Tesla Inc. (NASDAQ: TSLA) shares have lost about 42% in the year-to-date period. Undeterred by the sell-off, certain members of the U.S. Congress have been trading the stock in recent months, according to data provided by Capitol Trades, a website tracking trades by lawmakers.

What Happened: Since August, three lawmakers — Rep. Ro Khanna (D-Calif), Rep. Chris Jacobs (R-NY) and Rep. Kathy Manning (D-NC) — made 14 trades in Tesla sock with the value of the transaction potentially totaling up to $315,000, Capitol Trades database showed.

Members of Congress are required to report the size only as a range. Khanna executed the most number of trades during this three-month window. In late September, he bought stock worth between $15,000 and $50,000, and in October, he disposed of Tesla shares in two transactions, valued at $1,000-$15,000 each.

The biggest buy of recent months was made by House Speaker Nancy Pelosi, who bought Tesla shares worth $1 million to $5 million on March 17 with the trade reported four days after. The owner has been mentioned as her husband Paul Pelosi. The stake has not been offloaded since then.
