There was a quick reaction yesterday in New York commodity and securities markets to the news of an attack on Cuba.
        There was heavy trading and higher prices in sugar futures on the New York Coffee and Sugar Exchange. The possibility of damage to Cuban sugar properties acted to push world sugar options to new seasonal highs. Prices closed from 2 to 6 points higher on lots of 7,650 tons. A point represents a hundredths of a cent a pound. It was one of the busiest trading days of the year.
        On the New York Stock Exchange issues of companies whose properties have been seized by the Castro Government showed strength. Cuban-American Sugar rose $3.50 a share to $22.875 and American Sugar Refining by $1 to $34.50 a share. On the American Stock Exchange the stock of Havana Lithographing rose 50 cents to $1.25 a share, Trans-Cuban Oil A stock gained .0625 cent to .4375 cent a share and Atlantico del Golfo advanced .375 cent to $3.125.
        Cuban Government bonds traded on the New York Stock Exchange bearing 4 1/2 per cent interest and maturing in 1977 were up $70 for a $1,000 bond to $630. No dollar interest has been paid on these bonds since last Dec. 31.
