Stock market investing ideas

I figure that since this is a place I can record longer term ideas, and, that ideas I have regarding stock market investing don’t really have a good home, I can put them here.

Now really, I’m a fan of putting my notes about data near the data. So what I would really like, is inside my stock market portfolio management web page, that the vendor provide me with a small text field that I can update with a short note. But I don’t have that, so elsewhere, the information will have to reside.

On to the ideas:

  • 5G cellular towers
  • Neodymium miners (or processors)
  • Cancer immunotherapy / Biotechnology
  • Semiconductor technology
  • Surveillance technology

5G cellular

I think this technology has a huge growth potential. One of the trade-offs though, is that higher frequencies are required for higher bandwidth. Higher frequencies emit more power; but, electromagnetic power drops off with the cube of the distance (I think – it could be that the power drops off with the square of the distance). The upshot is that if the two antennas (sender and receiver) are going to be heard at the higher frequencies, they will need to be located closer together in physical space. So today, “good coverage” has one tower around three miles from the next tower (4G cellular).

With 5G cellular, the distance between towers will be 250 meters / 820 feet / .15 miles. The growth in towers (“base stations”) is going to go exponential (at least during the startup phase).

Perhaps it would be smarter to buy stock in the companies that make the transceivers (chips or whole power+chips+antenna). Problem is, I don’t know who these companies are.

But I like the idea of rent; that American Tower can make the initial investments, and the recoup their cost over the next nnn years. When I first heard of AMT, it was around $140 per share; today it’s at $168.
