lt cap,

Thanks for bringing attention to the Barron's article. From what I understand of it, given my non-IT mind, I would take a flyer on it, given my belief that the cybersecurity sector can do nothing but grow with each new break-in. I'm not sure there's a way to tell when/if it will have an IPO, or if it will remain private or bought-out by  a larger company. A call to them might answer that. I played PANW a while back for a small profit. But concluded that the rich PEs in the sector reflected assumptions of future growth, rather than current performance. If this new company has a completely new, and more effective, means to block cyber-attacks, yeah, I'll bet some money on that.

Read this article about 5G and CES. It does look like 'real' rollout is likely a 2019-2020 event, I think:

I believe there might still be 10% upside to the market, given Trump's gifts in tax reductions and destruction of any oversight or regulation to businesses. Towards that end, I had taken some $ off the table, and re-deployed only a part of it as of last last week into Berkshire B, SPY, and ROBO. ROBO is an etf that tracks 10 firms engaged in robots and AI deployments. It includes one sea-drilling service company that I don't like, but decided to take a shot with it anyway. So far, all 3 are positive by a bit. Some time ago I put some funds into NVDA and ISRG. They both immediately tanked after doing nothing but skyrocketing for the last year or two. After correcting about 10%, NVDA is back at all-time highs, and in the black. I believe they have so many opportunities in so many areas, such as AI autos, that they will continue to flourish, given their ability to execute on their chip-making. ISRG I'm less confident about - there are other AI surgical companies and products in development, but they won't actually hit the market for a while. I consider ISRG's prospects less solid than NVDA's, but that's partly based on my knowing NVDA a good deal better.

When this market falls apart, I think it will be pretty dramatic. The Trump tax and industry policies are what I think will drive things in the short term, but I'm not sure they'll actually have a large lasting effect - being able to dump mining waste into rivers without regulations is the kind of thing that may help boost profits short-term, but it seems to me a little bit like selling your birthright for a bowl of porridge. I see many economists (Krugman, Samuelson) backing away from making predictions about when something will 'go wrong'. Only that when it does, the longer this market inflation valuation goes on, the harder the landing will be.  I was surprised to learn that we're still only the 3rd longest expansion in history. I would've thought we were the longest.
