Parallel trading is an incredibly useful trading strategy.
Some parallel trades break can down and die.
When Parallel Trading Chain disappears, many more replace it.
One of the most fascinating things I learned when I first joined the equity trading desk at Morgan Stanley during the early 1980s was how to parallel trade.
A customer order would come in to buy a million shares of General Motors (NYSE:GM) and what did the in-house proprietary trading book do immediately? It loaded the boat with the shares of Ford Motors (NYSE:F).
"This is how you legally front run a customer," I was told.
Buy GM in front of a customer order, and you will find yourself in Sing Sing shortly.
Perhaps the client completed an exhaustive piece of research concluding that GM earnings were about to rise.
Or maybe a client old boy network picked up some valuable insider information.
GM doesn't do business in isolation. It has tens of thousands of parts suppliers for a start. While whatever is good for GM is good for America, it is GREAT for the auto industry.
So through buying F on the back of a GM might not only match the GM share performance, it might even exceed it.
This is known as a Primary Parallel Trade.
This understanding led me on a lifelong quest to understand Cross Asset Class Correlations, which continues to this day.
Whenever you buy one thing, you buy another related thing as well, which might do considerably better.
I eventually made friends with a senior trader at Salomon Brothers while they were attempting to recruit me to run their Japanese desk.
I asked if this kind of legal front running happened on their desk.
"Absolutely," he responded. But he then took Cross Asset Class Correlations to a whole new level for me.
Not only did Salomon's buy F in that situation, they also bought palladium (PALL).
I was puzzled. Why palladium?
Lots of car sales, which the GM buying implied, ALSO meant lots of palladium buying.
And here's the sweetener.
Palladium trading is relatively illiquid.
Because palladium is the principal metal used in catalytic converters, which remove toxic emissions from car exhaust, and have been required for every U.S. manufactured car since 1975.
So, if you catch a surge in the price of this white metal, you would earn a multiple of what you would make on your parallel F trade.
This is known in the trade as a Secondary Parallel Trade.
A few months later, Morgan Stanley sent me to an investment conference to represent the firm.
I was having lunch with a trader at Goldman Sachs (GS) who would later become a famous hedge fund manager and asked him about the GM-F-PALL trade.
He said I would be an IDIOT not to take advantage of such correlations. Then he one-upped me.
He answered "Absolutely," as was his way.
But the first thing he always did when searching for Quaternary Parallel Trades would be to buy the country ETF for the world's largest supplier of the commodity in question.
Since then, I have discovered hundreds of what I can Parallel Trading Chains, and have been actively making money off of them. So have you, you just haven't realized it yet.
I could go on and on.
Do this for decades as I have and you learn that some parallel trades break down and die. The cross relationships no longer function.
The best example I can think of is the photography/silver connection. When the photography business was booming, silver prices rose smartly.
Digital photography wiped out this trade, and silver-based film development is still only used by a handful of professionals and hobbyists.
Oh, and Eastman Kodak (KODK) went bankrupt in 2012.
However, it seems that whenever one Parallel Trading Chain disappears, many more replace it.
You could build chains a mile long simply based on how well Apple (AAPL) is doing.
Suffice it to say that parallel trading is an incredibly useful trading strategy. Ignore it at your peril.
