πŸ“Œ Why Dollar-Cost Averaging (DCA) Instead of Timing the Market


DCA (Dollar-Cost Averaging) is when you invest a fixed amount of money at regular intervals (e.g. every month) regardless of market price.

Market timing is trying to predict when prices will go up or down and investing only at what you believe is the "right time."

πŸ“ˆ Why DCA Is Often Better for Most People

βœ… 1. You Can’t Predict the Market Consistently

Even the best professional investors struggle to consistently time the market correctly. Most retail investors get it wrong β€” buying high (FOMO) and selling low (panic).

Example:

You think Bitcoin will drop from $60k to $50k β€” it runs up to $65k instead and you missed out.

βœ… 2. Removes Emotion from Investing

Human emotions (fear, greed, FOMO, panic) cloud judgment. DCA makes you invest mechanically, regardless of market noise.

Example:

If you only buy when you "feel good" about the market, you'll likely buy high and avoid good opportunities during dips.

βœ… 3. Reduces the Impact of Volatility

When markets are volatile, DCA smooths out your entry price over time β€” sometimes you’ll buy high, sometimes low, but you’ll avoid dumping everything in at the top.

Example:

Invest $500/month for a year vs lump sum at one moment β€” in a volatile market, your average entry price is likely more favorable than risking one poorly timed big entry.

βœ… 4. Builds a Sustainable, Long-Term Habit

Wealth is built through consistent, long-term investing β€” not lucky one-off trades. DCA encourages regular investing discipline, which compounds over time.

βœ… 5. Time in the Market Beats Timing the Market

Historically, staying invested long-term outperforms trying to jump in and out. Missing even the 10 best days in the market can drastically hurt returns.

Example:

In US stocks (S&P 500 from 1990-2020):

Fully invested: +9.29% annual return

Missed 10 best days: +5.33%

Missed 20 best days: +2.72%

And the best days often happen during bear markets or right after crashes β€” when most people are too scared to invest.

πŸ“Œ When Timing the Market Could Work

If you have a unique informational advantage (very rare)

If you're a full-time trader with strict risk management

During obvious bubbles or macro events (e.g. Fed pivot, COVID crash β€” but these are hindsight obvious)

Even then β€” extremely risky.

βœ… Bottom Line:

DCA Market Timing

Removes emotion Relies on prediction

Smooths out volatility High risk of missing out

Long-term consistent returns Inconsistent outcomes

Waiting Game: Nvidia at Highs, Add at $170 or Wait $150?
Nvidia’s Q2 revenue rose over 55%, but revenue in China dropped sharply by 24%, wiping out $93B in market value. After the last earnings report, Nvidia pulled back and consolidated before breaking to new highs, eventually climbing to $180. This time, the earnings aren’t actually bad β€” the recent surge just front-loaded the gains. 1. Is $170 the start of Nvidia’s new bull market, or should we wait for a pullback to the $150 support level? 2. What’s your choice β€” is it ever too late to buy Nvidia? 3. How will AVGO affect Nvidia stock price?
