On my yahoo forum which is free for anyone to join one member set up a naked puts trade on Cummins Stock which trades under the symbol CMI yesterday. This trade was done based on a formula devised around the Greeks which tries to estimate what chances there are for the trade to be successful simply by the stock staying above the put strike sold. By selling the put strike at $105, the goal is to earn the put option premium by having the stock stay above the $105 valuation. This morning though the stock collapsed to $100.61 on disappointing earnings.

The Greeks Estimate

By using the Greeks, the technical stats showed that there was a 90.6% chance the stock would remain above the $105 put strike for the next 12 days. But the Greeks cannot take into account short-term volatility. They look at past movement and price action to predict future movements.

Today however Cummins Inc net income fell to $380 million from $423 million in the third quarter results announced today. Estimates were for earnings of $2.59 per share but instead they came in at $2.14.

The forward guidance was also poor with Cummins announcing 2000 job cuts by the end of the year. Basically revenue out of Brazil and China dropped dramatically and the outlook remains poor for diesel engine demands through 2016.

Volume Defeats Greeks

While the Greeks certainly have their place especially in option trading, stocks that have been in a decline such as Cummins Inc are often better traded by reviewing volume to determine where the strongest support is and then setting up trades around those support points.

This is because in any decline stocks normally follow patterns and when they reach strong support levels where large quantities of shares have traded, they slow their descent and often will bounce back or at least stabilize and not fall further.

To study volume in a stock I use the 5 year chart and look for periods when volume was above average. This advises me where larger quantities of stock has been traded and where often the majority of longer-term investors are sitting with positions.

Cummins Inc Stock Chart – 5 Year

To accomplish this I review the average daily trading volume which in CMI Stock is 2.1 million shares. I then draw a dividing line through volume at 2.1 million (light blue line in chart below) and look for above average volume periods (marked in blue circles). You can see there were five very strong periods in 2011 and again in 2012 in the chart below.

During those periods the stock traded large volumes daily within two ranges; $95 to $102 and  the $85 to $95 valuations. That tells me that if the stock cannot regain its footing after today’s sell-off the stock could fall back to those levels. A break below the $85 to $95 valuations is almost always brutal for investors as this would result in many long-term investors bailing on the stock.

Rescuing Trades

Technically looking at a stock through volume rather than using the Greeks provides a huge benefit for investors such as myself who like to sell put options at or below support points for income but rarely want to hold stock for any longer than a few weeks at most. The Greeks are best used for very short periods of time but they cannot accommodate earnings periods and those periods of high volatility such as we saw at the end of August this year.

Volume Is Absolute

Volume on the other hand is absolute. When the trading day ends, volume terminates and is recorded. Volume then is by every measure a better indicator for understanding how far a stock might fall and where to consider getting interested in a stock for income trading and potential stock trades.

Protecting Capital Is More Important Than Profits

Protecting capital from loss is more important than the profit it can earn. It takes longer to recover losses than to make a profit. Capital that is lost no longer compounds and cannot grow my portfolio.

Understanding The Risk To Capital When Selling Options For Income

When I sell options it is often for small amounts of income. For example in this case the investor sold the $105 naked puts for 55 cents. To close that put option this morning (Oct 27) the cost would be $5.00 for a loss of 809%.
When selling options whether puts or calls,  this often does happen. Time must then be spent trying to recover the capital that was lost. During the recovery period there is no growth in the portfolio and no compounding of returns. Weeks of recovery work can often turn into months.

Understanding Volume’s Importance

Understanding volume rather than the Greeks can go a long way to assisting an investor in protecting his capital when selling or trading within any stock, but it is particularly useful when a stock such as Cummins Stock is already in a long-term decline.
