The CEO of Goldman Sachs expects the next wave of initial public offerings in tech companies to help stimulate the U.S. stock market.

David Solomon has responded to a series of critical comments in news reports in recent weeks, saying it’s “not fun” to face personal attacks, according to an interview on CNBC.

He said in the interview: “I don’t recognize the caricature that’s been painted about me, and when I talk to my colleagues and clients, they don’t recognize it either.”

He continued, “But that doesn’t stop me from thinking about anything that’s been said, and I’m always trying to think about how to do a better job.”

Salomon pointed out that if initial public offerings, including holdings arm of Softbank, do well, this will trigger more activity in the stock market.

Solomon asserted that trust among company CEOs has improved, leading to an increase in mergers and acquisitions. But he cautioned that the pace of implementation would be slow.

“The economy is more resilient than people, including myself, expected,” Solomon said, “and the sentiment I’m hearing broadly from CEOs is, you know, it’s time to get back to that.”

Goldman maintains its core savings business at Marcus, which has more than $130 billion in deposits, Solomon said.
