NEW YORK, New York – U.S. stocks were in and out of positive territory Monday, but in the end, all bourses managed to finish in the black.

Earlier gains evaporated when U.S. long-term Treasury yields surpassed a 3 percent yield, but a strong burst of buying of over-sold technology stocks pushed the major indices higher.

“Treasury yields are currently reflecting an aggressive Fed tightening mode,” Oliver Pursche, senior vice president at Wealthspire Advisors in New York told Reuters news agency Monday.

“The question on investors’ minds is how flexible and willing to take their foot off the pedal will the Federal Reserve be?”

The Nasdaq Composite did best at the finish, rising 201.38 points or 1.63 percent to 12,536.02.

The Dow Jones industrials gained 84.29 points or 0.26 percent to 33,061.50.

The Standard and Poor’s 500 added 23.45 points or 0.57 percent to 4,155.38.

The U.S. dollar’s strength remained intact with the euro slipping further to 1.0504. The British pound sank to 1.2488. The Japanese yen softened to 130.19. The Swiss franc dived to 0.9782.

The Canadian dollar weakened to 1.2878. The New Zealand dollar dipped to 0.6432. Only the Australian dollar weathered the storm Monday to finish largely unchanged at 0.7051.

On overseas equity markets, the UK, China and Hong Kong bourses were closed for public holidays.

In Germany, the Dax dropped 1.13 percent. The Paris-based CAC 40 was off 1.66 percent.

The Nikkei 225 in Japan declined 29.37 points or 0.11 percent to 26,818.53.

The Australian All Ordinaries fell 101.20 points or 1.31 percent to 7,623.60.

In New Zealand, the S&P/NZX 50 dropped 99.94 points or 0.84 percent to 11,784.36.

South Korea’s Kospi Composite retreated 7.60 points or 0.28 percent to 2,687.45.
