Scuffles broke out in Cairo on Tuesday as supporters of ousted president Mohamed Morsi clashed with security forces and opponents in the city center.
Preliminary reports indicated that tear gas was fired in the vicinity of the Ministry of Interior, near the Egyptian Stock Exchange.
The prolonged political deadlock has fueled concerns over a forceful intervention by security forces. So far, however, the relative restraint is keeping investors upbeat.
"Cooler heads have prevailed since the removal by force would, we think, likely lead to both high casualties and a significant loss of credibility by the authorities," Angus Blair, founder of the Signet Institute, a Cairo-based think tank, told CNBC.
A flurry of diplomatic activity in recent weeks to crack Egypt's political deadlock has so far failed to produce an agreement. The government has repeatedly asked protestors to go home, and classified ongoing sit-ins as a threat to national security. In the past 48 hours, there has been a visible increase in the presence of both police and military forces across the capital.
The military has also stepped up its campaign against militants in the Sinai Peninsula, home to the Suez Canal. On Tuesday morning, the Israeli military confirmed it had intercepted a missile over Eilat, a resort town on the border with Egypt. Shipping traffic has been unaffected.
But investors appear to be finding renewed confidence in the country's economic prospects. "By ignoring the sit-ins, the government can get on and run the economy," Blair added.

Apart from the political impasse, other indicators may keep the positive momentum in check.
"Leaving aside the drop in debt servicing costs and improved liquidity, little has changed," HSBC analysts said in a research note on Tuesday. "Subsidy spending, which has tripled since 2005, will remain a heavy drain on resources, especially as a weaker exchange rate pushes up import costs."
