Financial markets have fascinated me since childhood. I strive to combine my education in biology, math and history with common sense to find winning trades. To identify good investments and the right time to enter/exit them, I draw on all financial disciplines that could be helpful. The following is a non-exhaustive list that inform my decisions: Finances of a company, market condition, who owns it, what insiders are doing, analysis of trading behavior, option positions, short interest, public perception, social media, retail involvement, deep valuation of assets and patents, debts and obligations etc. Btw, my screen name refers to the popular MODIS satellite package in polar orbit around earth. It's mission is to daily photograph the entire planet in several optical bands. This data that is then made available to researchers like biologists, which is how I know about it. It is my inspiration to try see things as they really are. MODIS also reminds me of my favorite quote from Mr. Buffett: "It's easier to make up a lost opportunity, than to recover from a loss." The instrument moves on, seeing new things; it doesn't get stuck. Capital is a precious resource, so every trade deserves to be as perfect as you can make it.
