Alex999, I disagree with your comment, "Old saying that stock trading is a mechanism for transferring wealth from impatient to patient has some truth in case of MUN."
The simple fact is the "patient" in MUN have lost over 90% of the value of their investment as MUN has declined from over $1.00 to a few cents.
Care to tell us at what price investors were meant to become "patient" MUN investors? $1.00? 90 cents? 50 cents? 40 cents?
