Last summer I had to take down a large Birch tree that had died from infestation of Bronze Birch Borers. The tree overhung the site where I was preparing to build a shed and I decided to remove it first to prevent damaging my new creation.
Upon climbing the tree in preparation for its removal I found myself reflecting on trading metaphors. There are tremendous risks in being high in a tree with a powerful chainsaw.
When one gets very high in the branches of a tree one finds it is critical to take the effects of the prevailing wind into account before doing anything. The wind can determine which part of the tree to remove first and where to drop the debris.
I think about safety first and at all times during the operation. I wear a climbing harness and attach myself to the trunk of the tree in two places with two separate lines. I pay close attention to where I place my feet and hands.
Familiarize yourself with the tree. Is it recently dead or has it been for some time? Can it be climbed safely or should it be taken down from below or from a cherry picker? A recently green tree will support large weights on a one inch diameter branch, a dry or rotten tree will do no such thing. Can you drop branches safely or are you too close to the house? Sometimes each piece has to be secured prior to cutting and lowered carefully with a line.
Use a ladder to get into the tree. Tie the ladder off to the tree in a way that prevents it from wobbling or rotating. In markets, sometimes one must stand on others shoulders to get oneself in place.
Have the necessary tools with you before you climb. It is time and energy consuming to have to go back for them. And not having the proper tool can induce you to use the wrong one rather than go all the way down and back to do it right.
Be familiar with your tools and know how to use them and care for them. Powerful tools, like leverage, allow you to do big jobs quickly but they bring powerful risks. It is amazing the number of ways a chainsaw can ruin your day. Chainsaws can bounce back out of the cut right at you so it is important to keep your face and body off to one side when cutting. Chains can break and fly back as well and fly or wrap in entirely unexpected directions. Be aware of the damage that your tools can do to you, not just the tree. Pay attention to them and treat them with the respect they deserve. Try to make allowances for the unpredicted. I've seen a chain fly off the saw and become entangled around the large branch it just removed and very nearly pull the user out of the tree.
Secure heavy tools to you or to the tree with a line strong enough to hoist them but light enough to part if the tool becomes ensnared in falling debris.
Never start using a heavy power tool until you have secure footing. I usually rest my weight into the harness and let my lifelines support me, using my feet to keep me stable.
Take your time. Being rushed will get you hurt.
Never bite off more than you can chew. When removing large portions of the tree with a single cut, they can behave in unpredictable ways, such as twisting or bouncing the tree or grabbing your lifeline and pulling it down with them. Once a very heavy piece begins to fall, there is absolutely nothing you can do to stop it.
Never extend your reach beyond what is comfortable. Using a tool at more than arms length puts you in a position that prevents you from reacting quickly if something goes wrong. It puts undue stress on you and the tool. It removes whatever leverage you have on the tool. It also prevents you from "feeling" properly through the tool. When using a power tool you receive signals about the material you are cutting and the nature of the stresses on that material. You can always tell when a branch is about to go if you are listening carefully to the tool. That feedback is denegrated by reaching too far or by using only one hand.
Several years ago a friend was cutting off a tremendous horizontal limb from a large oak. He was on a ladder extended to its maximum height and leaned up against the limb. The ladder was resting on the limb between the trunk and the cut and as the limb came off, this stub end jumped up and the ladder fell away beneath it. My friend tossed the saw and grabbed the three foot thick trunk and tried to hold on but slid down and finally fell off, shattering his femur and tearing up his chest and the insides of his arms. Had he and the ladder been secured to the tree he probably would not have fallen.
What have I missed?
Scott Brooks adds:
Hunting is considered by many to be a dangerous activity, what with a bunch of guys running around with shotguns or rifles. However, there are very few actual injuries from shooting accidents. The main cause of accidents are not the inanimate objects that send forth projectiles, but another inanimate object…tree stands.
Every year, people who feel that they are immune from the laws of gravity climb into stands and sit or stand waiting for their prey to wander by. And every year there are people who are stunned to find out that the laws of gravity are much more brutal and punishing than they thought.
There are only two types of tree stand hunters: Those that have fallen and those that haven't fallen yet. No matter how much you think you'll be able to hang on, or how adept your dexterity, you simply can't react fast enough to ward off an accident or mechanical failure.
I can personally attest to the feeling of bile rising in my throat from the fear of lost balance while perched 15 up in the air…and that was when I was wearing a safety strap.
I have a standing rule on my land. If you climb up into a tree stand, you must not only wear a safety strap, but it must be the first thing you put on when you get into the stand, and the last thing you take off when you climb down. I have asked (told) people to leave my farm because I caught them up in a tree without a safety strap.
So why even climb a tree stand if it has that much risk? It's about risk vs. return. I love the return I get from arrowing a nice buck. Same is true with trading. I love it when I get a great return for my clients. But the reality is that it's important to wear a safety strap when trading. Just as I profited in my poker playing days by taking a slow grind it out approach (never going all in), I do the same with trading. I'm satisfied with the inferior returns of a non-leveraged portfolio. My theory is that the more you leverage, the higher you're climbing and the thinner your safety strap gets.
All of my bad losses and sleepless nights have come from leveraging or taking too much risk.
That's why I'm a pretty boring guy these days.
Jim Sogi comments:
Professional tree trimmers all use a belay. Mountain climbers also belay themselves for protection or to 'hedge' their position in case of a fall.

