This is great! Glad I asked this question. The polling came out pretty tight.

Is “buying the dip” different from “timing the market?”

Let me give you a little opinion and a little fact…

1/ https://twitter.com/BestInterest_JC/status/1350579395048697863
My 2 cents:

They’re the same.

“Don’t time the market” is a way of saying:

• Don’t sell bc you think the market is high
• Don’t buy bc you think the market is low
• Set an investment frequency and stick to it

“Buying the dip” feels like a violation of bullets 2 & 3

Back in Feb ’20, some people on here were freaking out over their perceived great buying opportunity.

The Corona dip had just started. Markets were down ~10%.

3/
But Feb ’20 stock levels were exactly the same as Oct ’19.

Why weren’t they freaking out in October ’19, just 4 months earlier?

Wasn’t that the same great buying opportunity?

I can tell you why.

It’s the same reason your mom freaks out when Old Navy has a 10% off sale.

Our monkey brains react irrationally to discounts.

My thoughts from then (when I first met @BackpackFinanc1!). If you like my Tweets, you’ll like this.

So let’s talk facts:

If you think a “buy the dip” strategy could work, I think you should backtest your strategy against historical data

Don’t have the time for that analysis? No worries.

I did the work and you're 100% welcome to use it.

Article summary:

If used consistently over time, no “buy the dip” strategy ever works.

No strategy. Ever.

Not for 1% dips.
Not for 2%, 5%, 10% dips.

Why not?

Because “buy the dip” implies you’re *holding onto cash* while waiting for that dip.

7/
The market tends to increase in value (with or without you)

Simple example:

You hold cash
The market increases 30%
...then drops 15%
You buy the dip

…and the market is 11% higher after the dip than when we first started!

(1.30 * 0.85 = 1.105 --> 10.5% increase)

8/
This “example” is very simple, yet is borne out time and again over the historical record.

The market goes up more than it goes down.

9/
So, back to my original point:

I think “buying the dip” is the same as “timing the market.”

I also think the facts bear out that “buying the dip” is suboptimal.

And, after all, the reason they tell you “don’t time the market” is because it’s a suboptimal practice!

10/
Ok—enough out of me.

What do you all think?

Useful info? Or am I obviously erroneous?

If you got this far, you rock!

Thanks for reading 🙏
