TCS has not declared the date but two things stand out.
1. TCS ATM IV is increasing everyday since 4 days and IVR is at 79-80.
2. TradingView chart shows 9th Jan as Result day.But Moneycontrol,motilal oswal calendar does not show that date.
its common for IV to increase everyday running upto earnings .. Happens with most of the stocks if not all...
sometimes, some sites take last year or quarter's earnings date and show it as this month's date.. so beware of that ...
i did a quick check on Infy .. i dont think short straddle would make money .. current straddle is about 45... i expect this to be 45+ till earnings specially if Infy is the first one to come...
DONT trade on it .. just my view looking at the prices... I remember in July 2019 it was bit low and Infy made a move post result... I skipped Infy in July.... Oct i went short straddle in Infy and stayed through the result ....
P.S: if one decides to go long straddle he should know how to scalp gamma... without that knowledge Long straddle is usually very risky and low probability trade!
