If history is any guide, stocks won’t change much when the exchanges re-open, now scheduled for Wednesday.

CNBC compiled a chart of the last 13 emergency-related market closures going back to 1945. On the day that the market re-opened, the Standard & Poor’s 500 inched down an average of 0.05 percent, and the Dow Jones Industrial Average eased 0.17 percent.

If the markets match that average when they re-open now, the S&P 500, currently 1,411.94, would shed less than a point. And the Dow, now 13,107.2, would fall 22 points.

The CNBC compilation spans from the end of World War II to the mourning for former President Gerald Ford in 2007.

The biggest drop came after the four-day closure for the terrorist attacks of Sept. 11, 2001. When the markets re-opened Sept. 17, the S&P 500 fell 4.9 percent, and the Dow plunged 7.1 percent.

The market’s biggest gains came after former President John F. Kennedy’s funeral in November 1963. The S&P 500 soared 4 percent, and the Dow jumped 4.5 percent.

This week represents the first unscheduled, multi-day, weather-related NYS
E closing since the blizzard of 1888.

Among stocks to consider when the market re-opens are generator makers, such as Generac and Briggs and Stratton, according to Bespoke Investment Group.

It also suggests home-improvement chains, such as Home Depot and Lowe’s, along with property and casualty insurers, which should have room to raise their rates.
