Why Vedanta's demerger turned aluminium into the top leg

For existing Vedanta shareholders, the demerger is a liquidity unlock. Each new listed entity will have its own free float and its own investor base. A dedicated aluminium stock could attract sector-specific funds that would never buy the broader Vedanta conglomerate. The same logic applies to the zinc and oil-and-gas businesses.

The downside risk is execution. Splitting the balance sheet, untangling inter-company loans, and transferring contracts across six separate entities takes months. Any delay in the National Company Law Tribunal approval process would push the record date further out. The stock has already priced in a smooth timeline; a legal hiccup would hit the valuation gap.

Vedanta's founder and majority owner, Anil Agarwal, retains control of all entities after the demerger. That limits the corporate governance upside. Minority investors still rely on Agarwal's decision-making for capital allocation and dividend policy. No independent board exists at the new aluminium arm yet.

The next concrete marker is the NCLT hearing schedule. Until the scheme is approved, an arbitrage trade exists between the Vedanta stock price and the implied value of the six parts. That gap has already narrowed from the initial 80% premium to about 67%. It will close further as each legal milestone passes.

For traders, the aluminium arm's relative valuation is the number to watch. If it commands a multiple in line with global aluminium producers like Alcoa or Norsk Hydro, there is still room above the current implied value. If Indian-listed metals traders assign a domestic discount, the rerating may be mostly done.
