Markets are falling — what now?

Every investor will sooner or later experience declines. Correction (-10%), bear market (-20%) or crash (-30%+) — it's a normal part of market cycle. Key question: what to do with your money when red floods your portfolio?

Three popular strategies are: buy the dip, DCA and waiting for bottom. Each has its pros and cons.

Strategy 1: Buy the dip

What is it?

You buy more stocks or ETFs at reduced price. You treat the decline as a sale.

Pros

  • Buy cheap, sell expensive — fundamental investing principle
  • Lower your average purchase price
  • Historically markets rise after falls

Cons

  • You don't know where bottom is — "dip" can turn into "crash"
  • Requires free cash at the right moment
  • Emotionally difficult — buying when everyone panics
  • Market timing rarely works

When to use?

  • You have cash cushion designated for opportunities
  • Company fundamentals haven't changed
  • Decline is caused by panic, not fundamental change

Strategy 2: Dollar Cost Averaging (DCA)

What is it?

You invest fixed amount at regular intervals (e.g., 1,000 PLN monthly), regardless of what market does.

Pros

  • Eliminates emotions from investing process
  • No need to hit bottom — you automatically buy more when it's cheap
  • Simple to implement — standing order and done
  • Statistically gives very good results

Cons

  • In uptrend, lump sum gives better results in ~67% of cases
  • Slower position building
  • Requires patience and consistency

When to use?

  • Regular work income
  • Don't want to analyze market daily
  • Long investment horizon (10+ years)
  • Starting your investing journey

Strategy 3: Waiting for bottom

What is it?

You sit on cash and wait for market to "reach bottom" — lowest point — to buy as cheap as possible.

Pros

  • Theoretically maximizes profit
  • Protects capital from further declines

Cons

  • Nobody knows where bottom is — nobody
  • "Time in the market beats timing the market" — historical data confirms this
  • Opportunity costs — money in account loses to inflation
  • Decision paralysis — always waiting for "better opportunity"
  • Risk that market bounces and you buy more expensive than before decline

When to use?

  • Almost never as sole strategy
  • Possibly: keep part of cash (10-20%) for exceptional opportunities

What does data say?

Studies by Vanguard and other institutions show:

  1. Lump sum > DCA in ~67% of cases (markets rise more often than fall)
  2. DCA > waiting almost always
  3. Worst timing for investment still beats no investment over long horizon

Example: if you invested in S&P 500 on worst possible day each year (right before biggest decline) for 20 years — you'd still earn more than on savings account.

Hybrid strategy (best for most)

  1. 80% of capital — invest regularly through DCA (e.g., monthly)
  2. 20% of capital — keep as "opportunity reserve" for buy the dip
  3. At >10% decline — invest 1/3 of reserve
  4. At >20% decline — invest another 1/3
  5. At >30% decline — invest the rest
  6. Never wait for bottom — invest systematically

Psychology of declines

Declines activate strongest cognitive biases:

  • Loss aversion — pain from losing 1,000 PLN is 2x stronger than joy from gaining 1,000 PLN
  • Recency bias — you think declines will last forever
  • Herd mentality — everyone's selling, so you want to too
  • FOMO — fear of buying "falling knife"

Best defense? Investment plan written on paper BEFORE declines. When emotions take control, you stick to the plan.

Checklist for declining times

  • Do I have safety cushion (3-6 months expenses)?
  • Are my debts paid off?
  • Am I investing money I don't need within 5+ years?
  • Have fundamentals of my companies/ETFs changed?
  • Do I have written investment plan?

If you answered "yes" to everything — keep investing. Declines are normal part of the game.
