Given the current one-year fixed deposit interest rate of 2.5%, and the historical average return of 5% in the Taiwan stock market over the past 10 years, along with a current B value of 0.9 for North Tech Company, a closing price of 24 yuan today, and a market expectation of a year-end target price of 26 yuan with no plans for stock dividends or stock splits during this period. Considering this information, my investment recommendation for holding North Tech Company's stock would be to continue holding. The potential for capital appreciation, as indicated by the expected target price, and the historical market performance suggest a reasonable outlook for maintaining the investment.
