The Nasdaq and S&P 500 rose to a fresh record highs on Monday to close out a mixed trading session, with the Dow and slipping lower, ahead of the Federal Reserve's key monetary policy decision later this week.

S&P 500 Index (SPY  ): +0.18% or +7.74 points to 4,255.18

Dow Jones Industrial Average (DIA  ): -0.25% or -85.39 points to 34,394.21

JPMorgan Chase stockpiling cash to prepare for long-term inflation:

JPMorgan Chase (JPM  ) CEO Jamie Dimon stated during a Monday conference that the investment bank is "effectively stockpiling" cash due to the possibility the higher inflation will force the Fed to raise interest rates,CNBC reports. The bank has positioned itself to benefit from raising interest rates, Dimon added.

"We have a lot of cash and capability and we're going to be very patient, because I think you have a very good chance inflation will be more than transitory," said Dimon, quoted by CNBC. "If you look at our balance sheet, we have $500 billion in cash, we've actually been effectively stockpiling more and more cash waiting for opportunities to invest at higher rates. I do expect to see higher rates and more inflation, and we're prepared for that."

Here's how the market stood in the afternoon:

S&P 500 Index: -0.24% or -10.34 points to 4,237.10

Tesla to accept bitcoin for purchases again in the future:

Over the weekend, Tesla (TSLA  ) CEO Elon Musk tweeted that the electric vehicle company plans to resume accepting bitcoin as payment for vehicle models after the cryptocurrency becomes more climate friendly, boosting the digital currency back above $40,000.

"When there's confirmation of reasonable (-50%) clean energy usage by miners with positive future trend, Tesla will resume allowing bitcoin transactions," Musk tweeted in reply on Sunday.

Earlier this year, Tesla had revealed in an U.S. Securities and Exchange Commission (SEC) filing that it had purchased $1.5 billion worth of bitcoin and would begin accepting it as a payment method for its products. However, the company paused car purchases with bitcoin over concerns over mining energy use.

Musk has become a market-mover for the digital currency, with his comments having the power to sway trading.
