Paraskevidekatriaphobia is the fear of Friday the 13th. For the stock market, however, this 'unlucky' day tends to be relatively calm, with average gains of only 0.2 percent or less.

Below is a look at how stocks traded on this superstitious day.

- The S&P is positive 56% of the time by an average of 0.02%

- The Dow is positive 59% of the time by an average of 0.04%

- The NASDAQ is positive 59% of the time by an average of 0.18%

- The Russell 2K is positive 63% of the time by an average of 0.1% on Friday 13th

Keep in mind that the last Friday 13th (July 13, 2012) was decidedly a very positive day for the market:

- The Dow gained 203.82 points or 1.6%

- The S&P gained 22.02 points or 1.65%

- The NASDAQ gained 42.28 points or 1.48%

Nevertheless, in four of the last five instances, all three major averages finished down on Friday the 13th. Should investors take this as a bad omen?

Probably not. The economic slowdown and fall out from the financial crisis, Europe and debt ceiling may have more to do with the losses rather than superstition.

- The average return for the Dow over the last 5 Friday 13th is -0.16%

- The average return for the S&P over the last 5 Friday 13th is -0.26%

- The average return for the NASDAQ over the last 5 Friday 13th is -0.50%

- The average return for the Russell over the last 5 Friday 13th is -0.70%

Of the top 5 unluckiest Dow components over the last five Friday the 13ths, three are the components that will be removed after the close on September 20, 2013: Hewlett-Packard, Bank of America and Alcoa. The bottom five are rounded out by Intel and JPMorgan Chase.

- Hewlett-Packard is the most unlucky Dow component over the last five Friday the 13ths with an average return of -1.22 percent

And over the last five Friday the 13ths, only 9 out of 30 Dow components have had an average positive return.

The nine components with positive returns are spread out over 4 major sectors: Industrials, led by Caterpillar, up an average of 0.34 percent; Staples, led by P&G, up an average of 0.30 percent; Tech, led by Microsoft, up an average of 0.30 percent; and Energy, led byChevron, up 0.06 percent over the last 5 Friday 13ths.

Telecom, Financials, Utilities, Materials and Health Care companies are absent from the list of Dow components with average positive returns over the last 5 Friday 13ths.
