Question: Is it reasonable to borrow money at around 3% interest (like WeChat Weili Dai) to invest regularly in NVIDIA stock after experiencing losses and high-interest debt before?

Answer:

Short answer: this is financially risky and generally not a sound long-term strategy, even if the interest rate looks low.

Let’s break it down clearly.

1. The core issue: borrowing to invest = leverage

What you’re doing is essentially leveraged investing:

Borrow at ~3%
Invest in something like NVIDIA
Hope the return > 3%

This can work, but the key problem is:

returns are uncertain, but interest is guaranteed

You must pay 3% no matter what happens.

2. Why it feels “rational” but is dangerous

Your logic is understandable:

3% loan feels cheap
NVIDIA has strong growth → seems likely to outperform
You already reduced high-interest debt → psychologically “safe”

But there are hidden risks:

(1) Market volatility

Even a strong company like NVIDIA can drop:

-20% to -50% is totally normal in tech stocks
If that happens, you’re:
- losing money
- still paying interest
- possibly forced to sell at a loss

(2) Sequence risk (very important)

Even if NVIDIA grows long-term:

If it drops early while you’re leveraged → you get trapped
Timing matters when you borrow

(3) Behavioral risk

You already hinted at this:

“为了英伟达定投才破戒一下” (broke discipline for NVIDIA)

That’s a warning sign.

Leverage + emotional conviction = dangerous combo.

3. Your current balance sheet matters more

You said:

Mortgage: 900,000 RMB
Recently got out of high-interest debt
Still borrowing again

This means:

You are not in a strong surplus position yet

In this situation, the priority should usually be:

Stability
Cash flow safety
Risk control

Not return maximization.

4. What professional investors would say

Most disciplined investors follow this rule:

❌ Don’t use borrowed money for volatile assets ✔ Use leverage only when:

income is extremely stable
assets are diversified
downside is controlled

Even hedge funds blow up from leverage—not because they’re wrong, but because timing kills them.

5. A more robust strategy

Instead of:

borrow → invest → hope

A more resilient version is:

Use free cash flow only for investing
Continue DCA (定投), but:
- no leverage
- no urgency
Treat NVIDIA as one position, not a belief system

6. The psychological layer (important)

Your message shows:

You’ve been through loss (house -1M)
You experienced high-interest debt stress
Now you’re trying to “optimize” again

That often leads to:

trying to accelerate recovery using risk

But the paradox is:

the more you try to speed up recovery, the more fragile your system becomes

7. Bottom line

3% interest is cheap, but not “free”
NVIDIA is strong, but not guaranteed
Borrowing to invest = you’re adding fragility

👉 If your goal is long-term wealth:

consistency > cleverness survival > optimization

If you want, I can help you model a safe investing + debt reduction strategy based on your current situation (cash flow, risk tolerance, timeline).
