IMPORTANT!!! Never ever buy preferreds "at the market price". ALWAYS use LIMIT PRICE.
Preferreds do not have the trading volume like regular equities. Some people will issue a sell order through their broker at some crazy high price that just sits there unfilled waiting for some sucker. If you enter a buy order at market price and there are no other sell offers out there except for the crazy high price one, your order will be filled and you are screwed.
I've seen it happen were the latest market price was $25.00 but the next buyer bought at like $36.00.
