BoAML read as B O A M L?

If you mean read aloud, as a radio/TV/youtube broadcaster would do, then no.

It would be read aloud as
"...wrote Lu Ting and three other Bank of America Merrill Lynch researchers in the report."

~~ One proviso: there are many abbreviations which have become part of the spoken English. For example, here in New York City, no reporter would say "The Long Island Railroad" throughout a news-piece. They would say it once in their lead paragraph "Long Island Railroad officials announced today...blah, blah blah." but after that, they would say LIRR (pronounced el-eye-are-are) anytime they were referring to the company.

Abbreviations or acronyms are tricky things. As a writer or reporter, you have to use some common sense when using them instead of the full name of the company, the law, the office or even the person that they stand for. They have to be in common usage, they have to be immediately recognizable to either a reader or a listener.

Many times people inside an industry will speak in acronyms that they use on a daily basis, but when they attempt to speak to a broader audience, they find themselves constantly having to stop and repeat what the acronym stands for in order to make themselves understood.

I was listening to a radio interview a few days ago about the US Supreme Court and the interviewer had to stop the speaker several times because he was referring to "AMDA" (Americans with Disabilities Act) in two different ways. Sometimes he said "A-em-dee-A" and sometimes he said "AM-Dah".

HE knew what he was taking about, the rest of us were only hearing jargon.

Note: BoAML is not currently a commonly spoken acronym.
