Telsa Inc.'s  (TSLA) - Get Tesla Inc Report  rough weekend has extended into Monday. 

JPMorgan on Monday, Aug. 20, slashed Tesla's price target to $195 from $308, saying that it appeared "funding has not been secured" for CEO Elon Musk's proposal to take the electric vehicle maker private. The analysts initially had boosted Tesla's price target after a tweet from Musk on Aug. 7, said he was considering taking Tesla private.

The price slash came after a report over the weekend that Saudi Arabian sovereign wealth fund, PIF -- Musk said he believed Saudi Arabia's PIF could provide the necessary funding -- was planning to sink $1 billion into Tesla competitor Lucid Motors Inc., a company that was started by an ex-Tesla board member.

Tesla shares were down slightly when the market closed.
