How do you get the 7.53% yielding (in red circle)?

6) Realized Compound Yield (RCY): For mera maturity an example: Holding Period = 4yrs 10- Face Value = $1,000 Annual coupon = $70 Price = $932.90 I = 8.25% Investor's total return is made up of reinvestment of coupons and the sale of the bond. RCY = 8.25% vs. YTM 8.00% X YTC 9.07% X IRR 8.50% X 6 Realized Compound Yield (RCY) is just a simple TVM PV-FV problem over the holding period
