But will a potential US slowdown impact the earnings and value of the Indian IT services sector? J M Morgan Stanley analysts see no such indicators. They reason that new customer-wins are strong, existing customers are ramping up, and management teams appear to have high visibility.

However, what if the US slows significantly going forward? Analysts opine that this sector can be resilient to an extent, but there will be an impact nevertheless.

The larger scale of the companies, a more diverse revenue base, and widespread acceptance of offshore outsourcing now may be mitigating factors relative to the 2001 slowdown.
