Also Master's should have an apostrophe. The 2nd sentence is not punctuated correctly. Put either a period (.) or a semi-colon (;) after "exhibition". "Trend" should probably be plural, "trends", because there is usually more than one trend going on at a time.

It's a bit technical, although I'm assuming that's due to the target audience you're aiming for. One issue is in this bit "and continue to increase their value of wealth." I think it's ok grammatically, but it doesn't sound natural. A better way to put it would be something like "and continue to learn ways to increase their wealth".

Guest speakers, invited every year, give helpful advise to investors on how they can gauge the investment climate and make clear investment choices with a view to increasing their overall net wealth. During the exhibition, there are some forums and finance lectures held specifically for advanced investors, who show their great interest by turning up in numbers so as to learn more about market trends and the financial options available.
