Feel free to share here anything that you have developed and find it useful in your own investing regimen.
The assumption is anyone passionate enough develop something for himself - that saves time & drudgery (even a small excel), is a productivity enhancer and/or helps in analysis/dissection or systematic collation of information - can save others from re-inventing the wheel.
What we find useful, others may find much more useful - may even enhance/refine the original offering greatly. Often we have seen extra-ordinary results from such sharing.
A big Thank You of course to the contributors here!
