Well, one can dig deeper than this ... earnings season is an opportunity for those who do the hard work... it happens 4 times a year .. 4 months of extra money..
while 8 trades r too small a sample to trade anything (this time INfy coming before tcs?) but there is a meat there which is not very straightforward... like mkt direction a trader has to take a view on the price of the straddle to make money pre, during and post earnings(iv crush) ..
coming to TCS, Infy cases : these days TCS r declaring result before Infy .. hence the above phenomenon .. there was a time when it was reverse , Infy used to come out before TCS ... and many times i made money by going long straddle in Infy .. so the point is dont trade blind , understand what causes the result and should the environment changes , recog it and change with it.. if one does not know why this setup work he would fail to see the change coming and keep trading even after setup changes such as sequence of earnings of same sector cos etc etc. ...
I see Infy on 10th but TCS date is not announced?