Never lend your chainsaw to someone who doesn't use them much. As in don't give stock advice to people or just give them advice that is general in nature–this saves on friends. Always remember torque and twist. If you don't read and predict how the cut will behave, rethink it. I have seen trees twist and pull the wrong direction, seen limbs bind back on the saw and have trees fall off course because of hidden dead spots. Be ready for the twist of the market as it takes your trade and bends it slightly the wrong way. Once I saw a dead tree being taken down by a friend. This large straight tree as it was falling broke apart into 3 huge sections. The trunk part closest to the ground went the right way and the other two in tangents like a V. Market wise–don't mess around with a junk-trade–its just not worth it and you can get hurt. And lastly don't drink beer before operating a chainsaw, nor chop wood with only shorts on, or put your hot saw down in a pile of dead leaves.

Ok, this is a little bit like what I have been doing the past 2 years–namely Health and Safety oversight for pipeline and tank construction workers… guess who the least favorite person on the jobsite is?
There are probably better business analogies than below but here it goes (this is the short list! and not complete by any means, OSHA website would be a good resource):
1. I would have a health and safety plan in place with contact numbers and how to get to the hospital. Is there a written plan of action for each step of the process with the risks involved and the ways to mitigate the risk. (Investment plan)
2. Use a "buddy system". Have a friend nearby that can help you in case of an emergency. Have a 1st Aid Kit and someone Red Cross trained in 1st Aid and CPR. (Mentors and advice of others)
3. Survey the tree to make sure there are no hazards you have missed. Electrical lines. Red ants. Poisonous plants. etc. Ask yourself what is the worse thing that could happen (What could go wrong with your investment? What could come back to bite you?)
4. Inspect your equipment. Is your climbing harness worn anywhere? Are the lanyards of the proper length? (Guys have died or hurt themselves badly by not having the proper length on the lanyard, yeah they had their fall protection on it just didn't stop them in time from hitting the ground). Is the ladder rated for your weight? Do you have a GFCI if you are using an electric chan saw? Do you have cut resistant gloves? Do you have on hearing and eye protection? Level D OSHA clothes?
5. If it is hot or cold you need to take a break. Drink water. If you get tired you are more likely to make a mistake. (Take regular breaks from the computer screen)
6. Do you have enough light? Night time operations are doubly dangerous for workers. You need visibility. (Transparency in your investments)
7. Have you set up for disposing of the branches and such. You don't want the city to fine you unnecessarily for yard trash. (Tax consequences)
8. Wouldn't it be cheaper given the risks to have a professional service do it? (ETFs/mutual funds vs. individual management)
9. Are you sure the tree won't fall on someone else's property or their fence? (What are the liability issues?)
10. If I do get hurt what will the effects be to my family and others? Do I have the skills, knowledge, and physical abilities necessary to do the job right and do I understand the risks? Am I in a good state of mind and able to stay calm and not get angry if something doesn't work out right? Do I have a fear of heights?
We always carry a card around in the wallet for safety reference and it sort of boils down to 3 steps: 1) Assess; 2) Analyze; and then 3) Act.
It sounds like overkill but an effective safety "culture" within companies has been shown to dramatically reduce injuries, deaths and all sorts of economic and emotional costs. And it is a good idea to teach everyone at home how to stay safe too. If you do not have a sense of vulnerability then you are susceptible to hurting yourself or others around you.
Russ Sears comments:
In the last four years I took down three cedar trees that were dying. Here are a few things I did that were missing from the lists above.
1. Limit the access to the area. Shut down the drive-way, no extra people or kids allowed etc. Tree cutting is not a spectator sport. The trading room is sacred. No extra people or kids. Never show off.
2. Notify the neighbors when near their property. Likewise no kids. They let me know if they would be outside etc. I worked around their schedule. When working with others money, its all about them, not you.
3. Call the buried cable hot-line to have it marked before. Know the hidden risks and try to avoid them.
4. Have lots of rope. Extra rope tied to the tree and other trees can help prevent the tree from going the wrong way onto the house. Controlled slack on a large trade is a must.
5. Keep the area clean, limbs dragged away as they are cut. You never know when you may need that exit.
6. Rent what you do not have, but get the right size saw above all. It may cost more, but do it right.
7. Have patience. Take it in small pieces. It is only impressive in the vast woods when it all comes down at once. In your yard it will only be damage. Know your size. And do not try to meet a schedule. Pay that extra day's rent, Leave the stump up till next weekend. Do not try to swing for the fences to meet some arbitrary goal.

All valuable advice in this tree thread! Not to say it's missing, but I often add an iron chain as a line (with mountain climbing equipment).
Among dangerous things a falling tree is able to do, having the foliage act like a spring is a rather vicious one. The tree falls nicely with its big round green foliage, everything seems OK, but the green foliage is slowly compressed/crushed (for 2 or 3 seconds) and then the compressed unbroken foliage uncompresses and moves the 3 ton trunk in whichever direction. If you're in the way you're killed without even noticing it. (Certainly a market analogy here!)Folded branches are also a very classic cause of injures.
Many things can happen when cutting trees– unexpected things, so as a general rule, better be largely too cautious then slightly too incautious. Even if other people do not understand, you are in the tree with the chainsaw, not them.
