CM Jayalalithaa's  health is already impacting stock markets today. SUN TV saw its stocks rise corresponding to news of Jayalalithaa's decline. The channel is owned by Kalanithi Maran, Karunanidhi's grand-nephew, and serves as a DMK mouthpiece, the rival party to the Jayalalitha led AIADMK.

In Tamil Nadu, the local news is notoriously politicized, and the state has long seen a tight link between politics and entertainment, with three CMs so far from the local movie industry. The market is clearly expecting a rise in fortunes for Sun TV if Jayalalithaa's illness worsens. Jayalalithaa has long been AIADMK's dominant leader, and her absence would set the party's fortunes among voters in question. 

Another company, Trent, has also emerged as one of the top gainers in markets today after weeks of decline - rising over 8% in morning trading. Trent's sudden recovery in the stock market suggest that Noel Tata - who is the Chairman of Trent and Ratan Tata's half brother - is seeing his chances improve for the top post. The likelihood of Mistry holding on to his role in the Tata companies where he is still on the board or is Chairman, has been diminishing in recent weeks as Tata Power and TCS have taken steps to remove him as the director.
