yes but MSc Finance will give alot more grounding to those who are actually interested in finance. To be honest the reason i am doing it is to:
1) enjoy the experience+ network
2) get a shot at bulge bracket recruitment again.
3) everyone has a masters so it becomes more competitive to get onto top MBA programs, or good positions to do so.
4) many other things. + I always have my job to fall back on.
Basically if you can afford the money, you can't really go wrong taking 1 year after a 3 year undergraduate to complete masters. Afterall in America the study period is 4 years anyhow!!!.
