Prices of bitcoin dropped to around $46,000 after the U.S. Securities and Exchange Commission clarified on Tuesday it had yet not approved ETF trading for the cryptocurrency.

Bitcoin had shot up to almost $47,000 after a false post from the SEC's X account said the regulator had approved bitcoin ETFs for trading. 

However, an SEC spokesperson told CNBC that its X account had been compromised, and the post regarding bitcoin ETFs was not made by the SEC or its staff.

Following the SEC's clarification bitcoin dropped to about $45,400, before recovering slightly.

X confirmed that the account was compromised, but added that it was not due to any breach of the company's systems.

Shares of Juniper Networks jumped more than 23% in premarket trading Tuesday, continuing to rise after the Wall Street Journal reported on Monday evening that cloud-services provider Hewlett Packard Enterprise is in "advanced talks" to acquire the company for about $13 billion.

A deal between the two companies could be announced as soon as this week, the Journal reported. The acquisition could bolster HPE's efforts to challenge Cisco, which has long competed with Juniper in the networking equipment market.

Juniper's stock price underperformed the tech industry last year, losing about 8%. HPE added nearly 10%, on the other hand.

Oil prices bounced back Tuesday after yesterday's selloff.

The West Texas Intermediate futures contract for February rose $1.47, or 2.08%, to settle at $72.24 a barrel. The Brent futures contract for March gained $1.39, or 1.76%, to trade at $77.46 a barrel.

The two benchmarks settled more than 3% lower on Monday after Saudi Arabia slashed crude prices to Asian customers by $2 a barrel, heightening fears about global demand.

"Volatility is high and if you don't like the price just stick around," Phil Flynn with the Price Futures Group wrote in a note Tuesday morning.

Flynn said prices are bouncing back Tuesday because the selling yesterday was "out of balance."

Geopolitical risk also persists as tensions rise in the Middle East and Libya's largest oilfield remains shut down.

The move mirrored lower shortfalls in both imports and exports on the month. Economists surveyed by Dow Jones had been looking for a deficit of $64.7 billion.

The goods deficit with the European Union decreased to $15.6 billion and to $21.5 billion with China.
