He will also likely widen his spread, say to $2-$2.50. This is because he is unlikely to want to lock in a loss on his sales by raising his bid above those sale prices, though bid prices will rise when a disciplined market maker will ultimately acknowledges when it is safer to lock in a loss than to ride a bad position.<\/p>\n\n\n\n<p>A market maker\u2019s defenses are relatively limited.&nbsp; They are generally some combination of:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>Hedge<\/li><li>Widen spreads<\/li><li>Reduce sizes<\/li><\/ol>\n\n\n\n<p>If it becomes difficult to professionals to hedge, as we saw in August on the upside and in March on the downside, they have to widen their quotes and shrink their posted sizes. &nbsp;&nbsp;This is why liquidity can dry up in volatile markets, <a href=\"\/campus\/traders-insight\/securities\/options\/liquidity-considerations-in-a-down-market\/\">as I alluded to in this video recorded during late February\u2019s chaos<\/a>.&nbsp; And remember, it\u2019s common to think only of delta hedging (with stock and other options), but the market maker needs to hedge several other risks as well, such as volatility, decay, and others (aka \u201cAll the Greeks\u201d, since those exposures are referred to by Greek letters). So if there is excessive demand &#8211; either from retail or institutions \u2013 market makers have no choice but to raise prices quickly and aggressively.<\/p>\n\n\n\n<p>Bear in mind that many new investors moved to investing from sports gambling. The risk\/reward on options is similar to that on sports betting. &nbsp;In both you wager your entire outlay on a leveraged outcome. &nbsp;Yet brokerage firms charge a smaller fee (low or zero commissions) than a bookie charges (his \u201cvig\u201d).&nbsp; Markets also present innumerable events on which to speculate. &nbsp;And lately a new dynamic has shifted the odds in favor of the speculators: it is possible for enough options speculators to improve the chances for them to receive their desired outcome.<\/p>\n\n\n\n<p>You may wonder how this is possible.&nbsp; It is directly related to the hedging activity undertaken by market makers.&nbsp; Unless a match is fixed, the amount of betting on a sporting event has no impact upon the outcome. &nbsp;The odds will shift if enough action comes on one side of a football game (as in the market-making example earlier), but in theory those odds have no impact on which team will win. &nbsp;In options, if there is such an extreme imbalance in the action, the hedgers will be forced to push prices in favor of the initial buyers.&nbsp; Momentum traders see the price action, and join in the buying, pushing prices ever higher.<\/p>\n\n\n\n<p>Ever higher until it stops, that it.&nbsp; Every trade reaches a point where it gets so crowded that it naturally runs out of fresh buyers at higher prices.&nbsp; That is what we saw over the past couple of weeks.&nbsp; The most popular trades simply ran out of steam and the changed demand dynamic forced a quick readjustment of prices.&nbsp; The lesson for speculator is the same as it is for bettors \u2013 if the odds become extremely unfavorable, it is probably best to avoid that bet.&nbsp; Options traders need to recognize when the odds are against them.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Seemingly at once, retail investors became enamored with call options on highflying technology stocks.
