HSR far better than supporting bankrupt and expensive airports and electric vehicles with $1T market cap.
Electric vehicle have to follow the traffic rules and cannot go faster from Point A to Point B. Tesla tires will burn down due to heat at sustain speeds above 150mph.
Imagine going to Ski in Lake Tahoe form Monterey/Caramel/ in One Hour. No need to stay at night.
Even Denver/Aspen Colorado Day trips will open up.
Day trips to Seattle and LA will become possible for large number of people. No need to go hours ahead of time to Airport and all centralized loading and unloading of airplanes. as in Train every person carry there own luggage. have you waited for your luggage at airport?
Its the whole system and technology that transform the world. Cost will go down automatically when networks and grids created. and all the subsidies from airplane manufacturer are removed. Boeing already eaten Trillions and still need hundreds of billions of imported parts and personal.
Coming back to NVDA, FA matters…Here is the major pull force for NVDA. It is taking over arm at $46 Billion, which is a game changer for its growth. The giants are against its take-over !
However, it was halted by objections, stocks are getting down to the lowest. At some point of time, when ARM+NVDA is approved, stock will jump like the way you stated doubling its value.
By 2030, The Accelerator Should Replace The CPU As The Main Server Compute Engine
Accelerators, such as GPUs, Tensor Processing Units (TPUs), and field programmable gate arrays (FPGAs), perform the most demanding computing tasks including artificial intelligence (AI), analytics, drug discovery, and cloud gaming.
Nvidia is the king of GPU. AMD is buying Xilinx, the leading FPGA vendor.
It is widely understood. Any one building Apple car comes in collision course with EU.
Neither TSMC nor Samsung will invest in US unless they commit to similar investment in Europe.
An article dated Nov 10 2020, on your favorite semi stock. Author used a combo of FA + EW to explain the price behavior. He felt short-term direction is likely down (so far price goes sideways), he gave a worse case scenario as low as $238 IMHO, worse case should be 200-day SMA. However, he thinks can go to $735-$800 in a few years (not a few weeks as suggested by some millennial youtubers).
Since you have tons of NVDA, and you ask WHEN the market would peak!
Short answer: I am not sure.
Long answer: May be already here…
Look at the QQQ chart below, you would notice there is a bearish divergence since Sep last year. And volume has been declining which mean investors have been pulling out money from stocks in QQQ. QQQ could dive anytime now, the longer we stay in the QQQ, the more risky it will be. My chart shows the most optimistic count, the bearish count is QQQ has already peaked.
Refer to the 2nd chart on NVDA, scary? My computation indicates (III).V.5 might have been completed at ~$615 last week. However, there is an optimistic count that lead to $730s. We will know after NVDA earning 2mrw. To err on the safe side, I have liquidated the entire semi portfolio ~$300k except for 100 NVDA shares i.e. about 20% invested, 80% cash. I will miss out a lot of upside if it rockets to $730s but what if… I believe after hitting $730s (should that play out), NVDA would come back to today price, I will scoop up then. If it tumbles from here, I can go all-in to this super duper buy n hold (no need to trade) when it bottoms.
Didn’t add to NVDA. Semi portfolio remains 100 NVDA (20%, less now) and 80% cash. Waiting for the BIG crash!!! Prefer to leave the account mostly cash and wait patiently for market to crest and then crater. 18 months? So wait 18 months.
I show @manch a similar chart few days ago, somehow is not in this thread. Might still be in wave 4 (best case), worse case is completed wave 5, so… hodl onto to 100 NVDA and see what NVDA reports after hrs. Keep cash in this account to do a fight back if other accounts are decimated.
I went max 90% full cash yesterday and bought only small 10% on margin today ! Took pledge next time I do not perfectly (every time I fail !!). Next week, I need to release margin…
