You can break debt out into a few parts to understand it better. With bonds, you want to see how much they’ve financed, the rates, and when they are due to pay back on those bonds. It could be a very small amount or many, either way, you want to see how that fits into the debt picture. Secondly, you could look at notes with lenders to see when those expire or how much the monthly payments are. This would include lines of credit, as they are similar but have their slight differences. Lastly, any short term debt should be noted because that should be going away within a year. What you do not want to see if a chain of long term debt being used to pay short term debt, which could be a vicious cycle that is indicating a cash flow issue.
Debt does not play into technical analysis much, but it could still be a factor non the less. Be sure to fully understand the intention of each debt because if it is being used to expand or grow the business, look at it as an investment because that will likely return more to you. Besides that, use common sense and if the debt pattern seems fishy, it probably is. Debt can be a powerful leveraging tool in business, but if used incorrectly, could bring a business down. There are many ratios to use as well if you are looking to compare across an industry so be sure to pay close attention to those. If you still have questions, reach out to an investing community and ask for peer input, as that can help to guide your thought process.
