The most informed group in the US stock market quickly bought the dip, with net buying volume surging to a new high since May.

Since April, the U.S. stock market has experienced its worst decline, but this has triggered a buying frenzy among one of the market's most informed groups: corporate insiders. Over the past 30 days, executives of publicly traded companies have been buying their own company's stock at the fastest pace since May. They entered the market during a period of panic, when concerns about an artificial intelligence bubble triggered a shift of funds from overvalued tech stocks to more defensive sectors. This surge in insider buying has provided some comfort to bulls. Previously, the S&P 500 fell 3.1% in a week and was heading for its worst month since April. These executives bought when other "bargain hunters" seemed hesitant, and recent five-day losing streak in U.S. stocks has seen intraday rallies quickly wiped out. (Jinshi)
