# Recital 4

*In force · Regulation (EU) No 600/2014, OJ L 173, 12.6.2014 · Checked against EUR-Lex on 1 Nov 2026 · [Official source](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32014R0600)*

Directive 2004/39/EC established rules for making the trading in shares admitted to trading on a regulated market pre-trade and post-trade transparent and for reporting transactions in financial instruments admitted to trading on a regulated market to competent authorities. The directive needs to be recast in order to appropriately reflect developments in financial markets and to address weaknesses and close loopholes that were, inter alia, exposed in the financial market crisis.
