@themotleyfool behind the video scenes guy. Follow me at ProShopGuy on MF. I use this platform as an electronic sharing space with things I find interesting.

@307Fool I was not so smart. I wanted bragging rights to be able claim I purchased SNOW on IPO day.
It is a learning experience as I learned about how IPOs get priced on IPO day.
Tim Beyers told MF members it should be valued at $140. I bought in at over $210.

I purchases NVDA three times. Once in 2015 and twice in 2019.
I have trimmed NVDA ten times over the last decade.
After the ChatGPT moment, I made the decision to ride the AI wave as I had enough conviction in what Jensen Huang was selling.

I found the secret to investing. LOL
Since 4% of all publicly traded companies produce all of the generated market cap, find at least one quality compounder that you can hold for a minimum of ten years. And if you find it, let it run regardless of portfolio allocation.
Found mine

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

@drowsyinvestor I started a position in NVDA in 2015 and I have trimmed 10 times in the last decade. However, since it is a 60 bagger for me it has grown from an 4% position to a 30% position.
As the position has grown you learn the stair step fashion the market values the stock.

@dougboneparth So much easier for a Baby Boomer who entered the work force in the 70s. Still had a formal dress code and a book that was the bible.

@bleekertech At some point, zooming out and getting your perspective/mental model on the diffusion of AI and its value capture as the technology matures.
The AI frontier model builders are driving CAPEX now but does it level off or decrease as use cases emerge higher up the stack?

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

Like a frog in a warming pot of water, we tend to forget how much technology we have surrounding us.
The internet was the first wave, then came mobile and then cloud computing.
The next wave is AI. Rather than focus on what could go wrong, think of the positives of the last waves

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

@JimPGillies BTW we did not "invest" (as I always considered myself as a saver during my business career) until I was 60.
As luck would have it, I was able to find Nvidia thanks to a MF video featuring @bleekertech
The rest is history as NVDA is now over 30% of our portfolio.

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

@JimPGillies We started when I was 30 and stopped when our company did not survive the GFC. So only 25 years of DCAs through Black Monday and Dot Com crash.
Emerged at 55 with a portfolio roughly 60% of my lifetime earnings.
15 years thanks to a booming 2010/20 market now 4X lifetime earnings

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

When a technology hits a learning curve and demand explodes, producing that familiar hockey stick, analysts often stay stuck with their old assumptions.
And like smart sound skeptics who acknowledge that AI cannot defy gravity, I acknowledge anything is possible.

@SemiAnalysis_ free email newsletter is a treasure trove of resources for everything from semiconductors to understanding GDP measurement.
If you want to update your mental models about how the world will change as AI diffuses, I highly recommend subscribing to their Substack.

When you start investing stay humble about what you think makes the world go round.

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

Markets are information-processing systems. Prices aggregate millions of individual observations into signals.
AI increases the capability and capacity of information-processing systems.
AI potentially makes intelligence abundant.
Who can generate the best predictions?

My Top Ten Holdings: 5/29/26 no indexes NVDA (29%) (2015) AAPL (5%) (2017) GOOGL (4%) (2019) PL (4%) (2021) SHOP (3%) (2017) AMZN (2.36%) (2019) CRWD (2.13%) (2020) MSFT (1.97%) (2019) MU (1.77%) (2024)

The real question is what were the Polymarket odds on the baby. Might have been some insider trading.

It was supposed to be a serious competition, but...

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

@JRogrow If you do not have failures you have over engineered your solution. Elon showed the way.

@307Fool When you build a spray and pray VC picks in 2020/21 totaling over 100+ positions your daily winners can look weird.
The percentage gainers do not matter unless you have position sized accordingly.

As I navigate my way through my career and ended up with a sizable 401K, I began investing in later 50s with technology front and center as a result of this book and its laws.

[ProShopGuyMF (Mike McMahon) @ProShopGuyMF1]

Many books changed mindset.
Personally reading The Seven Habits of Highly Effective People and Awaken the Giant Within were foundational.
While I never considered myself an investor, the 1990 book Unlimited Wealth was inspirational in viewing how the world would evolve.

The COVID shock of 2020 forced a number of companies to evaluate their ability to deal with external forces. As a result, they changed their operating processes to respond faster. As a result, we are showing rising profit margins across the board.
Now AI enters the picture.
