Delaware Senator Thomas Carper is an active trader.

In March, he purchased shares of Arcadium Lithium $ALMT, a company in the lithium production industry. 

Notably, Senator Carper sits on the Finance Committee’s Subcommittee on Energy, Natural Resources, and Infrastructure.

Literally days after his purchase, the company was in talks to be acquired.

$ALMT has been up since then.

Earlier in the year he reported that his spouse invested in Valero Energy Corporation, $VLO, in January.

Within three months the position was sold, netting an impressive ~38.1% gain.
