Tech stocks’ rebound helps markets reach new highs

Apple and other big-name technology stocks got back to their winning ways Mondayandhelpeddriveu.s.indexes once again to record heights.

The Standard & Poor’s 500 index rose 20.31 points, or 0.8 percent, to 2,453.46 and surpassed its old record, set nearly a week ago, by half a percent. The Dow Jones industrial average added 144.71 points, or 0.7 percent, to 21,528.99, and the Nasdaq composite jumped 87.25, or 1.4 percent, to 6,239.01.

On Monday, Apple rose for just the second time since two Thursdays ago. It jumped $4.07, or 2.9 percent, to $146.34 for its second-best day of the year so far. Google’s parent, Alphabet, rose $16.60, or 1.7 percent, to $975.22. Altogether, tech stocks in the S&P 500 rose 1.7 percent, the largest gain among the 11 sectors that make up the index.

It’s just the latest example of investors steeling themselves and “buying the dip.” Every time the stock market has shown any weakness in the past eight years, it’s proven to be a good move for investors to buy. That’s because stocks have ended up erasing any losses incurred, only to move higher. That long track record has trained investors to pounce whenever they see a dip, and analysts have noticed how ingrained the instinct has become.

“It’s concerning, but I don’t see what breaks it at this point of time,” said

Nate Thooft, senior portfolio manager at Manulife Asset Management. “For the time being, investors are thinking, ‘We can’t afford not to be in this market, and we’ll continue to play along with the dynamics of the gradual melt-up.’”

Thooft expects stocks to continue rising, even with prices high, because bonds look less attractive. Plus, profit growth is improving for companies, which helps to justify their stock price gains.
