With regard to investing in quantum computing, what would you recommend for a 20-year-old investor with minimal experience in investing?
From ChatGPT:
Excellent — you’re looking at this exactly right: for a 20-year-old new investor, quantum computing can be fascinating but high risk. Let me quickly frame this for you:
Quantum Computing: High-Risk, Long-Horizon Play
At age 20, you have the biggest asset: time. Quantum computing may take 10–20 years to fully mature commercially. So, a small speculative allocation might make sense alongside a core portfolio.
Here’s a simplified way to look at the most “investable” companies for a new investor:
My advice for a 20-year-old investor:
-
Core first: (80%)
Build your portfolio mostly around index funds (e.g., S&P 500 ETFs like VOO or SPY).
-
Speculative sleeve: (15%)
Consider allocating ~1-5% to high-risk speculative plays like IonQ or Rigetti.
Big Tech with quantum exposure: MSFT, GOOGL, IBM (10%)
Pure Quantum Plays: IONQ, RGTI (5%) -
Diversify your quantum exposure:
You’re already getting indirect exposure through companies like Microsoft, Google, and IBM.

Stay informed:
Follow quantum tech news — things change fast here.

Don’t FOMO into hype cycles:
Quantum stocks can swing wildly based on press releases and investor sentiment.
ChatGPT will build three investment strategies:
- Core (80%): see above
- Sleeve (15%): see above
- Moonshot (5%): see below.
Moonshot, quick example:
Let’s say you start with $5,000:
-
$2,500 — VTI (US stock index)
-
$1,000 — VXUS (international index)
-
$500 — BND (bonds or cash equivalent)
-
$500 — MSFT + GOOGL + IBM (big tech)
-
$250 — IONQ
- $250 — ARKQ or similar
From my perspective: the BND (bonds or cash equivalent) does nothing for the portfolio; the analyst is simply investing using "old school" percentages. If the $500 is simply a place to park cash to build up a position of cash from which to make future equity purchases, the that's fine. But thinking that 10% of an investment in a bond fund will help even out the volatility is crazy.
I suppose re-allocating on a monthly basis might be a reason for a position in bonds or cash.
So, for example, when the larger bucket (VTI) exceeds 50% of total portfolio, see something and re-invest the proceeds in any of the other buckets that are less than their recommended percent (20%, 10%, 10%, 5%, 5%).
But, wow, that's still an incredibly conservative equity portfolio.
How about:
- VTI: 25% (unfortunately that already included a lot of Big Tech)
- VXUS: 25%
- big tech: 30%
- pure quantum: 20%
Because VTI already includes so much Big Tech, how about:
- VXUS: 25%
- VTI: 15%
- top four of the magnificent seven: 35%
- pure quantum: 25%
