In technical analysis, a theory dealing with the measure of debts owed to a brokerage on margin accounts. A high debit balance indicates that large or important investors are buying on margin in greater amounts, which is thought to be a bullish indicator. Likewise, a low debit balance indicates that many investors are not buying on margin; this is thought to be bearish. Debit-balance theory assumes that investors thought to be "sophisticated" usually make wise investment decisions; not all analysts agree with this assumption.

A rise in debit balances is generally considered bullish because such balances result from the purchase of securities on margin by sophisticated investors. Compare credit-balance theory.
