None of this stuff is special. Once again, I will say the hot sectors aren't commodities, which is essentially what home schooling and its spin-off industries are. Just like home building is at all time highs right now, but no one is getting rich buying their stocks. To answer this question you need to be looking at proprietary items that can give a company a significant edge, whether it be through patent protection or just superior thinking in products that can't be easily replaced or replicated. The best candidates are for something tech related, something medicinal, or something very specialized in services. If its a sector with 20 competitors and all offer essentially the same product or service, you won't hit home runs. Granted there might be some nice profits for all involved, nice steady profits, but it won't be a home run sector.
