Recently, Fed Chairman Powell's speech at the Jackson Hole Annual Economic Policy Symposium has attracted widespread attention in the market. Powell's remarks suggested that the Fed might take action to cut interest rates in September, which sparked optimism on Wall Street.

Powell emphasized that future monetary policy decisions will be based on economic data. He specifically pointed out the challenges facing the labor market while also mentioning that inflation expectations remain stable. These remarks were interpreted by the market as a sign that the Fed may ease monetary policy.

David Laut, an analyst at Abound Financial, said: "Powell's speech at Jackson Hole clearly had a dovish tone, indicating that the Fed is ready for a rate cut in September."

Although a jobs report will be released before the Fed's policy meeting in September, Laut believes the Fed already has enough data to support a rate cut decision in September. This view reflects the market's expectations for the Fed's imminent shift to an accommodative monetary policy.

However, it is worth noting that the Fed's decisions still depend on future economic data changes. Market participants need to closely follow the upcoming economic indicators to better predict the Fed's next actions.

Overall, Powell's speech provided the market with new directions for thinking, but the specific policy direction still requires further observation and analysis.
