Morgan Stanley remains top of the list in Institutional Investor’s fifth annual ranking of Asia’s best corporate access providers.

The firm has ranked first in each iteration of the survey, last year tying with Bank of America Merrill Lynch and Credit Suisse for providing the greatest access to Asia’s corporate leaders.

This year’s revamped rankings, based on responses from the broader All-Asia Research Team and All-Asia Executive Team surveys, found Morgan Stanley pulling ahead of the pack. Corporate and buy-side voters each chose the firm as the top corporate access provider overall, with Morgan Stanley earning recognition in 24 sectors covered by the buy-side survey, including 11 first-place finishes.

UBS came in second in the buy-side rankings, voted a leading firm in 21 sectors and winning best overall in five, including the Australia/New Zealand region and telecommunications industry.

Corporate voters, meanwhile, picked Credit Suisse for the second-place spot, giving the firm high marks for its investor conferences as well as for facilitating meetings between investors and executives.

The buy-side point of view was represented by more than 2,480 investors at 874 firms collectively overseeing $1.5 trillion in Asian ex-Japan equities. Voters ranked sell-side firms on their ability to coordinate meetings with executives, arrange site visits and factory tours, host investor conferences, and organize nondeal road shows. In addition, 193 corporates voted for sell-side firms and third-party providers on the same four attributes.
