S&P Dow Jones Indices today announced the addition in its December quarter rebalance of ASX indices.
Shares in Pilbara have surged by more than 166% since the start of September, with the stock rising from A35.5c to as high as $1.055 on November 30.
Pilbara now has a market capitalisation of $1.54 billion, larger than fellow ASX 200 lithium player Galaxy Resources ($1.41 billion).
Along with Galaxy, Pilbara joins lithium producers Orocobre and Mineral Resources in the ASX 200.
Hartleys this week reaffirmed its buy rating and $1.31 price target for Pilbara.
Rare earths player Lynas Corporation was readmitted to the S&P 200 after being removed in March 2015.
Lynas shares have more than trebled since then as rare earth prices recovered and the company restructured, which included a 10-for-one consolidation this week.
Shares are up by 66% so far this financial year, and the company is now capitalised at $960.3 million.
Foster Stockbroking today rated Lynas as a buy with a 12-month price target of $2.49 per share. The stock traded at $1.752 today.
