Reverse Split

A reverse split is a corporate action that reduces the number of a company's outstanding shares while increasing the price per share by the same proportion, so the total value of the company (its market capitalization) does not change. If you owned 100 shares worth $1 each before a 1-for-10 reverse split, you'd own 10 shares worth $10 each afterward — same $100 total, fewer and pricier shares.

Mechanically, the company picks a ratio, like 1-for-5 or 1-for-20, and every shareholder's shares are consolidated at that ratio. Brokers adjust everyone's account automatically; you don't have to do anything. Any fractional share left over (say you held 7 shares in a 1-for-10 split, leaving 0.7 of a share) is typically paid out in cash rather than issued as a partial share.

The nuance beginners miss is that a reverse split is neutral in theory but often a warning sign in practice. Companies whose stock has fallen to a very low price sometimes use a reverse split to push the price back above a minimum threshold an exchange requires for continued listing, or to look more respectable to institutional investors who avoid low-priced stocks. The split itself creates no new value — it just repackages the same pie into fewer, larger slices — but the fact that a company needed to do this is often a signal that the underlying business has been struggling, which is why reverse splits are frequently followed by continued price declines rather than a turnaround.

For day traders, reverse splits also mechanically change how a stock behaves: with fewer shares outstanding, the stock can become more volatile and harder to trade in size, and historical charts and indicators can look discontinuous around the split date unless properly adjusted.
