Experts say that there is ample idle capital available for inflow into the stock market. According to the financial investment industry, the balance of margin loans stands at 12.4 trillion won, and deposits at 69 trillion won.

Tariff uncertainty is considered a risk factor. With the possibility of the tariffs set to take effect in July being further postponed, there was a positive breeze in the U.S. stock market last week. However, over the weekend, U.S. President Donald Trump reiterated his stance on imposing tariffs as scheduled.
As a result, market anxiety over tariffs is starting to resurface. Researcher Lee Jae-won analyzed, "For the Korean stock market to continue rising, it is necessary to alleviate concerns about tariffs and earnings."
Some analysts suggest that the uncertainty surrounding the tariff war has already been sufficiently reflected in the market. It is anticipated that uncertainty will be somewhat alleviated once the mutual tariff rates are confirmed early next month.
An Ki-tae, a researcher at NH Investment & Securities, stated, "It will be difficult for U.S. tariff rates to drop further from their current levels, and there is also a limit to raising them. If the increase in tariffs is limited to 13%, the decline in corporate profits will not be prolonged."
