On Monday, the Nepal Stock Exchange index fell 20.48 points to close at 2,566.76, on turnover of Rs 3.27 billion that was weaker than Friday's Rs 3.89 billion. Of 359 companies traded, 242 saw their prices fall and only 32 rose. Market reports blamed several factors at once: dividend-season price adjustments, a weak week already behind the market, and one specific regulation. The Corporate Samachar report named it plainly: a Securities Board of Nepal provision requiring shareholders holding more than 5 percent of a company's shares to disclose before selling, a provision the House of Representatives' Finance Committee has now directed the board to reconsider.

The rule is simple on paper. Under a directive issued on Bhadra 9, 2083, using the authority in Section 84(1) of the Securities Act, 2063, any substantial shareholder of a NEPSE-listed company who intends to sell 5 percent or more of their shareholding must notify the company in writing at least 15 days before the proposed sale. The company must then make the information public through NEPSE. As ShareSansar reported, substantial shareholders are investors holding 1 percent or more in institutions with paid-up capital above Rs 25 crore, and 5 percent or more in other cases. The idea, as the regulator stated it, was to strengthen market surveillance, protect investors, and promote orderly trading by giving everyone equal access to information about coming supply.

The logic is hard to argue with: nobody should be blindsided when a large holder dumps shares. But the information did exactly what markets do with public information, which is act on it. Since the rule took effect, a steady stream of sale notices has been published on NEPSE. Banking News counted 33 shareholders notifying the sale of 75 lakh shares in the weeks after the directive: 12 shareholders of Emerging Nepal, 12 of Kalinchowk Darshan, three individuals of Hathway Investment Nepal moving to sell 885,000 units, Clean Energy Consultants selling 345,000 units of Peoples Hydropower, notices covering Molung Hydropower, Bhagawati Hydropower Development, Upper Lohore Khola, Upper Hewa Khola, and Dolma Impact Fund's holding in Shweta Ganga Hydropower. Each notice is transparent. Each notice is also a public announcement that a large seller is coming. The warning became the overhang.

This is the uncomfortable mechanism at the center of the story. A notice published 15 days before a sale gives buyers time to prepare, but it also gives them a reason to wait. Why buy today when a known block of supply is scheduled to hit the market in two weeks? The rule broadcasts intent to sell, and intent to sell is, in a thin market, nearly as powerful as the sale itself. Analysts have also flagged the rule's one-sided design. The NEPSE Trading desk argued that disclosure applies only to sellers while large buyers accumulate with no equivalent obligation, creating a regulatory imbalance that could just as easily facilitate manipulation on the buy side. Transparency that covers only half the order book is not neutral information.

Monday's session showed what that asymmetry looks like in practice. All 13 sectoral indices fell except trading, which rose 10.71 points. Banking lost 10.73 points, hydropower 36.95, life insurance 93.81, and manufacturing 104.51. Ghalemdi Hydro was the day's most traded stock at Rs 22.87 crore of turnover, rising 2.23 percent to Rs 275, but it was the exception in a market where the risk-off trade was visibly rotating into fixed income: the 10.30 percent Standard Chartered Bank debenture gained 5.75 percent and the 10 percent Nepal SBI Bank debenture rose 4.98 percent, according to The Farsight Nepal. When debentures and mutual funds top the gainers' list, the market is not pricing growth. It is pricing shelter.

The broader context makes the rule's timing worse. The Finance Ministry's 21-point capital market revival plan was announced in mid-September, when NEPSE stood at 2,633.62. The index has fallen in nearly every session since, losing about 67 points to Monday's 2,566.76. A week earlier, the House Finance Committee sat with market stakeholders and issued a five-point directive: a new securities bill clarifying the roles of SEBON, NEPSE and CDS and Clearing; categorized, merit-based IPO approvals; surveillance against cornering, circular trading and pump-and-dump schemes; a NEPSE technology and restructuring push; and filling the long-vacant chief executive posts at NEPSE and CDS. Alongside that package came the sharper, more specific instruction: reconsider the 5 percent provision. The committee that was asked to strengthen the market looked at SEBON's flagship transparency measure and asked whether it was helping.

A few limits are worth stating plainly. No one can isolate how much of Monday's fall, or the week's, belongs to the notice rule. Dividend-season price adjustments are a real mechanical drag on the index, sentiment was already fragile, and turnover has been thinning for days. Correlation is not causation, and a single session never proves a rule wrong. What the evidence does show is a regulator in an awkward position: SEBON published a full concept paper on Ashwin 7 defending the advance-notice framework, its rationale, and its proposed regulatory shape, and within days the parliamentary committee overseeing it was telling it to think again. The notices, meanwhile, keep publishing. Every one of them tells the market the same thing: a large seller is waiting in the wings.

There is a genuine policy dilemma underneath the politics, and neither side is obviously wrong. Sudden promoter dumps have burned retail investors before, and a market where insiders sell without warning is not a fair market. But information has a price. The 15-day window turns private intent into public signal, and the signal lands in a market already short on confidence. The question SEBON now has to answer, with the Finance Committee watching, is the one every regulator eventually faces: whether the protection it designed is costing more than the harm it was built to prevent.
