Big Tech earnings this week are the real test. The playbook in India—banks leading while tech lags—may not play out the same way in U.S. stocks. Whether all that AI spending can turn into profits comes down to the guidance from these companies.

I’m leaning toward soft guidance, and I hope I’m wrong—because if I am, it means the rally is still alive. Keep an eye on these companies.
