Guardian Market Thoughts on Market Making

A discussion that has gone forward for a few weeks in multiple forums has been "Market Making", or the effects of ineffective Market Making controls, most noticeable when much larger the normal sell transactions take place, often called "dumping".

Back in July of this year Guardian Market, SLR Chief Financial Officer, discussed the topic, and it's relation to Options Trading, on his blog Second Chaos, "the market value of securities is significantly more than the liquidation value (that is, if you sold all your shares as fast as you could) for almost every security, and even for modest amounts of shares."

"For example, take SLR, the company I'm CFO for. (This is in no way a critique of my shareholders, but if I'm going to pick on a company, I might as well hit home.) Suppose I owned 10,000 shares of SLR right now. The market price shown on CapEx is L$6,500. However, if I actually tried to sell all 10,000 shares, I would receive (after commission) L$5,153.02, which is 79.3% of the displayed price. Make it 50,000 shares and I would only receive 12.9% of my displayed market value!!! And we're not talking vast sums of money here - 50,000 SLR shares at market is worth about $120 USD. Enough to care, but not enough to break most of us financially."

"You can play this game with almost any stock on any market. There are exceptions, where management has taken care to set aside cash reserves to prevent this from happening, but by and large putting money into the market means you will need to take your time getting money out of the market."

"I've heard the idea of market makers being tossed around before. For those of you who don't know, a market maker is a person/firm that makes money off the bid-ask spread in the market. They provide liquidity. However, from my previous actuarial exam (which I passed, by the way!), Modeling Financial Economics, market makers need options in order to protect themselves. There are techniques whereby market makers can insure themselves against large price changes, or even set themselves up to make money if the market doesn't move. However, these require options, which no exchange in SL has been willing to set up yet."
