Here's a recap of a few major headlines that hit the wire over the weekend as investors take stock of the stalling of the market rally and plot their next moves. 

1. Berkshire’s Earnings, Buffett’s Letter: Billionaire investor Warren Buffett-led Berkshire Hathaway, Inc.'s (NYSE:BRKA) (NYSE:BRKB) fourth-quarter results released on Saturday showed a decline in earnings, dragged by investment losses. The development doesn’t come as a surprise given the lackluster market conditions. Buffett’s letter to the company’s shareholders was also released along with the report and it delved into the company’s early days, evolution, investment ideology and future direction.

2. COVID Likely Triggered By Lab Leak, Energy Department Says: The U.S. Energy Department has determined the original COVID-19 pandemic resulted from a laboratory leak in China, the Wall Street Journal reported, citing a classified intelligence report submitted by the federal agency to the White House and key Congressional members. The new report assumes importance because it is based on new intelligence.
