<p>what's the difference between investment banking, business, finance, and finance research?</p>
<p>These are all sweeping generalizations, what you should do is go to wikipedia and dive into these areas more.</p>
<p>Finance is stocks and bonds.</p>
<p>Finance research is researching finance. (see above)</p>
<p>Investment banking is complex but it doesn't neccessarily have to do with "investing" people's money. You facilitate mergers and IPO's.</p>
<p>Business is anything where money is exchanged for goods & services.</p>
