Concept:Second-tier securities market exists for companies that cannot meet the strict listing conditions of the first-tier market.
Explanation:The first-tier securities market is meant for well-established, large companies with strong financial records.
Its listing requirements are strict and difficult for smaller companies to satisfy.
The second-tier securities market provides an alternative avenue for smaller or newer companies to quote and trade their securities.
Companies in the second-tier market do not need to meet the high standards demanded by the first-tier market.
Therefore, the second-tier securities market has fewer restrictions for listing and trading securities.
It is designed to be more flexible and accessible to growing businesses.
Thus, unlike the first-tier market, it is less restricted.
