Anyone have strategies for long term speculative investing that is not quarter to quarter following trends based on profits and behind the curve published economic analysis?

I am relatively new to working on a strategy that is not more safe and secure investing. I am not a numbers guy so I do not think I will ever become smarter than a hedge fund manager or be able to recognize things that are not market manipulations like pump and dumps.

I have a healthcare background so can understand some science. For the last year Ive been reading science related news and even subscribed to the journal Nature. Which is a great source for new science but I need to develop a disciplined approach to follow up with periodically looking for new companies and investments. Like these newly published studies sometimes do not even have venture capital lined up or google search results I could follow up on to look for new companies trying to become profitable. Which I assume is when some of you guys start paying attention to companies. I am not saying I will find the next Nvidia easily but it was figured out gpus could be used for AI years before Chatgpt triggered the AI bubble.

One of my first moves was to invest in the company Sana Biotechnology which had a successful development of a cell that produced insulin in one patient that did not trigger an autoimmune response. The issue is someone with lots of money doubled the stock before my purchase went through and I missed most of the stock price increase so far.

I know traditionally index funds and etfs were better for people like me but the US stock market with this K shaped economy is not traditional.

I can afford to lose money speculating and honestly I find it interesting learning what I have been learning so it has become a hobby almost. I do not want to go so far as to gamble on options. So this seems like a good niche for me to learn new science trends before they become popular and profitable.
