Watch some vids of Martin Shkreli doing discounted cash flow analysis. He doesn't use any fancy software he just starts with a blank excel sheet. Discounted cash flow analysis is not hard it just takes practice to learn all the steps. When you do a discounted cash flow you can determine if the stock is fairly priced or possibly undervalued. Underwriters and appraisers use this tool to determine the fair market value of companies and real estate.
Pick up a book on business valuation...there's literally a book called "business valuation for dummies" that is pretty decent.
Pick a few industries that you have personal interest in. For me, it has always been tech. One of my best performing stocks was AMD which I began investing in starting 2017 and held. When they released their Ryzen processors, they undercut Intel's prices while offering a product that performed just as good or better. That was an easy call.
There are a lot of opportunities in pharma and bio-tech, but I've found those often come out of nowhere and you have to read hundreds of clinical trials like martin shkreli did to find a good opportunity. I stay away from pharma and bio-tech myself. The industry is full of scam artists.
Some other plays that have done well are of course Carvana, which did very well after their debt restructuring, although they recently took a beating and I think there will be a major repricing before it goes up again. Palantir of course has done well now that Trump is in. I invested in Rumble bc I believe it is good to have a viable alternative to YouTube, but YouTube actually seems to have turned the dial down on censorship recently.
If you really wanna do some heavy research, do a deep dive into what's happening in Argentina. They are coming off a massive recession and Milei has been doing basically the exact same thing DOGE has been doing in the US. Elon pretty much copied his playbook. There is tremendous opportunity in Argentina as they are coming off the heels of a deep recession. If I were a real estate speculator I would be buying apartments in Buenos Aires. You can buy a sick pad in downtown for less than $150K rn. Stock wise MELI (Mercado Libre) has done very well. It is the equivalent to Latin America's Amazon.
