A strong capital market is not built by eliminating uncertainty. Markets naturally rise and fall with economic cycles, business conditions and investor expectations. Investors need protection not from volatility itself, but from deception, manipulation, unequal access to information, and unstable rules.
The most effective way for market regulators to protect investors is to prevent misconduct. The best regulators do not wait until fraud destroys wealth before taking action. They build safeguards before risks emerge, monitor market behaviour continuously and ensure that companies and financial intermediaries remain accountable.
This preventive philosophy has shaped modern securities regulation for nearly a century. Two landmark US laws – the Securities Act of 1933 and the Securities Exchange Act of 1934 – created the foundation for a market system built on disclosure, accountability and surveillance. These principles continue to influence securities regulation worldwide, including the framework overseen by the Bangladesh Securities and Exchange Commission.
Together, the two laws created an enduring double-layer security system. One protects investors before companies enter the public market. The other ensures that companies remain transparent after they become publicly traded.
Investors do not require regulators to eliminate normal market movements. They understand that share prices rise and fall as economies expand, businesses perform and expectations change.
Their real concern is being misled by market manipulation, insider trading or fraud by financial intermediaries.
The purpose of regulation is therefore not to guarantee returns or prevent volatility. It is to remove the shadows where dishonest practices thrive.
When regulators create a transparent environment, they build an architecture of trust. That trust allows investors to commit capital with confidence and enables capital markets to perform their broader economic role of directing savings towards productive investment.
The Securities Act of 1933 represents the first line of defence. It acts as the front gate of the financial system by addressing risks at the moment companies seek money from the public.
Before launching an initial public offering, companies must submit detailed registration documents explaining their financial condition, management background and business risks. They cannot legally sell securities until regulators have reviewed the required disclosures.
The law also requires companies to provide investors with a prospectus containing essential information about the business and the risks involved.
The principle is straightforward: investors should know what they are buying before they commit their money.
By forcing companies to disclose material information at the entry point, the law attempts to prevent fraudulent enterprises from reaching investors.
The Securities Exchange Act of 1934 provides the second layer of protection.
If the 1933 Act builds the entry wall, the 1934 Act creates the real-time watchtower.
Once companies begin trading publicly, their responsibility does not end with the IPO. They must continue disclosing financial information through annual and quarterly reports, keeping their performance under continuous public scrutiny.
The law also established the foundation for market surveillance. Regulators monitor trading volumes, unusual price movements and suspicious patterns. With modern technology, these systems can identify abnormal activity faster than ever before and allow authorities to investigate potential manipulation.
The importance of these laws is that they are not designed around a particular technology. They regulate human behaviour – whether companies disclose important information, whether investors receive fair treatment and whether markets operate on trust.
That is why the framework has survived nearly a century, from paper ticker tapes to high-frequency algorithmic trading. Technology has changed. The principle has not.
The durability of these principles became clear when one of the world’s largest technology companies faced legal challenges after entering the public market.
In May 2012, Facebook launched one of the most anticipated initial public offerings in history. However, shortly after shares began trading, the stock price declined sharply, wiping out billions of dollars in investor wealth.
Investors responded by relying on protections established under the Securities Act of 1933 and the Securities Exchange Act of 1934, filing a consolidated class-action lawsuit against Facebook and its underwriters.
The first claim focused on the 1933 Act.
Investors alleged that Facebook’s IPO registration statement was misleading because it failed to disclose a major business challenge: users were rapidly shifting towards mobile devices, while Facebook’s ability to generate advertising revenue from mobile platforms remained limited at that time.
The significance of the claim was that investors did not need to prove that Facebook deliberately attempted to deceive them.
Under Section 11 of the 1933 Act, they only needed to show that the registration documents failed to include a material fact that investors should have known before purchasing shares.
This strict liability principle is one of the strongest investor protections in securities law because it recognises that incomplete disclosure itself can damage market confidence.
The second claim was brought under Section 10(b) of the 1934 Act.
Investors alleged that Facebook executives and Wall Street underwriters had selectively shared lower revenue expectations with institutional investors while ordinary retail investors remained unaware of the same information.
The allegation raised a fundamental question: could a public market remain fair if some investors received important information before others?
The case was not simply about a falling share price. It was about whether all investors had equal access to information that could influence investment decisions.
Facing the combined pressure of a Section 11 claim and a Section 10(b) fraud claim, Facebook and its underwriters recognised the risks of a prolonged legal battle.
Rather than proceed to a potentially damaging trial, Facebook agreed to a $35 million out-of-court settlement to resolve investor claims.
The case demonstrated a central truth of capital markets: no company, regardless of size or influence, operates beyond the responsibility of transparency.
Whether a company is a 1930s industrial conglomerate or a 21st-century social media giant, the same principles remain active.
The lesson for Bangladesh is not about copying another country’s market structure. It is about recognising the importance of stable and credible regulation.
A mature capital market cannot be built through frequent rule changes or repeated policy experiments. Regulation must evolve with changing market conditions, but uncertainty created by unpredictable adjustments can discourage long-term investment.
Despite the century-old global experience of principle-based securities regulation, Bangladesh’s capital market has gone through repeated regulatory experiments that have become a major source of uncertainty for investors.
Rules that change according to the demands of particular groups, or policies that are repeatedly redesigned within short periods, make it difficult for investors and businesses to plan for the future.
A capital market requires confidence that regulations will remain predictable, transparent and consistently enforced.
Bangladesh’s capital market has already developed through decades of experience. The next phase requires a regulatory framework that can serve as a launch pad for the country’s future growth story.
Market development does not come from introducing more rules. It comes from building better rules – rules that investors understand, trust and can rely upon.
The global experience is clear: strong capital markets are built on uncompromised disclosure, regulatory consistency and relentless vigilance.
For Bangladesh, the challenge is not only to create a larger market, but to create a trusted one.
