Most of my PR and professional contacts send Christmas cards, but for the past two years the boutique Wall Street firm, Rodman & Renshaw, has sent me heavy metal piggy banks. I assume the company sends them to its clients as well.
Last year it was an old-fashioned gas station attendant and this year it's a retro deep-sea diver with a treasure chest. I get the cute logic. Occasionally I interview R & R's senior biotech analyst Mike King and I often quote their research on this blog and on the air. There's no quid pro quo. That'd be unethical.
