Options positioning implies India’s Nifty may oscillate between 8,000 and 8,600 levels over January series.

Infosys starting the December-quarter earnings season on Friday and technical breakout in banking shares are the key.

January calls at an 8,600 strike see highest open interest among Nifty calls, according to NSE data.

Puts expiring in January at an 8,000 strike see highest open interest among puts.

NSE’s volatility index, domestic equivalent of the VIX fear gauge, at around 13.8 is also low for an earnings month, traders say.
