Question 1

What is a reverse stock split?

Accepted Answer

A reverse stock split consolidates existing shares into fewer, higher-priced shares. In a 1-for-10 reverse split, 100 shares at $2 become 10 shares at $20 — total market cap and the value of your position are unchanged on the effective date. It's the mirror image of a forward split and is used almost exclusively when the current share price is uncomfortably low, typically to defend a stock-exchange listing that requires a minimum bid price.

Question 2

How do I calculate shares after a reverse stock split?

Accepted Answer

Divide your current shares by the reverse ratio's denominator, then multiply by the numerator. For a 1-for-10 reverse split with 500 shares, you'd have 500 × 1 ÷ 10 = 50 shares. The price moves the other way: a $1.50 stock becomes $15. Use this calculator to run any reverse ratio — 1-for-5, 1-for-10, 1-for-20, or even unusual ones like 1-for-100 — and confirm your total portfolio value is unchanged the moment the split takes effect.

Question 3

Why do companies do reverse stock splits?

Accepted Answer

The most common reason is to meet exchange listing requirements — the NYSE and Nasdaq both require a minimum bid price (typically $1) to stay listed, and a reverse split lifts the price above that threshold. Other motivations include appearing more institutional (many mutual funds and pension plans can't buy sub-$5 stocks), reducing the perception of being a penny stock, or preparing for a merger, spin-off, or capital raise where a higher share price simplifies the transaction.

Question 4

Are reverse stock splits bad for investors?

Accepted Answer

Not mechanically — value is preserved on the split date itself, and your ownership percentage is unchanged. But reverse splits often signal underlying business weakness, and empirical studies show that stocks doing reverse splits have historically underperformed the broader market in the years that follow. The split isn't the cause; it's a symptom. Treat the announcement as a prompt to re-underwrite the business, not an automatic sell signal, but do go in with eyes open.

Question 5

How does a reverse split affect my cost basis and taxes?

Accepted Answer

Your total cost basis in dollars doesn't change. A 1-for-10 reverse split multiplies your per-share cost basis by 10 and divides your share count by 10. If the split creates a fractional share, the company typically cashes it out — that small cash payment is a taxable event, but the split itself is not. Brokers automatically update the cost-basis records reported on Form 1099-B when you eventually sell.
