AMD Tech companies have been enjoying a strong run, but Morgan Stanley says the sector is more likely to revert to the near-term mean soon.Tech stocks rose in pace with the broader market Monday, ahead of what’s expected to be a relatively strong earnings season, but Morgan Stanley is starting to see leaks in the sector’s gas tank. Tech stocks on the S&P 500 index SPX, +0.88% rose 0.8% while the broader index finished up just shy of a 0.9% gain. Much of the drag on the tech sector came from shares of Twitter Inc. TWTR, -5.38% which fell 5.4% after a report of account suspensions. For the year, the S&P 500’s tech sector has gained nearly 14% while the broader index has advanced 4%. Those days of strong performance are numbered, Morgan Stanley said in a note headed by equity strategist Michael Wilson. The analysts downgraded the tech sector to underweight from equal weight, Morgan Stanley’s second downgrade for the sector this year, amid a growing number of red flags for the sector. “In our experience, rolling bear markets are not over until they have touched every last corner, with the highest quality areas often coming under pressure at the end,” the note said. “Given its exceptional growth and quality characteristics, Tech has been a holdout to date.”via
