Key insights
- An individual investor describes a concentrated day-trading strategy focused on a specific niche (solar inverters) that has yielded substantial gains. The investor expresses concern about sustainability and seeks advice on whether to hold or exit. The strategy's success is likely unsustainable and carries significant risk, but the limited scope and lack of specific company names makes the overall US market impact negligible.

So as the title said I've had about a 34% increase in my directly managed day-trading funds. I'm super new to this so just trying to diversify as best I can. My strategy has been to sort of delve into markets I know are growing and invest in the base companies. I.e. instead of just investing in a random solar company I instead invest in the company that makes all the inverters for solar panels across the board.
This has obviously served me really well thus far but I am worried that my luck will run out. Right now my plan is just to keep a close eye on things and keep making smaller trades to maximize my output. Is this a decent strategy? My gain thus far is WAY more than I had ever expected so I'm super pleased but also stressed that it's just a bubble of some sort.
Idk if I should hold and see what happens or dip out while I know that things are way up. Any advice would be great.
