I don't invest much directly in stocks, just playing-around money, because I don't know or care anything about trading stocks. I do no analysis, don't check the metrics, don't even really know what they are. I just stick a few bucks on companies whose products seem solid and forward-looking to me, which is why I bought Tesla years ago (hehe).
When I started researching electric motorcycles, I ran across Sevcon's name, and looked them up. Honestly, it wasn't their electric motorcycle business that impressed me, that's real and probably going to grow, but still a pretty small niche. But they're primarily a one-stop shop for industrial electrical equipment like pallet jacks, forklifts, etc., and that's already a very solid business with nowhere to go but up. Tesla's gigafactory alone is probably going to buy about a bazillion pallet jacks as they gear up. So far, Sevcon's been even better for me than Tesla has been. Knock on wood that it will continue.
