The tech-heavy Nasdaq Composite was standing at session lows on Friday afternoon, but was still on pace to notch a record close. The index, up 0.3% at 20,218, marked its lowest point of the day shortly after 2 p.m. The fall mimics the move lower in Alphabet stock, which was down 0.5% and marked a session low. Microsoft and Tesla, two of the biggest companies in the Nasdaq, were down, as well.
