Mercury excels in 11th House if in a strong condition. Native has many friends and great number of contacts. On the bad side, 11th House also deals with Income.

In this case it would suit better to do a business although there would be some instability. Mercury with Mars in 11th house similarly gives instability and frictions with Boss or Customers who give the pay cheque. Mercury with Jupiter is somewhat better and there should be some stability owing to slow moving Jupiter. Mercury with Venus in 11th House would give financial irregularities and overspending.
