What is the Securities Act of 1933?Is it the same as the SEC?

Yes, it is pretty much the same thing.  This law was meant to regulate the sale of securities (stocks, etc).  The point of it was to try to protect investors from fraud.

This law had two main goals.  First, it was supposed to make sure that the public (potential investors) got legitimate information about securities that were being offered for sale to the public.  The second goal was to prohibit sellers from deceiving or defrauding the public when they sold securities.

The SEC itself was not created until the next year, but the 1933 law gave the government the right to do much of what the SEC does.
