500 seasonality based on all years since 1950.

The blue graph illustrates mid-term election year seasonality (2018 is a mid-term election year).

The first half of July tends to be mildly bullish, and often hosts a brief summer rally. Keep in mind, though, that the summer rally tends to be the weakest of all seasonal rallies.

In mid-term election years, the S&P 500 doesn’t get going until October.

Based on seasonality, the best trading day of the year has the potential to kick off a one- to three-week bounce.

After this week’s drop, investors may hope for seasonality to provide a “shot in the arm,” but the truth is that seasonality is only one of many factors that affect stocks.
