Check out the companies making headlines in midday trading:

Tesla — The electric automaker's rose 3.8% and, during midday trading surpassed $420 a share, about 16 months since CEO Elon Musk tweeted that he had "funding secured" to take the company private at that price.

3M — Shares of the industrial conglomerate rose 1.8% after J.P. Morgan upgraded its rating on 3M to neutral from underweight. J.P.
